[ILUG] disk recovery [solved]

[Ian Spillane]

And the lesson to us all (apart from the essential immediate dd command):
BACKUP, BACKUP, BACKUP.

Thanks for updating on the story - nice to know it all worked for you.

The "file" command will help with sorting out the scraps.

> 2. backed up the drive - "dd -if=/dev/sdb -of=/mnt/tb1/200gb.bak.img" (took
> two days...)
> 3. ran testdisk to get some basic data about the drive
> 4. manually ran e2fsck on the drive, using a piece of lego and a pterry

> finally, had to upgrade the kernel to 2.6.29 so I could load ext4 without

> next step is to get a new drive and copy the files off the damaged drive.
