Thanks for the suggestion, Walter. I did make a copy of the tar.gz file but I got nothing useful out of it. I am still waiting now for the darn activation code for a MS-based ext3-aware data recovery tool... Maybe that will finally crack my rough luck thus far - if it ever arrives!

Tom, thanks for the note about gunzip -c being the same as zcat. I will make another backup and give that a go, though my hopes are narrow... Oh, and given the current state of my hardware; I certainly would not trust my tape to make another dump so Walter's suggestion is/was valid.

Madison (who has passed the 24hours mark and wishes she could just get a break and then go home!!)

For your daily backup operations, a recommend you to use star instead of tar. star has a nice "diff" option, which allows to verify backups. Like tar, it's multiplatform, so you can take your tapes to a friend with the same tape drive and try to restore data on his system to make sure that your backups make sence.

Don't use zcat to decompress a file ... use the appropriate tool, gunzip:

gunzip file.tar.gz ls file.tar

NB. gunzip -c file.tar.gz is identical to zcat/

He already has a backup of the tar.gz ... it's called a tape

PS - I got a dd of th last tape that ran (finally) and it is about 3.6GB (about right). I extracted it as a tar.gz (which should work) but it

claiming to not be a gzip archive... Any ideas on that front by chance?

*MAKE A BACKUP COPY OF THE TAR.GZ FILE FIRST* !!!

Straight from the man page...

tar -xvvzf foo.tar.gz extract gzipped foo.tar.gz

..did you remember the "z" parameter ?

I've had similar problems with tar.bz2 archives. I find that doing it one step at a time works. Note, you will need a *LOT* more diskspace.

Step 1) zcat filename.tar.gz > filename.tar The "zcat" executable is named "gzcat" in some versions. Use whichever one works on your system.

Step 2) tar -xvf filename.tar
