Hard Disc disappeared!

[BrianFWombat]

Playback was not working well so I restarted the box (via the menu) and on restart the Filelist is now empty.
When I navigate to /media/hdd/movie this is also empty.
I notice from dmesg that...

sd 0:0:0:0: [sda] Unhandled sense code

So it looks like my hard disc can't be read. But it does seem to be accessible...

Is there any way this could be recoverable? (Sorry I have no knowledge of Linux disc utilities)

have you looked in the mount manager to see whats in there ?.

blue button> ViX> mount manager.

also you dont by any chance have TSpanel installed ??.

[BrianFWombat]

blue button> ViX> mount manager... Disk on list.... Mount -> "Mount Failed"

system->hard Disk->Check Disk... "Error: Could this be a zero length partition? fsck.ext3 Attempt to read block resulted in short read"

[BrianFWombat]

TSpanel installed ??.
Not that I know of! What is TSpanel?

The disc is still there... just inaccessible...
