I have a media center PC running Windows 7 Ultimate with the following hardware:
MB: Asus P6T Deluxe V1
RAID controller: Promise FastTrak TX4650
Drives: (3) ST31500341AS
I have this setup as a RAID 5 with 3 TB usable. I have been using this drive with Windows 7 for about two months now. All of a sudden the drive shows as unallocated space. The RAID shows as functional.

This is the SECOND time I have had this happen with this hardware. The first time I was running Windows XP pro.

I checked firmware on the MB and RAID controller several times when I loaded Windows 7.

Any advice?
