This is a really strange problem. Windows 2000 has problems accessing my 3 1/2" floppy drive. If I try to access a drive through Explorer or a DOS box, Windows can't read the disk. At first I thought it was a bad drive so I removed it and tested it in another system and found it worked just fine. I then re-installed it in the system in question and found that I can boot to the floppy drive just fine. I then rebooted the system with a non-bootable disk in the drive. When I received the "Non-system disk. Remove and press any key..." prompt, I ejected the disk, let Windows start and immediately put the disk back in the drive. Since there is now a disk in the drive as Windows is starting up, it allows access to the disk from Explorer and a DOS box. It seems that Windows will only allow access to a floppy if it's in the drive when Windows starts up. Installing a disk in the drive after Windows is up and running doesn't allow access.
Any ideas?
