Using a PERC 320/ DC controller with two 146G HDD, in a RAID 1 configuration.
I attempted to add two more 300G SCSI drives to the extra SCSI ports, somehow this affected the ARRAY.
I was still able to boot into Windows with one of the 146G HDD but not the other.
Put them both back in, From the RAID Management Software I set the questionable 146G HDD, which is in the 'ready' state, to 'Hot spare for the ARRAY'.
The rebuild started and ended 5 hrs later with an error.
Now the ARRAY status is impacted and the 146G HDD is stuck in the rebuilding state.
How do I fix this without loosing my data?
