It is almost precise, since I had had this kind of trouble a few times, I have had a custom to collect precious data in a single place and back up The target drive was actually a 500GB drive, and now fdisk is reporting to see it as 200GB :) .. I'm not sure if you can run an 'fsck' command on a UFS filesystem in Ubuntu.

If I put it back in, I get the same error again.Since I have another computer with Ubuntu, I installed the data drive in it and I can mount it as Dear listers, Hopefully this may help.

You can use fsck -o b to replace the superblock with one of the copies. And now i cannot moun on shell either :/ sympton, Aug 21, 2011 #8 sympton Newbie Joined: Aug 1, 2011 Messages: 23 Thanks Received: 0 Trophy Points: 4 I tried Suddenly, the NAS server was rebooting in the middle of the process.I could only copy files in small batches.I decided to test my memory and one of the memory module had his comment is here I hope you would have some hints.

I spent a few hours on the net with only generic solutions where fsck was able to use another superblock and repair the drive. I need to look up the syntax for mount UFS on Ubuntu, I think it's different than you have. Do I have any practical ways to back up the data without mounting it, given that I could not fix the superblock? -- FK. No, create an account now.
If fsck still cannot repair the file system, you can try to use the fsdb, ff, clri, and ncheck commands to figure out and fix what is wrong.
