How to repair a raid 0 disk group?
Question:
recently all disks in the raid show up in disk management as "dynamic offline".
if i try to "reactivate disk" i get:
1-"Disk group TowerDg0: Errors in some configuration copies:
Disk Harddisk5, copy 1: Block 1: A format error was found in the configuration copy
Disk Harddisk6, copy 1: Block 1: A format error was found in the configuration copy
Disk Harddisk7, copy 1: Block 1: A format error was found in the configuration copy
Disk Harddisk8, copy 1: Block 1: A format error was found in the configuration copy
Disk Harddisk9, copy 1: Block 1: A format error was found in the configuration copy"
2-"INTERNAL Error - The disk group contains no valid configuration copies (C10000B6)."
i have gone so far as to test all disks for hardware errors and there are none.
i have tried "Active@ Partition Recovery for Windows" and everything i had in the raid shows up.
how can i repair the raid ?
Answer:
You've got to completely ersae them somehow and start over..
Here is the problem with a raid 0. If you have one drive partition error, you may loose all your data. I dont know any wat to recover data from a failed stripe other than what you have tried. There maybe software out ther to do this.
This is not a raid 5, and far from 5+p. I hope you have a good backup.
If you just want speed, run a stripe (raid0) but if it is mission critical you need to run raid 5 at least, then one drive fails, swap it out, rebuild and your done.
Raid 5+p (parity) allows you to continue working and hot swap any drive that fails.

Again, there is a reason you dont use raid0 for mission critical apps. Even if you can recover the data.
