RAID0 problem array broken

[Karsten Fuhrmann]

Hello,
tonight my RAID0 configuration broke.
It seems to be only a loose cable or power cord, which i fixed already.

But now my ar0 stripe will not be recognised anymore.
/var/log/messages showed this :
Dec 17 03:24:44 darkstar kernel: ad6: FAILURE - ATA_IDENTIFY timed out
Dec 17 03:24:49 darkstar kernel: ad6: FAILURE - ATA_IDENTIFY timed out
Dec 17 03:24:49 darkstar kernel: ad6: deleted from ar0 disk1

Dec 17 03:24:49 darkstar kernel: ad6: WARNING - removed from configuration
Dec 17 03:24:49 darkstar kernel: ar0: ERROR - array broken

And "atacontrol list" even shows all disks, here the output
ATA channel 2:
    Master:  ad4 <ST3200822AS/3.01> Serial ATA v1.0
    Slave:       no device present
ATA channel 3:
    Master:  ad6 <ST3200822AS/3.01> Serial ATA v1.0
    Slave:       no device present
ATA channel 4:
    Master:  ad8 <WDC WD2000JD-00HBB0/08.02D08> Serial ATA v1.0
    Slave:       no device present

These 3 Disks are my stripe set!

Is there a way to recreate the stripe set without losing the data on the 
disks?

I think there must be an easy way, because e.g. ill take these disks to 
a friends computer(with the same controller) it should be possible to 
use my raid on his machine, right?

 I am running 5.3-RELEASE with a Promise TX 4
