- WORD OF WARNING!!!!!
-
- Make sure your DOS defragmenter copies the ENTIRE file entry from the FAT
- table to it's new position. OS/2 uses some reserved areas from the DOS header
- (table entry, not file header) to keep the extended attributes on FAT systems
- and some defraggers do not copy this data.
-
- Call the software manufacturer if you are not sure and make sure to make a
- complete backup before defragmenting.

-
- I don't think HPFS defrags itself, its algorithm just makes it more resistant
- to fragmentation.
