Hi. I'm very ignorant about computers, so I'm calling out to the experts. I have two computers with Windows XP and Word 2000. I've always been able to transfer data through disks in drive A. Lately, either computer is likely to say that there is no disk in the drive, that the disk is not formatted, or that it can't be read and I should contact the system administrator. I'm using Staples IBM formatted disks--the Staples salesman suggested they were formatted for Macs and not for my computer's specifications. I tried formatting them on my computer, but it has made no difference. Any suggestions?
