Last night I rebuilt my raid 5 array after one of the disks claimed "error" I took the following steps
Replaced offending disk with a similar one
Using the MediaShield utility in the BIOS (NVIDIA chipset mobo, hw configured RAID) I rebuilt the array.
Right here things get a little iffy. When I installed the new disk and went into my raid utility it showed two array, each with one of the disks from the 3-disk raid-5 array that had failed. Each had the option to rebuild by pressing 'r' but pressing 'r' would kick me back to the previous screen with no confirmation.
I deleted one of the arrays and kept the array that held my first disk in the series, then I hit rebuild and selected both my other disks (in order). In the operating system I can confirm that the MediaShield utility (software on OS not BIOS now) reports that my drive is rebuilding. I left it to run overnight and when I came in this morning it claimed it successfully rebuilt the array.
I try and open the drive which is now displayed in explorer, won't open. I open up the Disk Management snap-in and notice that 1) it is a 2-partition basic disk 2) one partition reports "unallocated" (one of the 1TB hdd's), the other partition reports RAW (another of the 1TB hdd's).
I have no doubt I can format them and have a functional array, but then my data would be kaput. Is there any way I can still recover my data? Where did I go wrong that I have this current setup?
