[Hand shoots up, waves widely in the air...]

Yes, I too have trashed my root partition in an attempt to use dump to
a borrowed Maynard 525MB SCSI drive.  Got a number of wd: extra interrupt
messages and a bad disk label message.  Had to restore from a multifloppy 
tar that was, ahem, 2 months old.

On a backup related note, I now have an Archive DAT drive working with Pace's
SCSI driver.  The drive will work fine in SCSI-1 mode.  I had to make
some changes to get it to work in SCSI-2 mode.  I'm not planning on
posting the diffs since I'd like to sync up the 0.1 release when it
comes out.  The problem relates to the drive rejecting mode selects
when it has gone into unit attention following power-on.
