Greetings,

I've just purchased a Conner/Archive/Maynard 2.0GB DAT tape drive 
for my FreeBSD/Win95 system.  I installed it, checked the kernel
and /dev for the apropriate entries and did a "dump 0f /dev/rst0 /".
Then I did a "cd /tmp;restore -ivf /dev/rst0" and then "add *" from
within restore.  The dump worked.  After using QIC-80 drives it
was incredibly fast.  The restore got 34MB into the tape and then
the sh*t hit the fan.

First, It reported data error reading tape.  No problem, just let it
abort.  THEN I got bt0: not responding and attempting reset and then
invoking debugger.  THEN the kernel paniced.  I'm currently in the 
process of putting my root partition back together again. :(

Question, will a bad tape cause the tape drive to hang up which
would cause the SCSI card to hang, thus the system?

System:

FreeBSD 2.1R (walnut creek cd)
486DX4-100 (generic MB)
32MB ram
Buslogic BT545 ISA SCSI card
Conner 4320 2GB DAT
Toshiba 3401 CD
Quantum 500 MB SCSI2 HDD (/usr)

Thanks in advance

Mark
