Wow - I away from home for a week and came home to find my router in a weird state. No shares were available and Internet was down. I tried to log in to the router but telnet was not available, the admin password was back to the default, and only a few of the web pages worked. I rebooted the router and now it is the same state as yours. Obviously it is HDD related, and although it is still under warranty, I pulled the HDD out anyway to try and recover all the photos (and other stuff) I have on the drive (it was completely full when I left - I hope that didn't cause the problem).
I put the drive in a USB enclosure and connected it to my PC so I could try and mount it using openSUSE under vmware. No partitions are recognized and I can't force it to mount as it seems the partition table is missing.
I am going to spend some time trying to recover as much data as possible, but I was wondering if anyone has ever successfully recovered the drive after this has happened?
Thanks,
Hacksaw.
