Get around a Device I/O Error on Restore

Created: 14 Mar 2005 • Updated: 21 May 2010 | 3 comments

I have a tape that backed up successfully and verified sucessfully and 2 days later when I try to restore a file from it, it gets a device I/O error 11 minutes into the restore and/or catalog process. I suspect it is due to a bad spot on the media. Is there any way to get around this and restore 1 file in an undamaged area of the media even though some portion of the tape may be bad?

You probably want to try re-cataloging the tape . You can try searching through the catalogs for that particular file while running the restore job (restore job->selection->search catalogs->file name) and then try restoring it. If that fails then I’m afraid the physical location of that file is probably damaged.

Hope this helps you out.

I tried all of those options prior to posting a message. The tape will not catalog (starts but has an error) and when I select any file for restore, it stops at the same point approx 11 minutes in to the process and reports a device I/O Error. I think there is a corrupt spot on the tape, but obviously it can't affect all of the files that are stored on there.

We have since restored from a month earlier tape that they had and rekeyed all of the information. I would, however, like to know if there is anything else that could be done besides data recovery for future reference
