LT05 Unarchive Tape Error
LT05 Unarchive Tape Error
by Luke Allen on May 16, 2019 at 10:27:46 am

Howdy folks, long time reader, first time poster! Be gentle!!!

I have an LT05 tape that is causing me some issues and I was wondering if anyone here has any suggestions on how to fix?

I'm unarching a tape, which runs fine, untill it gets to a single file, which causes the tape to error and quit. The tape has around 1.3 TB of data, but crashes out after restoring just

Here is the last few lines of my logs

...

dd: reading `/dev/nst0': Input/output error

tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now

I also have a script I usually use for archiving and unarchiving and it says

usr/local/archive/tar: /dev/nst0: Cannot read: Input/output error
/usr/local/archive/tar: Too many errors, quitting
/usr/local/archive/tar: Error is not recoverable: exiting now
tar error 2

Is it possible to skip problematic files on LTO? Is there a way of recovering the rest of the tape? Any suggestions would be greatly appreciated.
