HELP!!!!  I am using an Amiga 2090 controller with a SCSI drive manufactured
for the Mac.  When I format the drive everything appears normal.  The format
program runs to completion with no mention of errors.  If I run a program to
check for bad blocks at this point I get no indication of bad blocks.  (BTW,
this drive has automatic (i.e. transparent) handling of bad blocks.)  The
disk icon appears normally and I can read and write to the drive.  Then....
when I use the drive, I will eventually get a 'Read/Write Error' requestor
for this disk.  A disk sector editor will refuse to read the sector in
error.  In addition, if the 'bad block' checker is run once I have used the
drive for a while, it shows a large number of bad blocks.  Once those blocks
are removed by the 'bad block' remover, the disk often becomes 'Corrupted' and
the system will refuse to use that disk.
    It seems that there is something very significant happening here!  Are then
there major bugs in the SCSI portions of hddisk? What is happening?
