Hi All,
I need help to restore a tar backup from a tape that have some
broken blocks :-(((!!!! The box is a Linux 2.0.35 with AHA2940UW
and the tape is a TANDBERG model TDC 4100 Rev: =07. The cartrige
have 1,2Gb of capacity (950 ft. = 289,56mt). I've tried with some
variant of:
tar --ignore-zeros --ignore-failed-read -xvf /dev/st0
or
dd if=/dev/st0 of=tapedump conv=noerrors count=2000000
dd if=/dev/st0 of=tapedump skip=1056024 conv=noerrors count=2000000
^---- Start of broken blocks
reported by other dd's
but without lock. The tape report:
st0: Error with sense data: Current error st09:00: sense
key Medium Error
Additional sense indicates Read retries exhausted
and so on. I hope that some one reply me how to rescue this very
important data.
Thanks,
Roberto.
