Remember what I said about Desktop Environments?  Network Manager with
hal is part of a desktop environment.  Its fitzing with the drives.

Your kernel is seeing the drive, assigning it to /dev/sda (around
19:37).  A couple of minutes later (19:39:35) something causes the drive
to abort.

Perhaps someone can tell you how to get out the DTE while you
troubleshoot this.
