• 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?

  Thank you!

  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.

  Anything can be corrupted on your MacBook Pro, but from what you say, it seems that the cable drive/SSD/flash memory/SATA hard was seriously damaged. Him "question mark" means that your Mac is unable to find any bootable device, meaning that it does not yet detect your OS X drive.

  You should make a backup of your files (if you can still do it) and take the Mac at the Apple Store or dealer to get a diagnosis. There may be several damaged parts.

• During execution of the backup and maintenance on one of my computers, I noticed a folder and the file that I can't identify me...

  Original title: identity of unknown folder

  During execution of the backup and maintenance on one of my computers (Windows xp home, sp3), I noticed a folder and the file that I can't identify.  The name of the folder is cc68f6b7a7ca948eefb018f001 and the name of the update.exe file.  The properties of the file that it is a Windows Service Pack installation.  I tried Googling the name of the folder, but found nothing.

  Can you tell me with regard to this issue, and what, if anything, I have to do?

  Thank you.

  When some programs (including Windows) installs things, it can create a temporary folder composed of 20-30 random letters and numbers or random numbers and letters in the root of the drive of the volume with more free space.

  This explains why the records are sometimes on your C drive or any other drive - the most space?

  For example, you can see a similar to or called folder:

  D:\9470bb12e8a4f3447657236478e41c5

  There may be other folders and files in this main temporary folder such as amd64 and i386 platforms.

  They should normally be deleted when the installation is complete, but sometimes they are not - especially if the installation fails.  They are harmless but annoying.  You can think something is wrong when there are no or fear, that the files are really necessary.  To avoid confusion, you can delete the temporary files.

  If your installation has failed or the installation does not remove the folder to the random name when it finishes running again installation will be another folder at the random name.

  You may be able to identify installation (out of curiosity) by looking at some of the contents of the folder and decide if this installation was not serious, just remove the files/folders.  If the installation does not work for some reason, run again just installation will create a new temporary folder to the random name so the old temporary folder is really useless.

  Records are sometimes tough to remove.  Even if you are an administrator on the system, you might get a "sharing violation", "access denied", "used" or type similar message when you try to delete temporary folders.  Facilities sometimes use different permissions that can have a regular user with the administrator group.

  There are many methods to try to remove the folders, and some require third party programs to install or change some windows settings that could compromise the security of your system if you do not change them back when you're done.

  Start your system in Mode safe mode (by pressing the F8 key several times just before XP attempts to load) is one good method to try to remove the files because it does not have to make any changes to your system configuration or by downloading third-party programs.

  If you are running XP Home Edition, the following section on turn off "Simple file sharing" does not apply to you since in XP Home, Simple file sharing is always turned on.  If you are running XP Home Edition, skip the next few paragraphs and resume where it says:

  "If no part tool above work try a third popular called Unlocker.

  If Safe Mode does not work you can change the security of the folder when you start in Normal Mode to give your username full control over the files by navigating to it in Solution Explorer, click on tools, Folder Options, view and in the advanced settings window, uncheck (at the bottom of the list) use simple file sharing (recommended) and click OK.  This disables him recommended simple file sharing on your computer if you want to turn it back on when you're done to make everything you do.

  Right-click on the files of interest, click Properties and click the now visible security tab.  Change the properties, but you need (for example, select your user name, and check the box to allow full control), click OK to apply the changes.

  With usage share of active simple files (recommended) the checked the properties of the folder tabs are:

  General, sharing, customize

  With the use of sharing files simple disabled (recommended) box unchecked, the properties of the folder tabs are:

  General, security, customize

  Now, try to manipulate/delete the folder.

  It's a good idea to go back to the Explorer and the cheque in the box easy to use sharing files (recommended) when you have finished making everything you do.

  If none of the above works, try a popular third-party tool called Unlocker.

  Unlocker can be downloaded here:

  http://www.emptyloop.com/Unlocker/

  If you use Unlocker, be sure to install because he wants to add a bunch of options, addons, shortcuts and other extras that you don't need.

  You must add the shell extension so when you right click on the offending file, you will have a Unlocker option to choose.  I would just install it long enough to clean up the leftovers and then, I usually just uninstall and all parts of it.  You can always install it again another day if you like.

