dd: reading `/dev/st0': Input/output error
Hi,
I face some reading error while running the DD command to copy file from the IBM LTO4 drive. Does anyone face the same error before? What can I do with this?
mt -f /dev/st0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x44 (no translation).
Soft error count since last status=0
General status bits on (45010000):

Have you tried without the ibs=n option? Sometimes, letting the device figure out how fast to serialize the i/o works when telling it what to do does not.
Sometimes, real fast is almost as good as real time.
