Worst case

[plustig]

Hi,

I was a running my NAS with two 500 MB WD Raid Hard Disks in a Raid 1 configuration. Two days ago my NAS stopped working. Red light was flashing and web interface was not accessible anymore, but the NAS was still pingable. I found out that the first hard disk was the problem. After removing the hard disk, the system was running again, but the problem is, that the data on the second hd was last updated on september 2007. Unfortunately my NAS didn´t report any problem.
Accessing the first hard disk to recover data, was not possible using Linux (Knopppix). I tried fsck and testdisk, but I got an error regarding fs and Superblock. I also tried the two in the forum recommended windows tools (linux read and recovery). The reader tool couldn´t read the disk. The other tool is working, but I had thousands of pictures on my harddisk and the recovery cannot create original folder structure or filenames. Has anyone another idea to get my data back?

Thanks,

Patrick

You say that you were using Raid 1 so the same data should be on both disks.

You say that you're trying to recover from disk 1 which is the failed disk.

Why?

Disk 2 should have the same data and if it's working then the data should be easily recoverable.

The disks are in a standard linux format and should have all of the original folder names and files intact under the /raid folder.

If it's not on disk 2 it wont be on disk 1.

You are right, but that is exactly the problem. My second hard disk hasn´t been refreshed by the raid controller since September 2007 and there has been no error reported by my NAS. This is really bad, because this is the standard functionality of a NAS with raid. I didn´t notice, because this was the second disk and you always see only the content of the first disk. This should make everybody here a little bit worried!
