I have a Mybook studio II (1TB : 500GB x2 ) drive that i had been using on my Macbook Pro with Firewire 800 .
The drive worked awesomely well up until two weeks ago ; now when i connect it to my MBP it is not detected or mounted , System Profiler indicates there is an Unknown Device. Nothing in Disk Utility .
Ive tried plugging it into my secondary laptop (Windows 7 ) using mini USB but it still wont get recognized .
The 2 - 500GB drives seem fine , they spin up with no weird sounds or issues , even the light bar illuminates and does its little jig .
From my diagnosis i think the RAID controller is busted , does WD replace these ? cuz my device is still under warranty , i have punched in the serial number and confirmed that .
