Your volume should still be accessible with 1 drive removed, something is definitely wrong. What does the BIOS show? Is the array degraded or is it invalid? I have two 2220 controllers and an array with 1 missing drive shows as degraded whereas it's invalid if multiple drives are missing.
For 2 months I have 8 of them in a RAID-5 array, only had to RMA one of them which didn't work from the start. I'm still running on SD17 revision since I have no problems with the drives and all my data is backed up.
Did you have the same hardware overclocked with a different OS before? I have a Server 08 x64 with Q6600 CPU and currently have it clocked at 3.0GHz, just changed FSB to 333MHz and upped Vcore slightly. I could run it higher but there's no need for it for this server.
Maybe some of your...
In his case it doesn't matter what raid level he used. If it had been RAID-1 he still wouldn't be able to recover his data because essentially his raid controller is dead.
Anyhow, to OP: You should be able to read your drives if you buy another mobo with identical raid controller. This...
With 14 drives in RAID-5 you have a high risk of subsequent failure while you're rebuilding a degraded array. I'd setup two RAID-5 arrays and span both physical volumes within Disk Management to a single logical volume.
I think once you install dd-wrt or comparable firmware on it most of the p2p problems go away. I'm using an early version WRT300N and it has been running without any problems since I installed dd-wrt. I've probably maxed out my 1Mbit upload bandwidth for 6 months straight.
