I am desperately seeking sources for a program to defragment my hard disk.
Due to a lot of files coming and going, I am left with many files broken
into small pieces and scattered throughout the disk.
While I have seen this facility provided with some of the larger Unix
systems, I haven't seen such for smaller systems. (I am running
386/ix 2.0.2, a SysV.3.2 derivative.)
Any pointers to either a PD or commercial product would be greatly
appreciated.
Thanks in advance.

On some systems, such as SCO Xenix, an approach such as the following has the effect of defragmenting file systems. (a) backup up the file system you want to defragment (or at least major directory trees in that system); (b) verify the backup; (c) remove the backed up files; (d) fsck -s (e) restore from the back up.

A faster alternative to steps c and d is mkfs. This will have the effect of removing all files and rebuilding the free list and it runs a lot faster than "rm -fr *" for full file systems. When using fsck or mkfs to build a free list, be sure you have reasonable vaules for the gap and blocks/cyl. Don't let them default; they really do make a difference. -- Charles. {sun, amdahl, ucbvax, pyramid, uunet}!unisoft!cander
