Thanks everybody for your help.

Bob, your codes worked fine except for the one that gives the drive
size. That is because the Microsoft WMI scripting Library is not
installed with Windows NT. I found another solution at the
www.allapi.net website that "tolgag" mentioned. What a fantastic
resource that is.

Thanks again.

Library and run this simple routine
