fs = XFS

problem is: the drive is not mountable (given previously stated errors) even 
in a live or rescue configuration.

now, I am running a test of this given that a friend of mine has this 
identical problem, only he has FORENSIC DATA stored on there and he 
ABSOLUTELY NEEDS TO RECOVER IT and thus, he is unwilling to try these tests 
on his disks due to lack of hardware backups (more disks).

this means, I need some way of recovering the data from the first of 2 discs 
given that the second one in the raid 0 configuration is either failed 
(hardware) or otherwise not usable.
