R605 is a power edge server model I think.The Perc6/i is a Dell rebranded raid controller, it's actually an LSI in disguise. Try downloading the Megaraid utilities from LSI and using them to see the status of the card. Also, when you boot the R605, you should be able to get into the Perc's firmware for drive creation/maintenance. You might want to check there to see how it thinks things are configured and it hasn't decided the 750G drive is a hotspare or something (a hotspare wouldn't show up to the OS). I'm assuming all the drives are connected to the Perc6/i controller. Drives connected to the Perc controller won't necessarily show up to the BIOS.
