• What are the size of partition recommended for installing Windows 7 Professional 64-bit?

  What are the size of partition recommended for installing Windows 7 Professional 64-bit? I have a 2 TB internal hard drive and want to install Windows and Norton Internet Security on the drive C, drive D and drive E data programs.

  Thanks for a response.

  Original title: size partition Windows 7 Professional 64 bit

  For technical purposes, I recommend you only keep utilities all programs that you install on the startup disk. This is recommended if you plan to upgrade to future releases of Windows such as Windows 8 because you will experience problems with the installation program.

  I recommend however, you can keep accumulated data such as Documents, Photos, music, videos on a separate partition to ensure custody.

  The recommended size for the boot drive around things like Windows, future growth for applications and the Windows updates and program updates will be considered.

  So I recommend not more than 200 GB, for a lot of space, I would shoot up to 300 if you want to keep things like System Restore Points.

• Partitions ESX 4.0

  I have a two part question.

  I am trying to create a new ESX server 4.0.1. What are the sizes of partition recommended for

  / ROOT

  / SWAP

  / VAR

  / OPT

  / TMP

  / HOME

  / USR

  I have two drives of 73G mirrored for the ESX Server.

  Second part of my question is about how the disks are partitioned in the examples I found. Why are the discs partioned as follows

  ext3/var 4096 MB

  ext3/tmp 1024Mo

  / opt ext3 2048 MB

  instead of simply

  ext3/var 4000 MB

  ext3/tmp 1000 MB

  / opt ext3 2000 MB

  Here is a shot of our kickstart of how us disperse with two 72-GB drives mirrored.

• Recommend disk utility to resize system partition?

  I want to thank my C partition to include the unallocated space that allowed to remove my recovery partition.  DISKPART in windows doesn't allow me to do.  Can anyone recommend a management utility disk that will do that without endangering my OS and files or including malware, etc. ?  Thank you.

  I found a free disk with a note management utility high on download.cnet called Easeus Partition Master - it worked very well - quick and easy.

• Rearranging Drive C - can recommend Vista management computer or maybe third-party software such as the Partition Wizard.

  original title: reorganize the C drive

  I am very short of space on drive C (system disk).   I've been advised to rearrange the drive C partition, as I have a lot of space on the D drive.   What is the best way to do this without losing any data on C or by altering the system?   Can anyone recommend Vista management computer or maybe third-party software such as the Partition Wizard.

  Hello

  read this topic to regain free space on C:

  see if this program helps you to determine what is take up space

  http://www.Jam-software.com/treesize_personal/

  by default system restore will have up to 15% of the capacity of the hard disk

  you would like to reduce this amount

  http://www.Vistax64.com/tutorials/76227-system-restore-disk-space.html

  http://www.vista4beginners.com/system-restore-space-used

  also use disk cleanup

  also scan for malware

  Download update and scan with the free version of malwarebytes anti-malware

  http://www.Malwarebytes.org/MBAM.php

  and read these information from microsoft on windows optimization

  http://Windows.Microsoft.com/en-us/Windows-Vista/optimize-Windows-Vista-for-better-performance

  and using vista disk management you need to delete D: and extend C: into the unallocated space where D: is

  You can't fire a piece of D: on C: using vista DM

  Save all data, because it will be lost on D: and make sure that D: is not your recovery partition

• Partition Linux Config recommended

  I'm sure it exists, but I can't find it anywhere.  Is there a guide of best practices for how to configure your Linux partitions for installing Oracle 11 GR 2 (not ASM)?  For example, I guess everything (executable, far, data, etc.) on a partition is probably not optimal?

  It depends on.

• Recommendations for "Standby" host / creation of an additional data store / system partition

  My ESXI host 5.0, as well as several virtual machines in the data store, resides on a drive of 500 GB of aging.

  I have a disc of 2 TB to spare I would partition to as a standby host and an another data store containing the virtual machine, whose thinking is that when the 500 GB drive goes down, I can boot from the 2 TB drive and the new.

