Not to insult your intelligence, but have you tried:
1 - mt -f /dev/rmt0 rewind
2 - Can you read the tape in the old drive or any other drive?
3 - Have you used a cleaning tape?
4 - Have you tried to create a new tape in the DDS-4?
These may seem painfully obvious but they would be the first
I would try

we just purchase a IBM Pseries computer. This new computer has AIX 4.3.3
and DDS-4 tape driver installed. I am doing the migration work from old
server to Pseries. The old server has AIX 4.3.3 and DDS-3 tape driver
installed. I "tar file" used DDS-3 cartridge (125) and bring this tape
cartridge to DDS-4 tape driver. when I type "tar tvf /dev/rmt0" following
message come out:
tar: 0511-193 an error occurred while read from the media
the media surface is damaged
The DDS-4 flash light will be ON and "errpt -a" show "tape dirty head". I
have been replace several tape cartridges (brand new) and still the
same. the tape setup parameter are:
DDS-3 DDS-4
-------------- -----------
Block size 1024 1024
density #1 37 38
density #2 36 37
data compression yes yes
I have been tried following setup still make NO difference:
1. change DDS-4 "density #1" to 37 and "density #2" to 36.
2. set "block size " to 0 on both DDS tape. In this case NO message come
out and you can see DDS-4 tape driver continue read tape cartridge, but
nothing show up.
Can anyone help me on this?
Thanks.
