• Envy 17 t J000 - maximum hard drive size and speed

  I'm going to put a 2nd hard drive into the open space in my Envy 17 t-j000.

  The States of Maintenance and Service Guide;

  Hard drives Supports 6.35 cm (2.5 in.) 9.5 mm hard disks (. 37-in) and thicknesses of 7.0 mm (. 28 - in) (all hard drives use the same bracket)

  Customer-accessible

  Serial ATA

  Supports the following drives:

  ● 1 TB 5400 RPM, 9.5 mm

  ● 750 GB 5400 RPM 9.5 mm

  ● 500 GB 5400 RPM 9.5 mm and 7.0 mm

  Configurations to two hard disks:

  ● 2 TB: (1 TB 5400 RPM x 2)

  ● 1500GO: (750 GB 5400 RPM x 2)

  This seems to mean that I cannot use a single hard drive 2 TB 2 and cannot use a 7200 RPM drive.

  Is this correct? Bios denominator do not allow more than a drive of 1 TB or the 7200 RPM?

  CouldI partition just the 2nd 2-1 TB disk?

  Or the manual simply means that the standard unit of HP is not provided with larger than these sizes and I could actually use a 2 TB in the Bay of 2nd?

  It's the last... the list says just what HP sale: it does not describe a limitation of the system. However, I do not think that yet, the market offers a 2 TB drive that fits the available space. 2 TB 2.5-inch SATA drives I've seen are too thick. 7200 rpm or hybrid SSD; No problem.

  To add a second drive you'll need a second hard drive enclosure and cable.

• Cloning a virtual machine to a disk size and model

  Hi all, I cloned successfully a vm from a template. I resized the HDD in a new size of 50 GB 20 GB models and completed the conversion. The clone, the space allocated to the system partition remained 20 GB and shows the remaining new size (30 GB) size as unallocated space in disk management.

  I called the Technical Support Center and they said that this is how it is supposed to be the case, although I previously resized the HDD when cloning and successfully using all the space reconfigured to the system partition. They recommended to convert the clone (using the converter) on another virtual computer and resize the disk. Anyone with a concrete solution to this is very welcome.

  You are welcome.

• Questions of size and speed of Collection stored

  Hello everyone,
  
  Developing a search engine for text, I was looking for a quick tool and low level storage. Berkeley DB I got and it seemed to suit my needs. I used Java cards to my process if it appeared logical to use the Collections API.
  
  Structure database (or card):
  
  DOCUMENT MAP
  - docKey a simple integer ID generated in the order
  - docEntry small number of properties
  
  
  TERMMAP
  - termKey, a unique string value
  - termEntry small number of properties
  
  INDEXMAP
  - indexKey two foreign key values: docKey, termKey
  -number of occurrence indexEntry of this term in the doc
  There is a secondary index for INDEXMAP termKey interrogation.
  
  I use the tuples of the key entities serializable for entries and I removed the redundant entities serializable key value using the transient modifier.
  
  Here's the algorithm
  The program retrieves the terms of a document and add the doc in the DOCUMENT Explorer.
  For each term, if it is not in the TERMMAP, it is inserted.
  This isn't in the INDEXMAP, it is inserted and the number of occurrence = 1 if the number of occurrence is triggered.
  DOCUMENT map is quite small, while TERMMAP and INDEXMAP in particular have a huge amount of entries.
  
  When testing it, it has very well worked and provided a quick mark. However, I noticed a few problems that could be critical:
  
  -The size of the log is very high
  1, 5 GB size of total newspaper for 100 MB of text indexing, then the same index (without the secondary index) takes 100 MB in ASCII text.
  I tried to reduce the total log by increasing CLEANER_MIN_UTILIZATION but it has not reduced sufficiently.
  I thought that maybe does not keep good things, but by displaying the contents of the card, all goes well, no redundancy.
  
  -The storage is too slow
  With a simple file storage, it's very fast if the bottleneck comes from db storage.
  I noticed that it is faster to store temporary data in java cards (TreeMap to have sorted input values), then add them to the maps stored than to use the saved directly map.
  
  To conclude
  
  My final goal is to process a huge amount of data (collections of giga or terabyte) and I'll probably have to use parallel processing. However, if a simple test gives good results, I fear that I'll have to find another way to store my data.
  
  This is the first time that I use berkeley db, so maybe I did something wrong. To avoid asking help for nothing I tried a lot of changes in the configuration: size, cleaner use, size of the cache, off transactional stuff and nothing gave significant results. I followed the tutorial for Java Collections and read the Javadoc. Finally, I used the JConsole plugin to take a look at the stats. This is my last chance...
  
