I'm working with a machine that uses Asus A8N-SLI Premium motherboard, which has a Silicon Image 3114R RAID controller onboard and two drives in RAID-0 (why??!?!?).
The motherboard failed and I was wondering if tracking down a PCI RAID adapter with a 3114R controller to recover the array might work?
Update: I ended up moving the drives to a second computer and using Raid Reconstructor to move the data to a new hard drive but the advice below is sound.
