MAC My Book Duo stuck on Mirror set rebuild in Progress. Help!

MAC My Book Duo stuck on “Mirror set rebuild in Progress”. Help. In this status for over 24 hours. Would like to unplug laptop. Do not want to loose data. Set for RAID 1 (Mirrored)


This status is normal, it’s best to let the rebuild process running for 48 hours, just make sure the hard drive LEDs are blinking.
