I have a 6TB Thunderbolt Duo set to raid 1. I had a drive error in one of the drives yesterday. The drive started making odd sounds and a message popped up saying the drive was running in degraded mode. After a search online I concluded that the drive needed to be replaced. I removed the faulty drive to check the model number so I could find a replacement drive. I ordered a replacement hard drive and then I put the possibly faulty drive back in the thunderbolt duo and I turned the drive back on to use the drive. A rebuild began on the old hard drive. Is there a way to safely stop the rebuild so I can put in the replacement drive when it arrives? Another question, is it possible that the drive did not actually fail and the current rebuild will fix the problem?
Also, can I use the drive as I normally would during the rebuild? The drive was almost full, any idea how long the rebuild will take?
Thanks in advance for any help
