Western Digital My Book Thunderbolt Duo will not mount.
My Thunderbolt drive Will not mount. Does not even appear in Disk Utility.
The power connects, and you can hear the drive functioning, however the light on the front no longer stays on and the drive does not connect to the computer at all.
When I took out the individual drives and connected them using an external usb device, each drive was fine.
They are RAID partitions, so I cannot recover the data without mounting them together.
So, I am thinking it is the thunderbolt ports. I tried both ports (there are two on the back, and tried a different cable. Nothing happens.
Is this a good question?
