Don't know just what it is you're trying to copy but i'll assume it's an installed driver. Just use DriverMax to export any of the drivers you want to the media of your choice
Oh. You mean
1) that your computer is requesting a driver?
2) And it's prompting you for a driver?
3) And the prompt is defaulting for a driver on device A: (which happens to be your floppy?)
That means you need to 1) know what device is requesting a driver and 2) have the driver for it (whether on floppy or anywhere)
You can still download and use DriverMax to identify your device making the request. And as long as you're running 32-bit (not 64-bit) Windows it may just find the driver for you. Try it. (here's how to check 32 vs 64 bit Windows)
