G'day,

I've just lost a partition on my sda disk (sda7) which fails to boot (it has a number of Frugal Pups) or to mount from Pup on another partition.

I've got ddrescue to copy the faulty sda7 to another drive. It reports a 119kB error before starting to copy what it can from sda7.

On this copy, fsck reports a super-block error/corruption, as it does if I try directly accessing the original sda7 with fsck.

Is this the right way to use ddrescue (is there some other program to try to explore the rescued data or the original ext partition)?

And is a super-block error fixable? Or do I just wipe and reformat the partition with GParted and re-install the Frugals and their sfs files

Thanks for any advice,
David S.

David,

I've googled a little about the superblock error and it seems to me, that it's fixable without dataloss.

I'll see if i could find a good advice about a stategy snd will report back.

some more infos i've found (and on disclaimer )

from ddrescue online-manual

If you are trying to rescue a whole partition, first repair the copy with e2fsck or some other tool appropiate for the type of partition you are trying to rescue, then mount the repaired copy somewhere and try to recover the files in it.
