Okay, I'm back again with new problems.  This hard drive isn't more than
two weeks old, and has been behaving very erratically.  I already explained
about the failure in which it wouldn't respond until I rewrote the partition
sector, and then one of the files was corrupted.  That was yesterday.  Today,
it again wouldn't boot.  Checking the directory, I found that all the entries
were there, but garbled.  I looked at it with disk doctor, and found that
about every other byte in the directory sector had been scrambled.  Also,
the directory sector had been moved from #91 to #99.  I tried to fix that,
and then the HD stopped responding at all.  I rewrote the partition sector
again, and it basically got fixed, except that I had to reinstall ICDBOOT.SYS,
and I had two directory sectors: the original one at #91, and the scrambled
one at #99.  This is the second time in two days that things got weird, and
this time I didn't even do anything that could be a likely cause.  One clue:
I get "sense 20" error messages all the time.  (Once it said "msense 20.")
I know that Bill White has gotten these as well, and found them to be 
harmless, but I wonder if they're related to the problem.  Any ideas, anyone?
I have a Seagate 250R, an Adaptec 4070, and the ICD host adaptor.  I use the
most recent version of the ICD software, and I have control.acc, starstrk.acc,
and trbocolr.acc installed, with settime.prg in the auto folder.  The 
applications I use include Flash, 1st Word+, Opus, TeX with dvidsk, zoo.ttp,
and lately, disk doctor.  Thanks for any help!
