- This could be cabling or termination.
- It could be that the drive is dying.
- It could be a driver bug.

Does FreeBSD 3.0 still install okay?  Perhaps it would be better to install
3.0 and update via cvsup/make buildworld/make installworld to the latest
-stable.  There have been some Adaptec driver fixes since 3.1 went out.

If you'd rather go with a release/snapshot, you could try the latest
3.1-STABLE snapshot from here:
