In desparation, i used ddrescue (successfully!) to save a failed hard
drive. Unfortunately, i didn't read the instructions carefully enough.
The failing HD is 40 GB (/dev/sdc)
I decided to put the rescued data on 500 GB misc. drive (/dev/sdb)
stupidly, i typed:
ddrescue -n /dev/sdc1 /dev/sdb1
Instead of creating an image, like i intended, I just overwrote the
entire partition on sdb1! I got the rescued data off that i needed, now
i need to
get /dev/sdb1 back because now all the system sees is a 40GB partition.
Any ideas?
thanks

Unless I'm completely missing something, you will never be able to fully get back your data on /dev/sdb1, since you over wrote it with the contents of /dev/sdc

Was there anything useful on that partition before your "Oops"?
Because the filesystem that was once there is not recoverable. However, you may be able to use file-carving to recover some files from what you currently have. You only overwrote 40 gigs out of a possible 500 gigs.
Look into Photorec or Foremost to recover your data.
If the problem is that you just want to be able to "see" the other 460 Gigs that was once there, reformat the partition. You currently have a 500 gig partition with a 40 gig filesystem on it. That's why it only appears as a 40 gig drive.
Good luck!
Andrew

Hi Michael,
You're not completely clear on whether you're trying to recover the
*data* that was on /dev/sdb, or just get back a blank 500GB partition.
The latter is easy, just format a blank filesystem, e.g. using "mke2fs
-j /dev/sdb1". (I assume you didn't overwrite the partition table since
the command-line you quoted would not do so.)
The former is more difficult, and as already has been noted, you
probably won't recover 100% of what was there.
I would use a tool such as photorec to retrieve the files. Photorec is
my preferred tool, but you could also try scalpel and perhaps some others.
Good luck,
David
