I had one external drive on which I was storing a large quantity of data; the drive is/was encrypted using gnome disk utility. I got a second drive for redundancy and I was preparing to encrypt it. Unfortunately, I overwrote the device book partition for the original external drive:
~$ sudo dd if=/dev/urandom of=/dev/sdb1 15585+0 records in 15584+0 records out 7979008 bytes (8.0 MB) copied, 1.30506 s, 6.1 MB/s
So that is a disaster. Curse my fat fingers. Is there anything I can do to restore access to the drive?
Some output from fdisk below. Device mounted as
sdb was the original drive, the device at sdc the new drive.
