I'd like us to consider officially renaming this either "irrelevant error
of the month" or possibly just "Trivial Error", because it happens to
often and is so trivial.  Error #5 is a scsi phase error, and the software
simply tries to read the block again (if I understand correctly, this is
basically when the drive isn't ready to send the data requested).  It's
not a fatal error, by any means.  Assuming that NetBSD doesn't crash
within the booter itself (which is rather unlikely, but still possible),
chances are, your Zip drive has a lower SCSI ID # than your NetBSD drive,
so since NetBSD identifies a drive by taking the first drive (ID 0) as 0,
the second drive (which could be ID 3 or ID 5 or whatever) as 1, etc. 
until it reaches ID 7 (the computer itself), basically your drive may
appear at a different device number. 

'Course if it's crashing in the booter, then something else weird is
happening, like a termination problem.  If the zip drive has
auto-termination, turn it off, and terminate manually.


Hope that helps,