  I'm looking for suggestions for the best option to implement.  Thoughts include:

  1. A new installation of ESXI on 2 TB drive and restore the configuration from a backup "vicfg-cfgbackup" of the host of 500 GB
     1. have two partitions VFMS, one, a "backup" of the current data store containing the VM on the 500 GB drive and the second is a "general" datastore ~1.5TB that I can use for a volume of FreeNAS; or,
     2. have a bigger VMFS partition
  2. Partition my drive from 2 TB to allow later installation of ESXI; and two partitions VFMS (one of the same size as on the 500 GB drive and the second using the remaining space available), or a single VMFS partition

  Proceed to option (1) would result in two disks with ESXI hosts on a machine, but probably, because they are not clones, the UUID must be different so there is no problems with the discs being active.  I just need to set the BIOS to boot from the correct disk.  I understood this correctly, and if so, are there other potential problems with this approach?  The process of installing ESXI allows multiple VMFS created on the a drive, or this work manually through the command line interface, or the vSphere client

  The second approach is possible, and would I partition the same drive the 500 GB (IE several partitions of LinuxNative, a systemPartition, a vmkDiagnostic and a vmfs partition), with an additional partition VFMS (or a large VMFS partition)?  Or is it not possible to install ESXI on a disk with partitions that must be kept.  From what I've seen, it seems that if the Setup program detects that the drive has [a] [s] of data store, then the option is provided for the upgrade, so maybe it's possible to install ESXI on a disc with pone or warehouses of VMFS more data on the disk...

  Or maybe there is a third option that would be best.

  Any advice?

  Hi Ray,

  If you have just a 500 GB drive in your host 5.0 store the ESXi and your VMX/VMDK virtual machines then why not just do the following.

  1. Remove the 500 GB drive
  2. Insert the 2 TB drive
  3. Install ESXi 5.5U2 (or 5.0, if you still need a compatibility it provides) and partition your drive from 2 TB to choose from including data storage you want.
  4. Turn off and add the 500 GB drive (or place it in a networked PC or in a basket usb)
  5. Power and copy the vmx/vmdk files of the 500 GB to your new store of data and add virtual machines to the inventory
  6. Now periodically instant and take backups of your virtual machines to your 500 GB drive (by placing it in a USB port or network caddy/PC)

  What's an option 3?

• VMFS partition alignment and recommendation of the storage provider

  In the literature of my storage provider it says they use a band of 256 KB size, and it's a good approach to set the offset to 256 KB (or 512 sectors) when creating VMFS volumes.

  "When you use the VI Client, the new partition is automatically set to an offset of 128 sectors = 64 k." But,
  in fact, this configuration is not ideal when you are using the DS8000 storage disk. Because the
  DS8000 uses more large block sizes, the offset must be set to at least the size of the stripe. For
  RAID 5 and RAID 10 in the attachments of open systems, the allocation size is 256 KB, and it's a good
  approach to set the offset to 256 KB (or 512 sectors). You can configure individual compensation
  that from the ESX/ESXi server command line. »

  I'm guessing that they always use the old VMFS3 information above?

  Now with vSphere 5.x and VMFS5 the offset is to the sector 2048 (or 1024KB)

  Question is if I go with vSphere 5.x VMFS5 and create the volume VMFS via vCenter VI Client will be I'm always perfectly aligned with my storage or should I still manually create VMFS volumes with starting with sector 512 (256 KB)?

  Thank you for your answers!

  1 024 KB alignment is a multiple of many sizes of block by default if it guarantees a correct alignment for all types of storage where the result of 1024 / 'stripe size' is an integer value.

• ESX host with local storage recommended for the host partition table?

  Hi all

  I know that the best practical partition table should look like this:

  Mount Point	Partition	Size	Description
  		/ dev/sda (primary)
  / Boot	ext3	250 MB	Change of extra space for upgrades
  N/A	SWAP	1 600 MB	Change the maximum size of Exchange service console
  /	ext3	5120 MB	Change of extra space in the root
  		/ dev/sda (Extended)
  / var	ext3	4096 MB	Create partition to avoid an overflow of root with log files
  / tmp	ext3	1024 MB	Create partition to avoid an overflow of root with temporary files
  / opt	ext3	2048 MB	Create partition to avoid overfilling root with the log files of VMware HA
  / Home	ext3	1024 MB	Create partition to avoid an overflow of root with agent / user files
  	vmkcore	100 MB	Pre-configured

  However with a system with local storage would you set it up the same way, and whatever it is must be amended to change to get ESX to write log files to the different partitions?  I would like to configure it for future expansion for when the enterprise package is configured.

  Yes, I would set up the same way with an ESX with local storage server and nothing needs to be changed for the vmekernel right at the partition/var - unless of course you want to write to a log server that you need to change a configuration file to point to the server logs.  If you talk to the ESX Enterprise license you willnot have to change partiition table-

  Also on something else if you don't have a SAN/NAS storage you will also need to create a VMFS partition on the local data store to host your virtual machines

  If you find this or any other answer useful please consider awarding points marking the answer correct or useful

• Cannot start after the formatted NTFS partition

  Option to boot OS X suddenly absent after that I formatted the partition NTFS (bootcamp) of Windows installation.

