Thanks for the report.

Does DISKOPT crash immediately, when you start the optimization process
or only after long hours of work? Does it cause any data corruption in
the file system or is it a hanging "piecefully"?

I have a suspicion, that the problem might be caused by DISKOPT running
out of memory. So, does it work OK, if you select other sort options?
Does it work, if you run another disk optimizer first (say OPTIMIZR
in PC Tools), so that it has to accomplish an "easier" task (less
recursion)? How many directories/files do you have on the partition
in question? How much free memory do you have before you start DISKOPT?

Try EMM386 /VIDEO and then MEMMAX +V before you start DISKOPT?
This will give you 64..96 KB more conventional memory. Any change?

Well, AFAI see it, this should not matter. But still, what kind of
SCSI drivers do you have? Which versions?

Greetings,
