Driver needed for my samsung external usb floppy drive model number SFD-321U/PC2 many thanks ron

If your computer recognises "New hardware found" when it is connected to the usb port it could be better to have Device Manager find and instal the best driver from the many available on the internet but failing that an internet search produces many results...

If it is a USB external drive it should be recognized by your laptop, it worked for my dell floppy drive from xp to win 7 64bit, if it does not you should download the winxp driver and use it to install in win 7 when it does not recognizes the drive.

-select have drivers
-select downloaded drivers

it would give you an error of pop up saying drivers are not "signed" just go ahead a accept that and it should work.

Let me know if it helps
