A friend, who is not tech savvy had a hardware RAID of two disks. That means he had either RAID 0 or RAID 1.
All of a sudden, the RAID disk disappeared from his windows, wasn't listed in Computer Management and during boot the hardware RAID card was reporting any disks.
I have a SATA dock (USB) and i used it to test the drives. I tried in windows and mac but in both cases the drives wouldn't show up even as devices.
Is this check i did correct? if the drives are not listed during booting or in the OS as device i assume their controllers must be fried.