  If more details are needed, just ask,
  Thank you in advance,
  Nicolas.
  

• Running out of disk space and the need to remove the old clichés

  I recently joined a company owning an ESXi 4.1.0 (build 260247) server with 4 500GB data warehouses.  One of our servers main database (Ubuntu/Postgres), which uses only one of the data warehouses (4 datastore) has 21GB 465 GB free.  It is currently configured to store all settings, storage and snapshots on this unique data store.  The hard disk is configured as thin.

  The virtual machine has crashed a few days ago, when it ran out of disk space.  We removed a small second partition (which was in the same data store) and cleared space, but we receive extremely weak with only 5% of the data left store.

  I have read many posts and wanted to get the opinion of this community before I move forward.   Because we do not use the 4.1 last I heard some issues using the option "Remove all" that it may require more disk space and others recommended to manually delete snapshots from the closest to the base, but it seems that in this case it can merge the snapshot with the original without freeing all the space.

  We are not all of the snapshots and I'm fine with delete them, but I assure you we will not run out of disk space in the process and complicate things further.

  It is best to manually remove these snapshots starting with the one closest to the base or by using the "Delete All" (or something else)?  In addition, if we go with the manual option, is it possible with the virtual machine upward or do we need to close first?

  Current snapshots:

  Welcome to the community,

  After the screenshot, your virtual disk 'arrow_db1.vmdk' stocked thickness!

  With the thick disc service and ESXi 4.1 (the problem with "Delete All" is related to version 4.0), you can run safely "Delete All". However, due to low disk space, I recommend that do you with the virtual machine off. If turned on, a new temporary snapshot will be created, which - according to the workload of the virtual machine - can grow and fill in the data store.

  Due to the size of snapshot and depending on the speed of your storage space, you need to plan a few hours well downtime.

• Should we leave how much free space on the C drive before affecting the performance and speed?

  Hello!

  Hard drive of my new PC (C) is 1 TB (processor Samsung 7i, Windows 8.1). It doesn't have any other disk/partition. How this space is safe to use to store large files (videos, esp., stored in the native video library file) without harming the performance and speed?

  And if I create another partition (D) and just use it for storage, it will make much difference compared to the above?

  Planning your Partitions

  The Question

  Partitions, how much should I have on my hard drive, what do I use
  each of them for, and what size should each one be?

  It s a common question, but unfortunately this doesn t have a
  only simple, just answer to all the world. A lot of people will respond with
  the way they do, but their response isn't necessarily best for the
  person seeking (in many cases it isn't right even for the person)
  response).

  Terminology

  First, let's rethinking the terminology. Some people ask "should I".
  partition my drive? That s the wrong question, because the
  the terminology is a little strange. Some people think that the word
  "partition" means divide the drive into two or more partitions.
  That s not correct: to partition a drive is to create one or several
  partitions on it. You must have at least one partition to use
  He who think they have an unpartitioned disk actually
  have a player with only one partition on it and it s normally
  Called C:. The choice you have is to have more than one
  partition, not that it's the partition at all.

  A bit of history

  Back before Windows 95 OEM Service Release 2 (also known as Windows
  95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
  using the file system FAT16 (except for very tiny to aid
  FAT12). That 16-bit only because were used for addressing, FAT16 has a
  maximum 2 GB partition size.

  More than 2 GB of hard disks were rare at the time, but if you had
  one, you must have multiple partitions to use all the available
  space. But even if your drive was not larger than 2GB, FAT16 created
  Another serious problem for many people - the size of the cluster has been
  more great if you had a larger partition. Cluster sizes increased from 512
  bytes for a partition to no greater than32Mb all the way up to 32 KB for a
  partition of 1 GB or more.

  More the cluster size, the space more is wasted on a hard drive.
  That s as space for all the files is allocated in whole clusters
  only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
  greater than 32 k byte takes 64 k and so on. On average, each file
  about half of his last group waste.

  If large partitions create a lot of waste (called "soft"). With a 2 GB
  FAT16 drive in a single cluster, if you have 10,000 files, each
  lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
  back in an important part of a player that probably cost more than $400
  1996 - around $ 32.

  So what did the people? They divided their 2 GB drive in two,
  three or more logical drives. Each of these logical drives has been
  smaller the real physical disk, had smaller clusters, and
  so less waste. If, for example, she was able to keep all the partitions
  less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
  a quarter of what it would be otherwise.

