One by one or all of them at onc= e? It would be best to go to RAID/SAS BIOS and see settings there. Disk order should not change. Usually RAID BIOS will show warnings about missing disks or RAID state change but it should keep the disk order. Except when all disks are set to create one large RAID array. Then controller decides on how to restore the data on the disks. Also this takes some time until array is can get back to full operations. On a HP ProLiant server I also had to boot special CD with RAID utility to set up this controller in a way that was not possible from RAID BIOS screen. Anyways with this kind of play it is always best to create a backup in the first place. Good luck! :-) --=20 CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
