Do you have MD5, SHA256 etc... checksums of the
.tar.gz files somewhere? Do they still match, or do
they differ now?

(If they match, you have a software problem with tar
or gzip; try reading the files under Linux (Knoppix?)
just to be sure. If they don't match, either the media
is corrupt (very likely), or something's wrong on the
code path that reads your backup device (a lot less
likely))
