The PERC H700 is the only Dell controller that will support larger than 2TB drives, and a firmware update to the latest is required.
PowerEdge R510 Adding a single 3TB sata drive. Added to CADDY, inserted into SERVER. Orange Light started flashing after a minuite. This was the first indication of life. Cannot see the drive from OpenManage , Enclosure Backplane , Pyhsical Disks. Any idea what i am missing ?  Thanks for any help, driving me nuts. Scott
