Recover partition after overwritten with dd

orschiro · 2010-05-30 20:10:27

Hello guys,

accidentally I've overwritten my external hard drive with the latest archlinux image. *damn*

The partition sdb1 on it was decrypted and mounted when I used dd-command to write directly on /dev/sdb.

Is there any chance to recover the files? My disk is 250GB big, so perhaps dd wrotes the ~160MB only to a part of the drive and the rest can be recovered?

Best regards

Sorry, but I think you're hosed. Hope you have a recent backup. From wikipedia: "It is jokingly said to stand for "disk destroyer", "data destroyer", or "delete data", since, being used for low-level operations on hard disks, a small mistake, such as reversing the if and of parameters, can possibly result in the loss of all or some data on a disk."

Searching the forum for "recover" returns a few results, including http://bbs.archlinux.org/viewtopic.php?id=97356 which seems to be at least somewhat interesting...

I think testdisk would be the way to go, but considering that your external partition was encrypted (with cryptsetup, right?) I think the data is unrecoverable...