  Unlocker can be uninstalled when you have finished using it.

  Reboot when finished to ensure that boring records are really missing.

• WLC4402 - Questions to upgrade the AP and controller

  Hello

  I just upgraded an AIR-WLC4402-12-K9 to version 7.0.98.0 of the software, and I have a few questions-

  1. I have no APs to connect yet but when I do I'll have to check what software they run and perhaps demote the controller to get access up to v7 points?  To join the WLC v7 since v3.2 I had to make a few intermediate upgrades and I wonder if I have been a little premature and should have done updates after the APs have been associated, has new software pushed from the controller and then performed the steps in upgrade of WLC so the WLC and APs were synchronized in terms of software.

  2 - the memory usage is sitting at 60% with no associated APs.  I have just connected 4402-12 running 5.1.151.0 and he's sitting at 33% use of memory with associated access 11 points.  Have I spent in a too recent version for this controller?  What is a figure of the memory use of a 4402?

  Thanks in advance,

  Jason.

  Jason,

  A question.  You should be fine.  When the AP detects the WLC, it will do a code audit.  If this isn't the right code, it can extract the correct image of the WLC.  As long as the AP you are supported in 7.0, the recovery on the access point image won't matter.

  For question 2.  sounds of 60% of normal for 7.0, depending on the amount of memory is on the device itself.  I woulnd't ' t be too concerned about the memory usage until you points upward in the high 80 years.

  See you soon,.

• Comparison of the results of the performance and the sum of the sum of array elements

  I did a comparison of the performance of "Add table" with 2 other methods (an Add elements and function of ddot BLAS) to see who was the fastest and also to compare their results, given that I was watching a few slight differences.

  Conclusions
  BLAS ddot's quicker (just a little), then add items, then add it in a loop of table

  BLAS ddot and add items table give identical results almost all the time.

  I don't know why add items in a loop manually gives a slightly different result. I understand there are any rounding due to finite precision errors, but why is it different for the 2 other methods?

  This classic of digital computing: the quality of the result depends on the order of operations.

  A simple example is the calculation of a * b / c with a, b, c equal to 25, 200 and 100 respectively. The result should be 50, but if a, b and c are U8, the result depends on the order of operation, as shown in the example below. DBL and data non-entier, the difference is of course that much smaller, but still there are!

  

  

  In your case, the difference also stems from the order of operations:

  -in the table add-in, the product of all the elements is calculated first and then the elements of the array are added.

  -in the loop, the addition is performed after each multiplication.

  I could not optimize this query for best performance and optimized the cost... Can someone guide me on this.

  Thank you

  You think you're going to lines updates 85K, Oracle think it will update a line.

  At the time where the existence of the first test runs that oracle think already up to 49 lines, which is probably why he uses the loop join nested for the second test. (In your version of Oracle, the subquery introduced existence a very bad assumption (small) on the amount of data will survive).

  It is possible that you will get better performance if you hint Oracle using a hash join for testing the existence - and you might want to think what test will eliminate most of the data and that we can first force.

  Having said that, however, note that MMR_DTL research is a considerable fraction of the cost of the query - and an analysis is an easy thing for Oracle cost properly - if, despite your comments on update a column with a clue to this topic, you will find that the query can be more effective if you use an index. This is more likely to be the case if data ' WHERE CAPITN_PRCS_IND = 5 AND HSPC_IND = 'Y' "is well grouped (perhaps the latest data added to the table).". "  You could then reduce the cost of maintaining this index by creating an index based on a feature that indexes only the lines where the predicate are both true so that the 2 update deletes the index entries and allows the index remain as thin as possible.

• The similarity is the performance and tuning 1z1-064 (12 c) the exam 1z0-054 (11g)?

  I had Oracle 11 g performance and Tuning of Oracle class.

  I wonder how close the 1z1-064 will be the exam 1z0-054.

  I'm also a student at the exam 1z1-064.

  Is he still released books, or simply the material of the RTO.

