Water cooled My Problem I have two SATA drives installed in the system a 160GB drive and a 500GB drive. The 160GB drive has windows installed on it and windows boots fine and works perfect. The problem is windows cannot see my 500GB drive, the bios sees the drive and even windows "Disk Management" can see it, although when I right click the drive in "Disk Management" I only get the options to set a new partition, properties or help and in properties the volume properties button is grayed out. So how can I resolve this?