  People partitioned for other reasons also, but back in the days of
  FAT16, it was the main reason to do so.

  The present

  Three things have changed radically since 1996:

  1. the FAT32 and NTFS file systems came along, allowing a larger
  partitions with smaller clusters and so much less waste. In
  with NTFS, cluster sizes are 4 K, regardless of the size of the partition.

  2 hard drives have become much larger, often more than 1 TB (1000 GB) in
  size.

  3 hard drives have become much cheaper. For example, a 500 GB drive
  can be bought today for about $50. That s 250 times the size of this
  Player 2Gb typical 1996, about one-eighth of the price.

  What these things mean together which is the reason to be old to have
  multiple partitions to avoid the considerable wastage of disk space left.
  The amount of waste is much less than it used to be and the cost of
  that waste is much less. For all practical purposes, almost nobody does
  should no longer be concerned about slack, and it should no longer be
  has examined when planning your partition structure.

  What Partitions are used for today

  There are a variety of different ways people put in place several
  scores of these days. Some of these uses are reasonable, some are
  debatable, some are downright bad. I'll discuss a number of Commons
  partition types in the following:

  1. a partition for Windows only

  Most of the people who create such a partition are because they believe
  If they never have to reinstall Windows properly, at least they
  He won t lose their data and he won t have to reinstall their applications.
  because both are safe on other partitions.

  The first of these thoughts is a false comfort and the second
  is downright bad. See the analysis of the types of partition 2 and 4
  below to find out why.

  Also note that over the years, a lot of people who find their windows
  partition that has begun to be the right size proves to be too
  small. For example, if you have such a partition for Windows and later
  upgrade to a newer version of Windows, you may find that your Windows
  partition is too small.

  2. a partition for installed programs

  This normally goes hand in hand with the partition type 1, a partition for
  just Windows. The thought that if you reinstall Windows, your
  installed application programs are safe if they are in another
  partitions is simply not true. That s because all programs installed
  (with the exception of an occasional trivial) have pointers to the inside
  Windows, in the registry and elsewhere, as well as associated files
  buried in the Windows folder. So if Windows, pointers and
  the files go with it. Given that the programs need to be reinstalled if Windows
  the fact, this reasoning to a separate partition for programs not
  work. In fact, there is almost never a good reason to separate
  Windows of the software application into separate partitions.

  3. a partition for the pagefile.

  Some people think mistakenly that the pagefile on another
  score will improve performance. It is also false; It doesn t
  help and often I hurt, performance, because it increases the movement of the head
  to get back to the page to another file frequently used
  data on the disk. For best performance, the paging file should normally
  be on the most widely used score of less used physical player. For
  almost everyone with a single physical disk than the same drive s
  Windows is on C:.

  4. a partition for backup for other partitions.

  Some people make a separate partition to store backups of their other
  or partitions. People who rely on a "backup" are a joke
  themselves. It is only very slightly better than no backup at all.
  because it leaves you likely to be simultaneously the original losses
  and backup for many of the most common dangers: the head crashes and other
  types of drive, serious glitches to power failure, near lightning
  strikes, virus attack, even stolen computer.  In my opinion,.
  secure backup must be on a media removable and not stored in the
  computer.

  5. a partition for data files

  Above, when I discussed separate Windows on a clean partition,
  I pointed out that separate data from Windows is a false comfort if
  He of done with the idea that data will be safe if Windows ever
  must be reinstalled. I call it a false comfort that's because
  I'm afraid many people will rely on this separation, think that their
  data are safe there and so do not take measures to
  Back it up. In truth the data is not safe there. Having to reinstall
  Windows is just one of the dangers to someone a s hard disk and not
  probably even one. This kind of "backup" falls into the same
  category, as a backup to other partitions partition; It lets you
  sensitive to the simultaneous loss of the original and the backup on many of
  the most common dangers that affect the entire physical disk, not
  just the particular partition. Security comes from a solid backup
  diet, not how partition you.

  However, for some people, it may be a good idea to separate Windows and
  programs on the one hand of the data on the other, putting each of the
  two types into separate partitions. I think that most people
  partitioning scheme must be based on their backup system and backup
  plans are generally of two types: whole hard disk imaging
  or data only backup. If you back up data, backup is
  usually facilitated by the presence of a separate with data only partition;
  to save just the score easily, without having to
  collect pieces from here and elsewhere. However, for
  those who backup by creating an image of the entire disk, there is
  usually little, if any, benefit the separation of data in a partition of
  its own.

