Prime has a few surplus Maxstor 3280 SCSI disks (about 240MB) that were
ordered with a non-standard block size and non-standard microcode.  I
want to restore one of these disks to the default state where the block
size is 512 and the standard microcode is used, at which point I'll plop
it in a case and use it as an external drive on my Mac.  There are a set
of SCSI commands that can be used to read and write the disk parameters. 
I've been told there is a command sequence that will restore the
original microcode behavior.  The problem I've got is how to formulate
and send these rather specialized SCSI commands. 

I checked the SUMEX archives, but none of the SCSI-related programs
there seemed applicable.  Before I try to write a one-shot program to do
this, I wanted to solict feedback from the net as to what tools are
available to assist in this effort.  Are there any inexpensive programs
in other archives that would be useful? In particular, the SCSI Tool
from Arborworks listed for $175 on page C-44 of Fall 1989 APDA catalog
looks like it would let me do what I want.  Has anyone used SCSI Tool
(not to be confused with Paul Mercer's CDEV with a similar name)?

Please reply by mail - I'll post a summary.

Thanks in advance for your help.
