Added drive but not showing up

Hello everyone,

I have a Dell PowerEdge 2600 with a Dell PERC 4/Di RAID Controller. This unit holds a total of 6 drives but only 3 drives (RAID configured)are installed. The OS is Windows 2003 Server.

I installed a 4th (SCSI) drive but it will not show up. My goal is not to add to the RAID but use it as a seperate drive for online storage.

Any suggestions on how to make this drive appear?

Many thanks in advance.