  

  I read many previous question in many Web site and

  I tried to fix it in disk utility, but it cannot go up more.

  user mode single launch I tried, but it does not start.

  already reset NVRAM and SMC.

  Is there not any solution to start again or access my files in the partition mac to back up?

  Thank you.

  Somehow, you managed to format your OS X with making it unusable NTFS volume. I recommend you do the following:

  Clean Install of El Capitan

  Restart the computer. Immediately after the chime, press Command + Option + R until a globe appears.

  The Utility Menu appears in 5 to 20 minutes. Be patient.

  Select disk utility, then click on the continue button.

  When loading disk utility, select the drive (generally, the entry Out-bumpy) in the list aside.

  Click the Partition tab in the main window of disk utility. A panel will fall.

  Set the GUID partition scheme.

  Define the type of Format Mac OS extended (journaled).

  Click on the apply button, then click the fact when it is active.

  Quit disk utility and re-enter the Utility Menu.

  Select reinstall OS X and click on the continue button.

  This should install it the version of Mac OS X that has been previously installed when the computer was new.

• Partition missing after restoring from Time Machine

  Hello world

  I use an iMac 27-inch mid-2010 and have a WD1230 external 2 TB disk attached to it. I partitioned the external hard drive to allocate 1 TB as a Time Machine backup repository and the other 1 to to put in music, movies and images files to save space on my system aging 1 TB drive.

  Good thing I put up this way because one day my system comes to refuse to start. I went in the mode utility and used the Time Machine restore feature to help me get back on my feet. After a restoration of 18 hours, the system is now purrs with all files and settings affected. Bravo for the process of Time Machine!

  However, this is the number I noticed during the restoration, formatted system partition on my external drive labeled "STORAGE" which contained my music and movies. I know that the files are there but I need to know how to access these files again as the STORAGE drive is so more appear in the Finder. I did a scan Disk Utility on the hard drive external with no luck either. Can anyone who has gone through this similar situation help out me? Thank you very much in advance!

  Restore using Time Machine to copy a game on the disc that you point to backup. It performs no operations on any drive or partition other than the one to which it is to copy the files. If Time Machine, neither utility restore formatted or partitioned external hard drive (unless it is more what you're saying.)

  It may be possible to recover lost files from this drive using a disk utility such as restore data of Prosoft. As a former tech, it's my go to software. There is no guarantee that it will work. Dril drivel is another recovery program people I know recommend but I never used it.

  Is there a way to fix this?

  MiniTool is not recommended because it causes problems and can lead to data loss.

  OS X Terminal please after the release of the following OS X Terminal commands. Enter your password when you are prompted by the command 'sudo '.

  diskutil list

  Cs diskutil list

  sudo TPG - vv - r see the/dev/disk0

  sudo fdisk/dev/disk0

  Do not change the partitioning information any more, otherwise, you will lose your Windows data permanently.

  How to partition your hard drive or SSD

  In disk utility, select the internal drive of your Mac, making sure to click on the drive and not the volume below. You should see two tabs under the tool bar: first aid and Partition. Click on the Partition.

  Click on the '+' below the route of the wall to add a new partition on the drive. You will see the layout changes to display the extra partition. You can now change the size of the partitions by moving the line dividing the worms upwards or downwards, subject to a minimum size for the boot partition which is based on data that currently stored on it. When you did the size you want them, click the new partition and type a name in the "name:" box. Make sure that the format is Mac OS X extended (journaled).

  Once you have defined the size of the partition and named the new partition, click on apply to finalize everything. Alternatively, if you change your mind or you want to start, click on back to the Plaza.

  The main drive of your Mac is now split into two volumes, with the new a vacuum. You can now install another version of Mac OS X on it, use it to install a beta version of Mac OS, or keep as a place to store data.

  I'd go with recommendation of Apple in the Mac world.

  Mac World was busy to legitimize Mac Paw when the community in its whole understood paw sold con-artist-ware so that they are out of my list of trust article.

  Disk utility (El Capitan): partitioning a physical disk

• Cannot turn on FileVault 2: "some disc formats do not support the recovery partition" version of the OS - 10.11.4

  Hello

  I went to turn on FileVault encryption for the first time, and when I click on restart (by FileVault guests) I got a error message that says "FileVault can not be enabled for the drive. Some disc formats do not support the required encryption recovery partition. To use encryption, reinstall this version of Mac OS x on a reformatted drive. »

  I found an article from apple support for this problem with El Capitan who recommended first aid running in disk utility.  I tried this but then received the same error message.

  a little history:

  -Mac OS 10.11.4 installed running on the brand/model ADATA SP 550 SSD

  -This SSD is a 250 GB drive partitioned into two, with one of these partitions being my OS

  -J' ran this BONE of a Bay external thunderbolt

  -ssd is formatted as HFS journaling +.

