I'm assuming it's a v1, the only reason for this is that next to the serial number it is labelled as LS-CH1.

As for partitions, I have the following:

977 MB Ext2

4.77 GB RAW

977 MB RAW

917.20 GB RAW

There is also 7.64 GB Unallocated

So from that, it's obvious which is the data partition, but what are the others? I'm guessing the 977 MB ext2 partition (1st on the disk) contains the NAS os, but what's the 4.77 GB partition?

Nothing has been written to the drive, I'm fairly confident of that.

Lol the bomb making plans & monkey porn comment by the way!! I hope I didn't offend you in anyway regarding the mention of not wanting to send the disk off to someone I don't know, I hope you understand my reasons and also that I do really appreciate the time you've taken so far to give me some decent advice.

It would probably need to be NTFS or any OS X file system by the way, I think I have some files on there which are over 4 GB.

Are you in the UK and would you be confident of restoring all the correct file names and extentions?

Cheers,
Jay


It seems to be a CHLv2 of size 1 TB (that's the reason for LS-CH1, where the "1" stands for 1 TB).
Where are these displayed values for the partition size come from?
Was it your Linux system where you connected the disc to? If yes, I would assume it couldn't handle
XFS.
Only the first partition of a stock Linkstation is formatted ext2/3. All the other partitions, as long as
they are not a swap partition, are formatted with XFS.
XFS has some known issues on ARM CPUs on rare occasions. That's the reason why we (the community)
are wondering why Buffalo still uses this filesystem. They "implemented" a workaround by calling
a filesystem repair call on each startup.
But back to your problem.
If your Linux was not able to "speak" XFS, it would be no wonder why you couldn't get any data off
your disc. Use a recent Linux-Live-CD and see if it can detect the filesystems properly.
There is a Windows shareware called "Raise Data Recovery" which was used by a collegue of mine to
recover accidently deleted files on a XFS filesystem. This is not the exact same situation, but the company
claims they can also recover "lost" XFS filesystems. Maybe it is worth a try? At least you can see without
any payment if your data is still available (the shareware is restricted to allow copies of files of less than
64k only).
Best of luck.

The values I've listed above were from Windows 7, the only recovery program I have is called R Studio (http://www.r-studio.com/) and the version I have is Windows only. It's a little out of date, I did download and try the latest version last night and it found a lot more - although still no file names. This is the part that bugs me the most, the data looks intact except for the file names. Anyone know why this is?

I'm currently downloading the latest version of Ubuntu (9.10) and will give that a go.

I'll also check out the software you've suggested.

Many thanks!

Try the software first. It is dedicated to data recovery.

A quick update, the latest version of Ubuntu can see the data partition, but it's empty with just a spool and a share directory in root. 917gb free space.

I did and it's empty. I've let the Raise Data Recovery product run overnight and it does seem to have found a lot of info including all the original file names, I've yet to actually recover anything with it as i've not yet bought it - but it's looking promising.

A quick update, looks like the Raise Data Recovery is doing a great job! I'm 100 GB into the recovery and everything that's been recovered so far looks to be fine and everything has it's original file name.

All good so far, thanks for all the suggestions guys - I'll update once it's complete but it could take a few days to recover completely.

Almost done, well over 700 GB so far. Had a bit of an issue yesterday when the external drive I was using had some kind of panic – couldn’t continue writing data so failed. I kicked it off on my desktop PC with both hard drives connected by SATA and it’s been going since this morning and is nearly done.

As you’ve spent the most time and effort helping me out and giving advice, is the Buffallo NAS of any use to you? It won’t have a disk, but I’m happy to mail you the box and power supply if you can make use of it?

I realize this is an old post, but wanted to give my thanks - I had a similar issue with a Linkstation Live drive, had it attached to a box and tried to access via Knoppix. Couldn't find any files. Raise Data Recovery worked great. My only advice to future troubleshooters would be that Raise didn't like the USB drive I had connected to copy to. Finally tried copying to the PC sata drive and worked fine. Might have been my file structure ignorance.

Cheers

Hi

I seem to be having the same problem.

My data is there but when I try to extract data from it, it cannot find what file system it is. It cannot tell if it is XFS, NTFS etc.

How do I retireve my data with original file names and folder structure?
