[aklug] Re: UNDELETE

Might get away with swapping the boards, I read that the majority of drive
failures of late are firmware and logic and not mechanical. I have not
personally done it, but I have seen it done.

One disk is failed. It will not read. I'd have to move the platters to a
working chassis.

Chances are that if I can somehow magically move the platters without
causing massive damage to the data that the logic board (containing sector
reallocation information) for it will also work. There's a darn good
chance the motor or heads are just wonky.

So here's the deal. I need to dump the contents of one to a disk image..
then somehow magically move the platters over. Anybody know how feasible
this is? I'd also like to get data recovered from this funky situation.

Yes,

Trinity Rescue Kit has a couple of utilities that you can use to recover
deleted files and partitions.

It scans the drive looking for orphaned inodes.

I haven't used a disk in a few years, but I have successfully recovered
deleted partitions and files from ext2 and ext3.

The newer version of Trinity might help.

Shane, perhaps you could image both disks and then trim one to synch up
with the other? Block sizes and sectors tend to be predictable. Assuming
of course that the manufacturer didn't add any curve balls to the
equation. Was dealing with mfg curve balls with a codec somebody on the
AMIA-L list asked about this weekend. See
