data recovery -- please help!
Hi folks, I have a 60GB IDE ext3fs drive in a linux box that was running SuSE 8.0 and then pulled the drive out of the machine and tried to boot it from another machine. Thats when my trouble started. The drive booted all the way up, but then (maybe due to bad memory in the new system) the system became totally unresponsive. I had no choice but to do a cold reboot and from then on the problem got worse. So to make a long story short I now have a drive that I know has data on it, but according to fdisk has no partitions. So I guess this means that my superblock is hosed. I know that there is still valid data on the drive because I did this: 1. dd bs=8192 if=/dev/hdc of=/usr/local/hdc 2. strings /usr/local/hdc | more and I saw tons of stuff looks all so familar, but I can't get to it. none of the e2fsprogs such as dumpe2fs or debugfs work because they can't read the superblock. I tried using LDE, but none of the Directory views worked, however I could get a Block view of the data, but I don't know if that is of any help. So, if anyone knows of any way I can recover this data that is on this drive, but in accessible because most utilities rely on the superblock, which seems to be corrupted, I would reeeeally appreciate it.

If fdisk reports there are no partitions there then the partition table is corrupted. The table is on the first disk sector (If you don't use LVM - I'm not familiar with LVM.) I doubt any ext2fs tools can work when the OS doesn't know where the partition starts. You need to repair the partition table first. In the past, Unix system administrators often kept partition table data on a piece of paper. I don't think ordinary users do it. -- Alexandr.Malusek@imv.liu.se
