tools like WMI when used with kix4.0 can give you this information.

a small example.

code:
$drives = GetObject("WinMgmts:").InstancesOf("Win32_LogicalDisk")
for each $drive in $drives
	? $drive.name
	? "Total drive size = " + $drive.size
	? "freespace        = " + $drive.freespace
	select
		case $drive.drivetype = 0
			? "Drive type       = Unknown"
		case $drive.drivetype = 1
			? "Drive type       = No Root Directory"
		case $drive.drivetype = 2
			? "Drive type       = Removable Disk"
		case $drive.drivetype = 3
			? "Drive type       = Local Disk"
		case $drive.drivetype = 4
			? "Drive type       = Network Drive"
		case $drive.drivetype = 5
			? "Drive type       = Compact Disc"
		case $drive.drivetype = 6
			? "Drive type       = RAM Disk"
	endselect
	? ""
