Basically I just setup a RAID1 configuration with two 1.5TB WD drives in an external enclosure connected via eSATA to my main PC. Once they synched everything appeared to be fine and I was able to access the disk and was feeling quite proud of myself. I ran into a secondary issue however where the external enclosure kept powering off and then not waking up when the PC came out of hibernation so I've been playing with some of the power management settings trying to resolve this (specifically I set the 'Turn Off Hard Disk' option to 'Never' and the 'Link State Power Management' under PCIExpress to Off (my eSATA connection is a card on the PC)). So far this didn't fix the problem but that's another matter entirely, onto the immediate issue:
Today I was messing with some cabling behind the PC and I inadvertently knocked out the AC power plug and turned the machine off. When I rebooted my mirrored RAID array did not come up so I went into Disk Management to investigate. It showed my mirrored drives as 2 seperate entries in a 'Failed' state. It also showed a 3rd drive that it listed as 'foreign'. So after a little googling I tried reactivating the failed mirrored drive. First I gotta popup that said 'The Plex is missing' and then both drives updated with the status 'Failed Redundancy'. Some more googling and I followed this article: http://buildegg.com/bewp/?p=44 and removed the failed mirror. The drive then converted back to a simple volume that was accessible as normal with the files intact and the mirrored volume of course was removed. Next I clicked on the 'foreign' disk and selected 'Import Foreign Disk' and lo and behold it restored the 2nd disk. So now I have 2 simple volumes with the same data but no RAID1.
Anyone have any clue what the hell is going on here and how I resolve this?
thanks so much for your help
