What rescue disk (rescue CD/DVD) would you recommend for an user which unfortunately needs to rescue data from a bad disk (filesystems does not mount when using LiveCD, though fdisk looks O.K.) for a very first time?
System does not boot from HDD: grub prints
error: attempt to read or write outside of disk 'hd0' grub rescue>
When trying to use e2fsck, or mount filesystem, or just list metadata with tune2fs I get:
$ sudo tune2fs -l /dev/sda6 tune2fs 1.42.5 (29-Jul-2012) tune2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda6 Couldn't find valid filesystem superblock.
Fortunately booting from LiveCD works (I am writing this from Lubuntu 12.10 LiveCD).
