Hmmmm, interesting. Then, I would say that the problem concentrates on
the controller or the drives, since you have other disks (I'm assuming
same make/model here), that has not failed. Do you have other machine
were you can check if the drive respond or if it went bad definitely? If
it is physically damaged, then I would say that the problem is almost
surely on the drive itself. If some (or most or all) of the errors can
be corrected using other controller/motherboard, then the fault is on
the electronics. 

Hope this helps,

Good luck,