  Furthermore, in all honesty, I must point out that there are many
  very respected people who recommend a separate partition for Windows,
  Whatever your backup plan.  Their arguments haven t convinced
  me, but there are clearly two views different here.

  6. a partition to image files

  Some people like to deal with the images and videos as something separate
  other data files and create a separate partition for them. To my
  the spirit, an image is simply another type of data and there is no
  the advantage in doing so.

  7. a partition for music files.

  The comments above related to the image files also apply to music
  files. They are just another type of data and must be dealt with the
  just like the other data.

  8. a partition for a second operating system to dual-boot to.

  For those who manage several operating systems (Windows Vista, Windows
  XP, Windows 98, Linux, etc.), a separate partition for each operating
  system is essential. The problems here are beyond the scope of this
  discussion, but simply to note that I have no objection to s
  all these partitions

  Performance

  Some people have several partitions because they believe that it
  somehow improves performance. That s not correct. The effect is
  probably low on modern computers with modern hard disks, but if
  whatever it is, the opposite is true: more music mean poorer
  performance. That's because normally no partition is full and it
  so are gaps between them. It takes time for the drive s
  read/write heads to cross these gaps. Close all files
  are, faster access to them will be.

  Organization

  I think a lot of people overpartition because they use scores as a
  organizational structure. They have a keen sense of order and you want to
  to separate the apples from the oranges on their readers.

  Yes, separating the different types of files on partitions is a
  technical organization, but then is to separate different types of
  files in folders. The difference is that the walls are static and
  fixed in size, while the files are dynamic, changing size automatically
  as needed to meet your changing needs. This usually done records
  a much better way to organize, in my opinion.

  Certainly, partitions can be resized when necessary, but except with the latter
  versions of Windows, which requires a third-party software (the and the
  possibility to do so in Windows is primitive compared to the third-party
  solutions). These third party software normally costs money and not
  any point and how stable it is, affects the entire disk.
  with the risk of losing everything. Plan your partitions in
  first place and repartitioning, none will be necessary.  The need
  to repartition usually occurs as a result of overpartitioning in
  the first place.

  What often happens when people organize with partitions instead
  records are that they make a miscalculation of how much room they need on each
  This partition, and then when they run out of space on the partition
  When a file is logically, while having plenty of space
  on the other hand, they simply saving the file in the score of "poor".
  Paradoxically, therefore, results in this kind of score structure
  less organization rather than more.

  So how should I partition my drive

  If you read what came before, my findings will not come as a
  surprise:

  1. If your backup set is the image of the entire disk, have just one
  single (usually c partition :));

  2. If you backups just data, have two partitions one for Windows and
  application programs installed (usually c :)), the other for data
  (normally D :).)

  With the exception of multiple operating systems, it is rarely
  any advantage to have more than two partitions.

• disk size problm after copying a large file to the VM then disconnected

  Dear Sir

  I have a VM with allowances dynamic storage virtual hard drive of 300 GB,.

  HE on that disk space is 50 GB.

  Ive copied on it a 100 GB file so now space space disc is 150 GB and 150 GB is free.

  Ive deleted the file 100 GB of the virtual machine, but am supersized now that the file of the virtual machine is still 150 GB in size.

  What should do? as it fits the 50 GB after deleting the file from the virtual machine.

  Hello

  Yes it is planned.

  You have copied a huge file in the virtual computer-> who is the virtual disk in order to accommodate the new file->

  You remove the huge file-> your take off just to comments operating system, the file in the list of the directory->

  Your data is still there, it does not erase the data and rewrite from scratch.

  In order to recover the disk space, you need a number of things:

  -first of all your guests, OS file system must be supported (Windows FAT/NTFS is)

  -Your guest must be stopped

  -The type of the guest operating system disk should not be preallocated.

  -Your host operating system might need a lot of free space on the drive according to your VM disk configuration.

  If stored in several files, you must have a few GB free (size of the Ramdisk / 32) Go, but say more than 4 GB, keep 10 GB free to be on the safe side.

  If your virtual machine is stored in a single file, so you must have your used VM disk size + a few GB of free... for example. If your virtual disk is currently using 200 GB you need tell 204 GB free before starting the operation of a compact disc.

  Then in the configuration of VMware go into settings of virtual machines:

  

  Use the 'Compact disc' button.

  Be very very patient and wait, because you want to get 100GB which will take some time.

• disk memory and space requirment for development database

  Hi all
  
  I want to know the disk space and memory required for the configuration of the environment development database.
  