  I am really confused about this error message and couldn't find much online about it.  I use a fairly recent OS install.  I installed the operating system clean and made all my preferences and install so that I can encrypt and then back up this pristine OS environment in time machine so that I could always go back to it on the line in case where things are bunk too upward.  I'd have to install yet another OS to clean and do all my long software installs and system preferences settings... SIP.  I don't know if that makes a difference, but this version of the OS that I have been cloned by superduper to this SSD partition.

  What is the brand of SSD that I?  Might that matter?  I appreciate all the comments.  I'm really scratching my head...

  Thank you very much

  To enable FileVault, you need a recovery partition, which you don't have. You can create one by reinstalling OS X.

  If you do not already have a current backup, please backup all data, and then reinstall the OS. * you don't need to erase the boot volume, and you won't need the backup unless something is wrong. If the system has been upgraded an earlier version of Mac OS X, you may need to the Apple ID and password to use.

  There are ways to back up a computer that is not fully functional. Ask if you need advice.

  If you installed the runtime Java distributed by Apple, and still need, you will need to reinstall it. It goes the same for Xcode. All other data will be preserved.

  Related support article refers to OS X 10.11 ("El Capitan"), but the procedure is the same for OS X 10.7 ("Lion") and later versions.

  How can I perform a clean installation of Mac OS x for my iMAC, retina 5K late 2014 with drive of Fusion with the intact Recovery HD partition?

  Pure how to install OSX on a Fusion drive and keep the recovery disc function

  These instructions assume that your iMAC partitions or file systems has been damaged and you want to restore to the way most efficiency with fusion drive and the recovery partition, similar to what was built in the factory.

  These instructions work for the iMAC, retina 5K end 2014 version comes with OSX Yosemite. The scores of major drive of the 128 G SSD and 3 TB of HARD drive has been configured as a logical drive (merger by car).

  WARNING: These instructions here are shared for interest only. Readers to take their own risk by following these instructions. The author is not responsible for any damage caused by following these instructions.

  This is the target disk partitions, and the configuration that we want to achieve.

  Disk0 is the 128 GB SSD - solid state drive and holds the start of the partition (disk0s3)

  Disk1 is the 3.0 to HDD - mechanical transmission and holds the Recovery HD partition.

  There are two EFI partitions to partition table GUID on both hard drives (disk0s1, disk1s1).

  Disk space remaining (partition disk0s2 and disk1s2) are used to create the disc of Fusion 3.1 to named "Macintosh HD".

  / dev/disk0 (internal, physical):

  Fusion unencrypted drive

  Here's how we do it.

