This problem is affecting 3 of 4 my computers running XP pro with SP-1. I can insert a floppy disk and it isn't recognized as being formatted; and if given the option to format, the formatting fails. This occurs with new formatted disks as well as with known good disks. Sometimes, for whatever reason it decides it likes a disk and will read it. I've tried three different floppy drives on one computer to no avail. I've tried disabling Norton's 2004 and that has no affect. However, I can take the same bootable floppy that won't read while the computer's running and boot the computer with it succesfully, which leads me to believe that its OS related. Any ideas or suggestions would be appreciated.
