I have a Western Digital My Book Studio Edition II 2TB external hard disk drive. Internally, it has two 1TB drives configured in a RAID setup. I recently purchased a Drobo and no longer want to use the former for my media storage needs, so I figured I would remove one of the 1TB drives inside it and plug it into my Drobo and use the Western Digital for the purpose of backup.
Removing one of the drives inside (I removed the one labeled ‘B’) was straightforward enough but when I plug it into my Mac, the LED indicator on its face is slowly flashing now (once per second) and it won’t show up in the Finder or in Disk Utility.
Can someone tell me if this is because I disturbed the RAID setup? If so, is there a way to reconfigure it so that it works with just the one 1TB hard drive in it?
I checked the user manual and it says that this sort of flashing of lights happens when there is an over-temperature condition and that I should try to reconnect it after a couple of hours. But since I wasn’t using this hard drive before I did the replacement, I don’t see how it could have heated up.
If anyone could offer some help here, I would really appreciate it.