  • A. clean reinstallation of Mac OS x.
  • 1. make sure that you back up all your data on the hard drive using Time Machine or other means. The following procedure will delete all data.
  • 2. create the OSX install USB, insert it to the MAC workstation.
  • 3. given that us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 4. in the menu at the top of the screen, select disk utilities.
  • 5. turn highlighted the volume of disk Fusion called "Macintosh HD." Click clear to clean.
  • 6. If his success, then go ahead to install OSX new to that partition, as usual.
  • 7. otherwise, if it does not, that means fusion drive has been damaged.
  • 8 follow the instructions below to fix it.
  • . B. Split disc Fusion in the physical hard disks
  • 1. Since us will be operated on the internal drive of the Mac trunk, assumes that we already have boot up OSX install USB drive (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3. on the screen of the terminal type:
  • Cs diskutil list.
  • You will see something similar to the screen below.
  • 4 copy the long string after Logical Volume and replace the UUID with it in the following command to delete the logical volume of the disc fusion (aka coreStorage of logical volume):
  • diskutil deletevolume cs UUID
  • For example:
  • diskutil deletevolume E59B5A99-F8C1-461A-AE54-6EC11B095161 cs
  • 5 copy the long string after the logical volume group and replace the UUID with it in the following command to remove the drive (aka coreStorage) fusion:
  • diskutil cs remove UUID
  • p. ex. diskutil cs remove E03B3F30-6A1B-4DCD-9E14-5E927BC3F5DC
  • 6. at this stage, the fusion drive has been deleted, and hardsisk SSD and mechanical hard drive will be reappear in diskutil or separate records.
  • 7. If step 5 or 6 takes more than 30 minutes to complete, this means that the fusion drive has been corrupted. You can follow the commands below to clear the table to partition the hard way. First command clears the SSD drive, second command erases the HARD drive.
  • The command does not return a response, after 1 minute, press Ctrl + Z to complete orders. 1 minute is enough data to code and erase the partition table on the disk.
  • cat/etc/random >/dev/disk0
  • cat/etc/random >/dev/disk1
  • . C install a new copy of Mac OS x for the hard drive HDD and tested this disk partition hard recovery work.
  • 1. go on diskutil to create a partition called Macintosh HD HDD hard drive using all the space there.
  • 2 do the same with the mechanical hard drive.
  • 3. follow the usual procedure to boot from the installation of OSX USB and install a new copy of Mac OS x hard disk SSD.
  • 4. This will create the correct priming of the partitions, recovery hard drive partitions and PSX partitions hard disk HDD.
  • 5. once the installation is complete, test if OSX may start successfully, but no need to go through the initial MAC OS x didn't put in place that we're going to waste this and do the installation again later.
  • 6. we must now test if the recovery hard drive partition works.
  • 7. reboot for hard drive recovery (see X - by pressing command and R at the same time during boot right after that you hear sound start and release only a few seconds after you see the apple logo and the progress bar for loading...)
  • 8. it is important to test and make sure that the partition of hard drive recovery.
  • D. recreate the fusion drive
  • 1 since us will be operated on the internal trunk of the reader of the Mac, it must start on OSX install USB (see Y.).
  • 2. in the menu at the top of the screen, select utilities and Terminal.
  • 3
  . on the screen of the terminal type:
• diskutil list.
• You should find that we have a list of disk group hard physical volume only, no logic here still.
• 4. you will see something similar to the screen below.
• 5. search for the largest partition on the SSD hard drive, which should be close to the maximum size of HDD to the SSD (121 G, for example) and mark the name of the device, this will usually be something like/dev/disk0s2
• 6. search the largest disk partition mechanical forming fusion with the SSD hard drive. This should be close to the maximum size of the mechanical hard drive (for example 3 TB) hard disk and mark the name of the device, this will usually be something like/dev/disk1s2
• 7
. Now let's create the merger in car (group alias logical volume) in the Terminal, type: diskutil cs create nom_lecteur driveIDs
• The number of the driveIDs is unlimited, it may be a number of discs, or a number of disk partitions. Always put the faster discs first, for example for our SSD disk0s2
• For example:
• diskutil cs create fusiondrive disk0s2 disk1s2
• diskutil - the version of disk utility command line.
  cs - This calls for Core Storage, which is necessary for the merger.
  create - creates a basic storage group.
  nom_lecteur - is the name of the drive and how you want that he
• appear in the disk utility (not the Finder - that comes later). You can call it what you like; in our example, we named our Fusion table "Fusion".

driveIDs - Here is the Player IDs of the readers you want as part of your Fusion table, separated by a space. In our example, they are 'disk0' and 'disk1', but it may be different in your configuration.
• It is important that the faster hard drive appears first in the command, which in our case the disk0s2 (a partition in the SSD). In this way, drive fusion will use this disk as primary and the cache. The second disc in the command, in this case disk1s2 (a partition on the HARD disk). The secondary disk (HARD drive) is used to store less frequently used files.  Otherwise, the fusion drive performance will be worse that it is designed for.
• 8. you will see something like below appear on the screen:
• Creation Volume logical storage of kernel
• Move isk0s2 storage of carrots
• Disk1s2 of switching for the storage of carrots
• Waiting for logical volume group appear
• Discovered the new group of logical volumes 'DBFEB690-107B-4EA6-905B-2971D10F5B53 '.
• Store LVG UUID: DBFEB690-107B-4EA6-905B-2971D10F5B53
• Finished CoreStorage operation
• 9 copy to the bottom of the string after "Discovering new Volume Logic Group" using the command + C
• 10. next, create the partition of the merger (alias logical volume) drive named "Macintosh HD".
• In the Terminal, type: diskutil createVolume groupString jhfs cs + size volumeName
• For example:
• Diskutil createVolume DBFEB690-107B-4EA6-905B-2971D10F5B53 jhfs cs + 'Macintosh HD' 100%
• diskutil - once again, this is the version of disk utility command line.
• cs - called the basic storage functions, which are necessary for this arrangement.
• createVolume - this is the command to create the storage area real for the reader who is represented by an icon on your desktop.
• groupstring - this is the long alphanumeric string you copied in the previous step. It identifies the table you created such as getting a volume placed on it.
• jhfs + -the format of the disc. It is Apple (journaled) extended Format, which is recommended for drives with an operating system installed on it.
