Read Error with tar xvf on a VDat

Read Error with tar xvf on a VDat

Post by Paul Rolla » Fri, 26 Feb 1993 18:41:42



Hello,

I've backed up some files using tar cvf on a VDat. Now, i want to retrieve
these files using tar xvf, but i have a Read Error. However, i *really*
need
to retrieve all the files that are not corrupt. Is there a way to get
them despite this Read Error, i.e how to explain to tar not to stop on the
first error it encounters on my VDat ?

Please reply as quickly as possible, it *is* important for me !

You may be able to read the tape with "dd conv=noerror if=/dev/<tape> |
tar -xvf - " (your milage may vary - the key is "dd conv=noerror").

1. Read Error with tar xvf on a VDat

This may be very easy to fix (if you're lucky).

Set the blocksize for the tape drive to 0. That might be enough.
