I have a Teac USB floppy drive and another USB floppy drive, both have the same problem. I used it on three computers. One computer has Windows Vista and the other two computers have Windows 7, both computers bought in summer 2010. The floppy drive has been working well with Windows Vista and 7 until last week. Every time I put a floppy in the drive, the files on the floppy will show up, but then when I close the window and files I was using I would then eject the disk from the drive. I insert a new disk with different work on it. The disk drive will only show the old files from the first floppy and not show work on the current floppy (the second floppy). Also, I can access the files from my floppy without having the floppy in the disk drive. The disk drive is empty and yet I can still access files from the first floppy that was previously ejected. Which is crazy Please Help

Wow, I don't think I've used a floppy disc since Win98... How time flies. Anyway, while I'm no expert on modern use of floppies, it looks like your first floppy is cached (cached to the hard-drive/swap/page-file, that is). Have you tried refreshing the folder view (F5) with the other floppy in the drive?
