Corrupted file recovery

Hi all;
I have a divx reader with hard disk connected by a wireless network to my PC: while I was renaming some folders the network went down and the folders become files, so now are unreadable.
Now, when I connect the network drive, in the left column I have 8 folders (instead of the 10 that I had before) and two files of 0kb.
Before this problem these two files were two folders containing hundreds of files.
How can I restore them? remember that I don't have a physical access to the drive, only by network.
Thank you

Go to the HD.
Create a full image with "dd"
Try to find your way through the file system. And if you are familiar fix the problem.
Else you should get a forensic/recover guy.

There's plenty of forensic tools available, there's especially some really good ones for Linux. I remember using one awhile back and recovering tons of stuff.

There's even whole distros like Helix designed for this. I'm pretty sure Helix isn't free anymore though.

No, but you can always look for the last free version. 2008 R1 I think.
Assume that everything I say is or could be a lie.

File based recovery on NTFS/NT: http://www.piriform.com/recuva

HDD bad sector based recovery:
http://www.grc.com/sr/spinrite.htm (commercial and very damn good)
http://www.gnu.org/software/ddrescue/ddrescue.html (open source, but not as good as spinrite)

I'm actually a spinrite site license owner, and i run it on all systems at level 4 every couple of months just for preventive maintenance (PXE booting the ISO over LAN with gPXE + memdisk append iso raw initrd=SR.iso FTW!!)
