Hello,

first off, you should ask in freebsd-questions or freebsd-scsi
second this is a typical scsi problem. To solve:
- check cables
- check termination
and if the problem still exists, check again.
I speak from my own expierence, since I had this kind of problems one
year, cos I didn't see that there were two jumpers on the disc to set the
termination :-(
Greetings Andreas
