The 50 pin connector connects only the CDROM, which is properly terminated. The 68pin Ultra connector goes to the back of the machine where the DLT connects to it via a cable. It also, is properly terminated. The 2 disk drives are internal and are connected to the Ultra2 connector with the Adaptec Ultra2 cable (with terminator on the end). I've upgraded the firmware in the DLT to the latest available on the Quantum ftp site. Amanda backs up the remote machine and all partitions other than da1s1e to /d1/dumps and then dumps that to tape. This part of the backup works fine. The problem occurs when amanda is backing up da1s1e directly to tape, sometime during the dump it fails. I've seen anywhere from 3 to 7 GB dumped sucessfully before the failure. This same setup had been running without problems for months. Any ideas as to what is happening? I am running 3.1 Stable cvsupped on 4/17.
