- 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.
