By shrinking the Windows volume, you can free up enough space to create a new partition that can be used to dual boot into linux. Now lets say after trying linux, you decide its not for you. Now you are left with all this leftover space that is not being used by Windows. To reuse this space, you simply need to expand, or extend as Vista calls it, an existing Windows volume so that it uses all the available free space that was previously being used by linux.
When resizing volumes in Windows Vista, Windows 7, and Windows 8 you must be aware of the following criteria:
You only have the ability to shrink or expand NTFS or RAW (unformatted) partitions using Windows Vista tools.
When you shrink a partition, unmovable files such as a page file or a shadow copy storage area are not relocated. Therefore you cannot decrease the size of the Windows volume beyond where these types of files are located. If you need to further shrink the volume, you will need to remove, move, or delete the page file or shadow copy storage area first, then shrink the volume, and then add the page file or shadow copy storage area back to the drive.
If enough bad clusters are found on the disk the partition will not be allowed to shrink.
You must be logged into an Administrator account in order to resize Windows Volumes in Vista.
Windows XP Disk Management bases the cluster size on the size of the volume. Windows XP uses default values if you format a volume as NTFS
Why change cluster size?
Cluster is an allocation unit. If you create file lets say 1 byte in size, at least one cluster should be allocated on FAT file system. On NTFS if file is small enough, it can be stored in MFT record itself without using additional clusters. When file grows beyond the cluster boundary, another cluster is allocated. It means that the bigger the cluster size, the more disk space is wasted, however, the performance is better. However, when you format the partition manually, you can specify cluster size 512 bytes, 1 KB, 2 KB, 4 KB, 8 KB, 16 KB, 32 KB, 64 KB in the format dialog box or as a parameter to the command line FORMAT utility. What it gives us? Determine average file size and format the partition accordingly
The default cluster size on NTFS volumes is 4K, which is fine if your files are typically small and generally remain the same size. But if your files are generally much larger or tend to grow over time as applications modify them, try increasing the cluster size on your drives to 16K or even 32K to compensate. That will reduce the amount of space you are wasting on your drives and will allow files to open slightly faster.
Two caveats, though:
The second caveat means that you should also
All file systems that are used by Windows organize your hard disk based on cluster size (also known as allocation unit size). Cluster size represents the smallest amount of disk space that can be used to hold a file. When file sizes do not come out to an even multiple of the cluster size, additional space must be used to hold the file (up to the next multiple of the cluster size). On the typical hard disk partition, the average amount of space that is lost in this manner can be calculated by using the equation (cluster size)/2 * (number of files).
thnx Tariq bhai
kia cs609 kisi ka subject ni he???
My opinion is, The all file systems that Windows XP uses to organize the hard disk are based on cluster allocation unit size, which represents the smallest amount of disk space that can be allocated to hold a file. The smaller the cluster size, and the more efficiently your disk stores information.
If you don't specify a cluster size for formatting, Windows XP Disk Management bases the cluster size on the size of the volume. Windows XP uses default values if you format a volume as NTFS by either of the following methods.
first method is: By using the format command from the command line without specifying a cluster size.
2nd method is: By formatting a volume in Disk Management without changing the Allocation Unit Size from Default in the Format dialog box.
anyone tell me, i am right/wrong...
what is your opinion "yes" or "no"
as per information. You are right. But according to GDB, you are wrong. Because You did not support 'Yes' or 'N0'.
You need to support Yes or No. No need to give detail.
Increase in NTFS cluster size will not decrease the volume size.
