|
Writing to disk can cause file fragmentation over time. Third party
|
|
defragmentation programs such as Norton Speedisk, PCtools Compress, and
|
|
VOPT can remedy this condition on uncompressed drives, but should NOT be
|
|
run on STACKER drives.
|
|
|
|
Q: Why can't I run third party Defragmenters on a STACKER drive?
|
|
A: STACKER's special method of storing compressed data cannot be
|
|
interpreted by these programs. If run on a STACKER drive, they can
|
|
actually increase fragmentation. It is O.K. to run third party
|
|
defragmenters on the noncompressed drive.
|
|
|
|
Q: How do I defragment a STACKER drive?
|
|
A: Stacker version 2.0 includes a defragmentation utility called SDEFRAG. It
|
|
is specifically designed to defragment STACKER drives. It will not
|
|
defragment a noncompressed drive. To defragment a STACKER version 1.x
|
|
drive, it is necessary to back up the data on the drive, delete the data
|
|
on the drive, then restore from the backup. A recommended alternative is
|
|
to upgrade to STACKER 2.0 and use SDEFRAG .
|
|
|
|
Q: What if I accidently ran a third party defragmenter on a STACKER drive?
|
|
A: Your data remains safe, however, the fragmentation may have been
|
|
increased. Run SCHECK /f to correct any errors on the drive. Then run
|
|
SDEFRAG to defragment the drive.
