Swapping drives into new enclosure?

The controller on my old 2TB Gen4 G-Raid drive got fried recently (by plugging in the wrong adapter), leaving me with 2 inaccessable RAID0 disks. I managed to get an identical enclosure off eBay (GR4 2000) thinking that swapping in my old drives would work. However, on booting up the drive Windows will only see it as unallocated space.

Is there any way I can get the drives back up and running?
