Hi Paul
This is a common problem with both DAT and 8mm tapes
A first step would be to look in your /dev/mt or /dev/rmt directory
and try to use a tape device a variable blocksize, so
tar xvf /dev/mt/tps0d2nsv
(the "2" is the SCSI ID of the tape drive)
Another possibility is that you need so swap your bytes on one drive
compared to the other. You can do this with
dd if=/dev/tape conv=swab | tar xvf -
Finally, sometimes specifying a hard block size may help:
dd if=/dev/tape bs=32k | tar xvf -
(try different sizes instead of 32k in combination with different devices
in your /dev/rmt directory)
hope this helps
