My NetMD (MZ-N1) has decided it won't transfer files properly any more. It looks like it has worked but when I try to play them back they are mute. They seem to take an age to start playing and the time display will periodically freeze. If I remove the disc and put it back it shows as a blank disc. In fact, if I add one file to an older disc that works, eject it and replace it, it is now blank - even the older songs that were playing fine have gone. I have removed OMG2.2 from my WinXP PC and installed Sonic Stage as per the instructions given elsewhere but the same thing happens.
Any thoughts?
