I started poking around online for how that works, and I found repeatable case of what I hope is the same error (one tar from the bad scsi disk piping into another tar onto a good scsi disk). One problem I ran into is that scsi_logging=X as a kernel parameter doesn't seem to work in 2.6.0-test1, so I put in a S00 init script to do the: echo "scsi log all" > /proc/scsi/scsi The resulting /var/log/messages is ~18M, compressed down to 300k. http://acm.cs.nyu.edu/~tugrul/scsi/messages.bz2 Is this what you need? I did a quick test of the above case on a 2.4.21 kernel and it didn't seem to trigger anything evil. If it turns out to be a firmware problem, is the firmware upgradeable or do I have to buy a new drive, in which case is there a blacklist? Tugrul Galatali
