I currently have a Dell PowerEdge 2800 which has a 4 x 146Gb HDD configured in RAID5.
The disks are in the bays 4,5,6,7 (the bottom row). I experienced a problem where disk number 6 failed and the drive became degraded. After a couple of days of watching the orange light flashing and thinking it was repairing nothing happened and I decided to swap the disk for a new one. Still it did not repair so I tried recreating the array, formatting the drive and then restoring the image back to the drive. This time even with the disk in a different order the number 6 disk was still flashing an error.
What I would like to try now is to move all 4 disks into bays 0,1,2,3 - is this possible and can anyone point me in the direction of a good technical document describing the procedure?
