- Hi there,
-
- Can someone help me fix the following problem? Thanks for your hints.
-
- I want to backup files on a DAT tape connected to a PI,
- both tar and bru did not work.
-
- %tar cvvvvf /dev/dat .
- ...
- tar: tape write error: I/O error
-
-
- %bru -cvvvf /dev/dat .
- ...
- bru: warning - Input/Output Error
- bru: load volume 1 and enter device [default: /dev/dat] >>
-
- and on the console I got (in both cases):
-
- NOTICE: SCSI tape #4 Unrecoverable error
- NOTICE: SCSI tape #4 Unrecoverable error
-
- But I can still read a DAT tape with files on it both by tar and bru.
- What's the problem?
