is it possible to get information from one bad split tar?
 

I made a split tar of my home, cause of file size issues. It seems that at some point, there's a problem with them when i "recat" them together and pipe them to tar:

cat *.tgz* | tar zxvf

At some point, it complains about a crc and quits.

So... I want to get the maximun out of those files so I lose as little information as possible.

How can I extract files from them?

tar has a built-in function for split tars to put them back together again. Woot, memory worked for me, it's the -M. Give man tar a try first.
