extracting files from old DAT tape
On a sarge machine, I have a WangDAT 3100 tape drive from the late
1990s. The tape from which I would like to recover certain files was
made back in 1998 with bru.
I loaded the module for it:
# insmod st
$ lsmod | grep st
st 29112 0 (unused)
scsi_mod 95108 4 (autoclean) [st ide-scsi sd_mod aic7xxx]
$ cat /proc/scsi/scsi
Host: scsi0 Channel: 00 Id: 02 Lun: 00
Vender: WangDAT Model: Model 3100 Rev: 02.2
Type: Sequential Access ANSI SCSI revision: 02
I insert a tape, the LED blinks many times and then remains on.
# mt -f /dev/st0 status
drive type = Generic SCSI-2 tape
drive status = 318767616
sense key error = 0
file number = -1
block number = -1
Tape block size 512 byte. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status = 0
General status bits on (1010000); ONLINE IM_REP_EN
Now (in my ignorance) I tried:
# tar xvf /dev/st0 *.xyz
tar: /dev/st0: Cannot read: Input/output error
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now
When I tried the tvf options for tar, I get the same result.
Can I extract individual files this way from a tape made in the first
place with bru?
