Hi,
I'm sorry for this slightly OT question.
As in subject, I've a SONY DDS2 tape drive with 90m DDS tapes which
behaves in a very strange way. I've loaded a tape and issued:
> tar cvf /dev/nst0 /stuff
tar doesn't complains.
After, I rewind the tape, extract the archive and verified that data is
stored correctly.
Now comes the tricky part.
If I eject the tape, Voila', the tape is unreadable. I get
after loading the tape:
> mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN
> mt -f /dev/nst0 rewind (just to be sure)
> tar: /dev/nst0: Cannot read: Input/output error
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now
> mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=-1, partition=0.
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (1010000):

I get same I/O error if issue mt fsf 1 from a rewound tape. If I
overwrite the tape with a new tar i'm again able to read the content
but unless tha tape in not ejected.
Has anyon e seen this before? The same kernel/st handles properly an
SLR-100. Needless to say that i face the same problem running amcheck.
TIA for any suggestion(s),
