No, you can't use the MD as a disk drive.

I'm not sure if the new USB-compatible MD recorders will do what you want either - they're geared up for copying the music the other way, I believe.

If you've got an MD recorder it may well be better to record on that, physically away from the screaming fans in the computer (that's another problem, of course). Then just hook the MD line out (or headphone socket if it doesn't have a line out) to the sound card line in to transfer to PC.

By the way, for good sound it's far better not to get noise in there in the first place - noise removal software is really for rescuing noisy recordings that you are stuck with and can't do again (like live events or old records)