  Production database size is max 25 to 30 concerts
  and only 3 user will use this database
  
  on this info my suggesion is to go with 3 GB memory 60 GB of backup space and archivelog. Let me know experts comment on that

  How long lasts this string? ++

  So, in other words - it depends. Development environment might include a database logic dev (containing data from prod), one database Q & A logic (to test changes in dev) and a complete copy of the prod database logic (to test the final deployment).

  It could contain an R & D environment - where all data from prod is necessary for data mining research and then to deploy processes of extraction of useful data in the production.

  It could be used in a number of ways - and some of them will be more intensive in the transformation and requiring more data, than the production.

  Ideally - dev environment should look like as close as possible to the prod environment. Ideally, that means a server hardware and similar size, same o/s and Oracle versions and same volumes of data.

• The distribution of applications and data between the disk SSD and HDD

  I recently installed an SSD in my Macbook Pro (late 2011) instead of the DVD player. I want to install OS X on it, by replacing the current OS X on the original hard disk, I will continue to use for storing files. How should I allocate its use in car? OS X and applications on the data files on the hard disk of 500 GB and SSD?

  The first series of instructions will partition and format the newly installed SSD disk then install OS X on it. The second block will help you configure OS X on the SSD with your data on the HARD drive.

  Clean Install of El Capitan on a new disc

  1. Restart the computer. Immediately after the chime, press Command + Option + R until a globe appears.
  2. The Utility Menu appears in 5 to 20 minutes. Be patient.
  3. Select disk utility, then click on the continue button.
  4. When loading disk utility, select the drive (generally, the entry Out-bumpy) in the list aside.
  5. Click the Partition tab in the main window of disk utility. A panel will fall.
  6. Set the GUID partition scheme.
  7. Define the type of Format Mac OS extended (journaled).
  8. Click on the apply button, then click the fact when it is active.
  9. Quit disk utility and re-enter the Utility Menu.
  10. Select reinstall OS X and click on the continue button.

  How to use an SSD with your HARD drive If you want to use an SSD as boot with your existing HARD disk drive, as the disk 'data', here is what you can do. After installing the SSD, you need to partition and format the SSD using disc utility disc. Then install OS X on the SSD. Once installed OSX boot from SSD. Startup disk preferences to set up the SSD as the boot volume. Open the preferences users and groups. Click the lock and authenticate you. Or CTRL - RIGHT click on your username account list in the sidebar and select Advanced Options in the context menu. You will see a field called "Home dir: ' on the far right, you will see an Edit button. Click on it. In the file dialog box, navigate to the location in house now located on the HARD disk (disk HARD/users/user_name /.) Select the folder, click the Open button. Restart the computer, as shown. When the computer starts, it will now use the home located on the HARD drive folder. Another more technical method involving the Terminal and the alias is discussed in depth here: using OS X with a SSD and HDD - Matt Gemmell configuration. It's my preferred approach because I can choose which records of the House, I want to on the HARD drive and I don't want to. For example, I like to keep Documents and library files on the SSD because I frequently access their content. Make sure that you keep the bootable system entirely on your HARD drive where you need it.

• SSDS must be similar in size and type to raid 0?

  SSDS must be similar in size and type to raid 0?  I have a 2009 MBP 2.66 bicoeur.  SSDS are an old sata 250 GB Samsung 850 pro III and an all new Intel 160 GB (320 series) sata II.  The hard drive on the MBP interface is 3.0 GB/s sata optical drive interface is 3.0 Gbit/s

  Different size, different brand, sata II issue III v?

  If it works, it will be almost double the read and write rates, I understand.  I am aware of the increased risk of data loss.  Will only use for backup data.

  How is it difficult to set up raid 0?  I don't know the first thing about raid 0, 1, 2, 3?

  Thank you

  Stu

  If it works, it will be almost double the read and write rates, I understand.

  RAID offers for the SECOND and the following read/write of the same LARGE file acceleration and not otherwise. Any intervention of reading or writing in different files eliminates the acceleration. Any acceleration is much more dramatic on rotating discs, because it can eliminate some of the 10 ms or more long 'dead time' while the reader is a new track and the controller must wait for the correct data go in the position under the read/write head. Acceleration on the low-latency SSDS is far less dramatic.

  The system drive / boot is particularly bad choice for a RAID, it reads and writes small random files in all directions. Who will get no acceleration.

  You can best be served by creating a workflow that allows separate readers for the source files to Destination files, files of zero and drive system / boot.

