I got 2 Trancend 1TB hard drives in there

I got a powered USB hub to power the 2 hard drives, and I think the faliure happened when when this hub died

when this happened I could no longer see the share in the web portal but after some googeling I ran a command that i cant remember or find (please let me know if its important) now I can see the share, but as i said im missing some files and folders.

there is some important info on there, so any help would be great

hmm not much feedback.

well let me add a bit more info that might be usefull.

i have tried mounting both disks in ext2 volume manager with no luck both drives listed as raw, and neither ubunto and mint will not mount the disks.

can I "rebuild" the array/raid1 in ovm without loosing data?
i really hope for some feedback here, there is alot of pictures on there that...
