Disk Failure Light After Mac Extended Format
« on: March 19, 2012, 09:47:39 pm »

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?

Does formatting to a different file system actually make a difference?  Most likely it was just that the formatting process revealed a problem in the disk.
