I have a MZ-NH600D with SS 3.4 using Win 2k and Sp4. My problem is that When I go to transfer my music it starts to transfer the song, gets to 100% but doesnt say completed just says transferring, then stops for like 30 seconds and does nothing. and then the song disappears from the list of whats on my minidisc which is nothing on there. This started happened when I was transferring and took out the disc during transfer. I thought it was the disc but I got a new one and the same problem is happening. Also before when it worked the minidisc showed up on the taskbar but now it doesnt.
