Hello all. Sorry if there is a thread about this elsewhere but I'm having issues that are making me crazy since I am yet another one that didn't have a backup. It's a long story and I'm going to try to remember everything i did so sit down lol.

I have a 1TB LS-CH1.0TL-US, not sure if its v1 or v2 or the firmware. I got 3 power spikes/outages in a row. Although I was plugged into an APC surge protector which was plugged into an in wall surge protector I still got blasted.

When I went to access my NAS it could not be found by PC (Win7) and had the E06 error.

I then hooked the NAS enclosure via network cable directly into my PC and tried to EM start and load firmware. I've pretty much tried every idea on this site.

Next I purchased Windows UFS Explorer Standard V4. When running it on the drive it stopped at about 6.3% and after letting it sit for about 48 hours and it counting up to an estimated time of 250hrs+ and still wasn't moving past 6.3% I decided to stop it before it damaged the HDD any further.

When nothing I did worked I opened the NAS removed the HDD and hooked it up internally. I purchased 2 new HDDs, on one I installed Ubuntu 11.10 which said it had 1256 bad sectors and needed to be backed up cause failure was immanent. I ran gnu ddrescue to create an image which I saved 2nd new HDD I saved the image on an XFS partition.

I only made an image of the data partition which in Ubuntu is sdb6.

When I tried to mount and read the image I had issues. Possibly because I've never used Linux before and have no idea what I'm doing. Someone from the Ubuntu forum has been helping me with the code.

Today I took the HDD with the backup image of the data partition created with ddrescue and hooked it back up to my Win 7 machine. I ran UFS explorer on the image and it created a backup. When I go to read it all it shows is inode files which I can't open. I think I'm gooing to have to get a 3rd HDD to save the back up of the image on before it becomes a file tree again and I can read it.

Has anyone had a similar issue that cen set me straight with this? Any help is greatly appreciated.

Sounds confusing!?!?
Did you made an image (one file containing the raw disk content of your data partition)
or did you image the partition ("cloning" the data partition to a partition on a different
disk)?
Depending on this, the way to go further differs.
When you attached the original disk to a PC, did you ren smartctl to check if the disk
detected internal damages?

Yea its confusing alright. I rant SMART check and it told me failure was iminent, I then used ddrescue to image all 6 partitions from the NAS to a single 1TB partition created on a new HDD

So now what you have are 6 files with bitwise images of
each of the 6 partitions of the LS.
I am not aware of any rescue applications which can look
into bitwise image files for rescue.
Maybe there is a way to mount this kind of images?
If not, your only way will be to write each of the images
back to a spare partition/disk and then to rescue your files.
