External HDD not recognised

[n1m3s]

Hi folks,
i've got a problem. I had an external hdd connected to my tv, one day, my girlfriend touched something and after that the hdd became unaccessible from tv, from pc...
It's kinda weird because it seems that if has been formatted, but it hasn't any file system...
When I connect it to a pc, it is detected, but not accessible from my computer, but it appears on disk administration (as shown on attached picture). There are no useful options available on right click menu (just dynamic disc conversion).
I would like to recover the hdd to the previous status with all the data stored in it. Is it possible? What tools should I use?

Thanks a lot.
