Is there a way to know if the tar file test.tgz has files which had problems ?
I have already said it and i will repeat it here: THIS IS NOT A TAR-ERROR! It is an error reading the disk, tar just reports that error.

What you need to do includes: repair the filesystem (which might well be beyond repair), get another disk, recreate the correct contents of the file somehow (maybe database methods might help, like rolling back archive logs, etc.).

Look: you have a file and some part of that file is not readable, because it is damaged. Regardless of the tool you use to read it - cat, tar, cpio, whatever - all these tools will fail for the exact same reason: some part of the file is not readable. If you give a book to someone and he complains that page 245 is missing you are not going to "correct the persons reading" - you need to provide the missing page for the complaint to go away. For the same reason there is nothing you can do with tar or the file it produces, only with the reason for the error it reports.

I hope this helps.
