We are trying to shrink a partition on a brand new computer with 1TB of
space (2 x 500GB RAID-0). The hard disks came partitioned as only one drive
. However, when we attempt to shrink the drive it will only let us
shrink the drive to about 400GB, even though the disk is barely used (only
20 GB used). The 'Disk Management' help ndicates that this can be due to
the fact that the unmovable Windows Vista page file is limiting how much we
can shrink the partition. To overcome this problem the help suggests we
move the page file to another disk, delete the stored shadow copies, and
move the page file back to the original drive.
Unfortunately, there are no detailed instructions on how to accomplish these
tasks. We have found that the 'Advanced System Settings' in the computer
'Properties' dialog, appears to have options for allowing us to move the
page files to another disk, but how do we manually identify and delete any
stored shadow copies?
For your convenience here is a quote of the help section:
When you shrink a partition, unmovable files (for example, the page file or
the shadow copy storage area) are not automatically relocated and you can
not decrease the allocated space beyond the point where the unmovable files
are located. If you need to shrink the partition further, move the page file
to another disk, delete the stored shadow copies, shrink the volume, and
then move the page file back to the disk.
