The PERC does not support non-RAID, so in order for it to be seen/used by the OS, it MUST be configured in a RAID array.  To use this disk alone, you need to configure it as a single-disk RAID 0.
I have four pyhsical drives attached to my RAID controller. Two are combined into a virtual drive, and one is a hot spare. All three of these drives are 500GB. I am having no problems or issues with these three drives. I also have a 4th hard drive attached to the controller. This is a much larger drive. The problem is that this drive does not appear under Computer Management when I boot into Windows 2003 64-bit Enterprise Edition. The one 500GB virtual drive does appear, and I have partitioned it into an operating system drive of about 8GB (the minimum) with the remainder for data. What do I need to do in order to make the larger drive available to Windows? At this point, this drive is completed wasted. I am attaching a screen shot of the RAID controller configuration. Because of size limitations, I had to post this file at a very low resolution, so it may be a tad hard to read. Drives #0 and #1 are 'online'. Drive #2 is 'Ready", and drive #3 is the Hotspare. Thank you.
