File System Recovery
Posted: Sun Apr 15, 2012 11:13 am
Hi all,
I have a OWC Mercury Elite Pro Qx2 RAID enclosure which uses the Oxford 936SE chipset. It has 4x Western Digital Caviar Black drives (2TB) in RAID5. Everything has been fine with this for a year or more. There was 1 large NTFS volume.
The other day, during it's normally scheduled Scandisk, it took forever and proceeded to do what looked like recover almost every file from something. After that, everything seemed fine. A couple days later, I noticed the drive wasn't appearing in Windows. I power cycled the drive and checked Device Manager, and sure enough it was connected. I checked Disk Management, and apparently the partition was lost. CRAP!
In R-STUDIO, it says the drive has a "Microsoft Reserved Partition" from 17kb-128MB, and then "Volume {some long id}" from 129MB-5.46TB.
So I ran an R-STUDIO scan. It found two blocks of recognized data, but neither has all of the data. Am I screwed?
I don't think this is a case of needing to do a RAID recovery since the unit mounts properly, unless that could help?
I have no idea what happened to the data. My only guess is that when I power cycled the enclosure, it didn't see a valid RAID set so it wiped and created a new one?
Ideas would be great!
