got an P3 win9x box here and getting extremely slow transfer rates when
copying between drive 0 and 1 and between different part. in drive 1.

explorer stalls and process must be killed, but usually just very slow,
but ONLY on some directories-some go fast and other go really slow, not
dependent on amount of data transferred.

bios is set for dma/level2, but dma is not enabled in os.

one drive died, i think from these frequent stalls and sudden process
kills.

what's wrong with the hardware???

Both drives on the same cable (master/slave)?
IDE cannot do a direct transfer on one controller/cable, only one device at
a time. You want your harddrives on separate cables (primary/secondary).

Run the diagnostic floppy (should be bootable) you can download from your
harddrive manuf. homepage.
Disable on-access-scanner(s) for a test.

Then backup your important data, and then enable it.
If it doesn't work, it probably will give a bluescreen. Under weird
circumstances (flakey controller, wrong driver) you might get massive
corruption.

Usually, drives tend to fail dma and become noticeably slow from multiple
retries, before they finally quit. Time to get a new one and do a image
backup of the old one.

Could as well be the cable - try a new 80wire cable, and make sure your
drives are jumpered correctly. Never leave a open tail but put the master
on the end of the cable.
