I installed three 1TB drives in a RAID 5 and have a separate drive for the OS. Everything is working properly and shows up as expected in the BIOS boot screen, however in windows (Vista 32) I now have an icon near the clock/taskbar that lists the three RAID drives as "removable". It is the same icon that is used when you plug in a USB drive to allow "the device to be safely removed".
I did a google search which turned up a similar question where the answer was to uncheck "removable drive" in the drives properties box. I don't have that check box in my drives' property box.
I'm not too concerned about this, but it doesn't seem right as these drives are not removable. Is this normal for a RAID setup? This is the first time I have used RAID.
