Thank you for your suggestion - unfortunately there were check marks against all three (Use, Control and Modify). I unchecked them, rechecked and clicked Apply and OK and just for completeness rebooted as you suggested. Still unable to get recognition as the Adminisitrator of Drive D. I've had this problem intermittantly for some time but it has worked (I copied some photos on a couple of occasions) and, of course, it has worked when installing a small program from a CD on every occasion. So, don't understand why, when i try to copy a document it refuses to allow me access to the drive. Thanks again and any further suggestions would be appreciated.