  --------

  RAID is usually done on the disks that are exactly or nearly the same. Too slow response of one of the discs can cause the RAID failure.

  RAID support has been removed the disc utility GUI in 10.11 ElCapitan, probably because too many casual users got into trouble with the built-in GUI functions. You need to use the diskutil command in the Terminal, or buy the SoftRAID(4) package.

• Maximum disk size for Z61m?

  I want to replace the original 80 MB HARD drive of my Z61m by a faster and bigger. What't maximum disk size THE controller BIOS / able to face?

  Any laptop SATA drive will do just fine, whether it's 160 GB or 320 GB. You know your needs and your budget best.

  I hope this helps.

• buffer size and sync with the cDAQ 9188 problems and Visual Basic

  Hi all, I have a cDAQ-9188 with 9235 for quarter bridge straing caliber acquisition module.

  I would appreciate help to understand how synchronization and buffer.

  I do not use LabView: I'm developing in Visual Basic, Visual Studio 2010.

  I developed my app of the NI AcqStrainSample example. What I found in the order is:

  -CreateStrainGageChannel

  -ConfigureSampleClock

  -create an AnalogMultiChannelReader

  and

  -Start the task

  There is a timer in the VB application, once the task begun, that triggers the playback feature. This function uses:

  -AnalogMultiChannelReader.ReadWaveform (- 1).

  I have no problem with CreateStrainGageChannel, I put 8 channels and other settings.

  Regarding the ConfigureSampleClock, I have some doubts. I want a continuous acquisition, then I put the internal rate, signal source 1000, continuous sample mode, I set the size buffer using the parameter "sampled by channel.

  What I wonder is:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  Thank you very much for the help

  Hi Roberto-

  I will address each of your questions:

  (1) can I put any kind of buffer size? That the limited hardware of the module (9235) or DAQ (9188)?

  The samplesPerChannel parameter has different features according to the synchronization mode, you choose.  If you choose finished samples the parameter samplesPerChannel determines how many sample clocks to generate and also determines the exact size to use.  But if you use streaming samples, the samplesPerChannel and speed settings are used together to determine the size of the buffer, according to this excerpt from the reference help C DAQmx:

  

  Note that this buffer is a buffer software host-side.  There can be no impact on the material available on the cDAQ-9188 or NI 9235 buffers.  These devices each have relatively small equipment pads and their firmware and the Driver NOR-DAQmx driver software transfer data device to automatically host and the most effective way possible.  The buffer on the host side then holds the data until you call DAQmx Read or otherwise the input stream of service.

  (2) can I read the buffer, let's say, once per second and read all samples stored in it?

  Yes.  You would achieve this by choosing a DAQmx Read size equal to the inverse of the sampling frequency (during 1 second data) or a multiple of that of the other playback times.

  (3) do I have to implement my own buffer for playback of data acquisition, or it is not necessary?

  No, you should not need to implement your own stamp.  The DAQmx buffer on the host side will contain the data until you call the DAQmx Read function.  If you want to read from this buffer less frequently you should consider increasing its size to avoid the overflow of this buffer.  Which brings me to your next question...

  (4) because I don't want to lose packets: y at - it a timestamp index or a package, I can use to check for this?

  DAQmx will meet you if all packets are lost.  The default behavior is to stop the flow of data and present an error if the buffer of the side host DAQmx overflows (if, for example, your application does not pick up samples of this buffer at a rate equal or faster than they are acquired, on average).

  If, for any reason, you want to let DAQmx to ignore the conditions of saturation (perhaps, for example, if you want to sample continuously at a high rate but want only interested in retrieving the most recent subset of samples), you can use the DAQmxSetReadOverWrite property and set it to DAQmx_Val_OverwriteUnreadSamps.

  I hope this helps.

• Envy touchsmart 15 - new HARD disk size

  I recently ordered a Touchsmart from HP Envy 15-j005sa that has a 1 TB HARD drive. I'm looking to clone the orignial in an mSATA SSD drive so I was wondering what size is recommended.  How much space is used when it is new so using this information can buy a large enough disk size?

  Thanks in advance

  Hello

  There is that little clone options b clone the HARD disk which means that you have the mSATA SSD equal or more 1 TB (b) clone c ONLY: This means you the mSATA SSD equal or superior to c:... My suggestion: shrink C: for small size say even 60 GB or 120 GB (if you don't have a lot of programs installed) FRONT of clone and ONLY clone C: normally larger (capacity) is better because you can install more programs that him.

  Kind regards.
