Is disaster recovery possible? List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: dm-crypt@saout.de Evening all, I'm not very hopeful of a positive response, but having just made my worst mistake in thirty years of computing I thought this would be where most of the relevant knowledge is. I have an external 1.5TB Seagate drive, encrypted with dm-crypt/luks and formatted xfs. In a state of dog-tiredness, thinking I was pointing at a USB stick, I have inadvertently wiped a few hundred MB of the beginning of this disk with: dd if=./archlinux-2010.05-netinstall-i686.iso of=/dev/sdc My question, as you might guess - is there any possibility of recovering the vast amount of data still on the drive? I could do it with an unencrypted disk, but I have no idea how to proceed in this case. Thanks for any suggestions. (I've managed not to cry so far...)