  Thank you Roger

  Oh - and regarding the materials on 1Z0 - 064, there is not yet any material of third parties specific to 1Z0 -054 out right now.  I am sure that there is no output for 064 yet.  I will create a guide for it shortly... I hope that I will be able to complete before the beta and take the exam at the end of the beta.  However, I concentrate on my exams to practice at the moment... so I don't even know if I'll make this deadline.  I certainly will not post before the end of the beta review and probably not until the review of the production is released.

• my apple mac shows a symbol of folder with a question mark on the screen and beeps

  My apple imac seems that having frozen with a white screen, a folder symbol flashes on and off the screen, file symbol has an exclamation mark on this subject, the computer has a beep but has now ceased, any idea on what is the problem and how to solve?

  What to do with all these "beeps mean at the start? - http://forum.insanelymac.com/lofiversion/index.php/t62919.html

  Power on self-test beep definition - part 2 - http://support.apple.com/kb/HT1547 - old Macs

  Mac Power on Self Test RAM Intel processor error codes - http://support.apple.com/kb/HT2341

  iMac (mid 2007) and later models: on startup tones - http://support.apple.com/kb/HT2538

  Flashing?  Means the computer cannot find a valid boot disk.

• Questions about the performance and discs

  Specifications of the computer:
  ASUS P6X58D Premium Mainboard
  Intel Core i7 930 (no decree with Zalman 10 X Flex cpu cooler)
  12 GB (six 2 GB) Kingston PC3 10600
  PSU Antec CP - 1000 1000 watt
  NVIDIA GeForce GTX 480 video card
  Card RAID Areca ARC - 1680IX - 12 PCIe x 8 SAS
  (hard drives listed below)
  Windows 7 Pro 64-bit, with many system applied settings (no antivirus loaded into the machine.
  No startup process all active.)
  Adobe Production Suite (enabled in PPro CS5, update 5.02 MPE) installed
  Latest Nvidia drivers installed.

  Blackmagic Disk Speed Test

  (system disk) Two Intel X25M MLC GEN 2 80 GB SSD drives in a striped RAID 0 array.
  read: 501.0 MB/s write: 130,9 Mbps

  (disk storage) 2 a to 2 WD 7200 RPM 32 MB SATA hard drive.
  read: 117,0 MB/s write: 118.4 MB/s

  (project reader) Three WD black 1 TB X 6 GB/s 64 MB of cache disks in RAID 5 array.
  read: 211,9 MB/s write: 215,3 Mbps

  These moments of read/write comparative look correct?

  Video editing:

  DV (720 x 480) 48 hz audio 30 fps 3.6 MB/s
  4 layers
  Layer 1-100% opacity, applied Cineon converter
  2 - layer 50% opacity, vertical flipping applied
  Layer 3 - 30% opacity, applied color balance filter
  Layer 4 - 20% opacity, filter contrast applied
  read the full resolution
  IN TIME REAL
  CPU utilization - 25% (I knew performance DV would be awesome.) I could have added more layers but stopped at 4)

  AVCHD (1920 x 1080) 48 hz audio 60 fps 3,1 MB/s
  2 layers
  Layer 1-100% opacity, filter contrast applied
  Layer 2-50% opacity, vertical flip
  reading of the resolution 1/4th
  Real-time
  CPU utilization - 98-99% these specifications of reading straight look? The GPU is doing its part to work? I guess that my GTX 480 is positioned in the right slot?

  Question: The cards need fast RAID when the flow of AVCHD is 3. 2 MB/s?    ?
  

  I find it interesting that I spent $4K on a computer and I only make 2 layers of AVCHD in real-time (from reading of resolution 1/4). I am aware that my provider built computer is more expensive, but in return, I will say it is surprisingly quiet.  :-)
  

  Should I wait for performance significantly more when I switch to the 980 x cpu and 24 GB of RAM? Maybe I owe OC my processor for best results, but I have neither the time nor the inclination to teach myself overclocking. (Anyone know of a person in the Phoenix area, AZ, who is skilled at overclocking)? I did not test PPBM5 I just want to get better performance for what I paid. Maybe my expectations are wrong?
  

  I suggest that update you with the version of StorPort that is the improved version of the driver technology Microsoft.  SCSIport is what has been used for Windows XP.
