How to Repair a Raid 0 Disk Group?

i have 5 disk in software RAID 0 in XP SP2.
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 ?
data from the raid is now being recovered using 3rd party software that doesnt care about the errors on the initial record in the raid.
takes longer but everything is extracted.
sadly noone came up with a way to correct this error which apparently doesnt stop other software from accessing the data.

    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.
