Just unpacked my Drivestation Duo. Model # is DriveStation Duo™ USB 3.0 - HD-WLU3R1.
Running Mac OS X 10.7.3 on an intel macbook pro. Drivestation is in Raid 1 mode
Tried to format to Mac OS Extended several times, but after formatting was completed, drive would not mount. I was able to format the drive using the procedure described in this thread

Format was succesful, but after repowering the drivestation, I get a red error light on drive one (it was green before formatting). I don't understand why formatting to Mac OS Extended caused drive 1 to fail.
I pulled out the failed drive and reinserted it. I got the blinking red light (rebuilding) for about 12 hours. I came back to find all the status lights on the drivestation off. I repowered the drivestation and I still have a red failure alarm on drive 1.
It's hard to believe drive 1 failed due to formatting to Mac OS. Is there anything else I should try?
