Hi. I was cloning my laptop hard drives today,and I did something I hope I can fix. My new hd was not recognized at its full capacity,so I booted up darin's boot and nuke and chose the quick option. However,I had smartly left my origional hd connected,so it began to wipe both. As soon as I saw it,I cancelled the operation,I'm not even sure it hit 1% done. However,I can't boot into the drives. I'm hoping that just the mbr was touched,and I was wondering how I can fix this. I know that there are ways to restore the mbr,but I'm afraid to do anything until I get some advice since I'm not sure if DBAN wipes drives in any other format. Thanks.

EDIT:I booted into Recovery Is Possible(RIP,and when I did fdisk-l it told me that no partition table was found. I am not sure how to fix this. I also forgot to mention before that I made a slackware boot disk if that helps.

Download WPARTNFIX. It is a DOS utility that reads your filing systems to rebuild the partition table.

If you have a copy of the partition table you can re-construct it yourself, using a Live CD program like cfdisk.

Better option for that would be testdisk - it's open source, and will find Linux filesystems as well as M$oft. And it's on Knoppix as well as most (all ??) other recovery type disks.
Should be able to recover partitions not hit by DBAN.

As for anything that was hit, no chance - the filesystem metadata is at the front of the partition. You may be able to get at, and recover, files using something like foremost (forensic software), but it'll take a lot of time.
