I now tried something different. I issued a

Okay, this is not getting results. I believe that a long way back
in the thread that you said that only one drive make+model exhibited
this issue--other drives worked fine.
Right now, I can't find the post where you specified the drive. Who
knows--I might have one.
Western Digital Caviar 31600 it is.
I'm waiting for a 32Port-LA (might take up to a month). When it is there
I'll continue debugging that issue and see what a MS-DOS does different
from what I do.
