I have a MZ-NHF800 which I bought over the net from a store in Canada a few months before hi-md's hit the UK market. It came with Sonic Stage 2.0 which I was using very happily on my computer at work. My computer was upgraded, the new one was installed with windows xp professional. I re-installed SS 2.0 only to find that it would no longer recognise my 1gb disc and I then discovered that it would not recognise any of the normal 80 minute discs that I had formatted to hi-md. Any normal net md disc using sp, lp2 or lp4 is recognised in the usual way but trying to use SS to format one of these discs to hi-md causes SS to chunter to itself for a moment and then do nothing. I have since downloaded SS 3.1 but it is behaving in exactly the same way. I am a big fan and an apostle of MD as a format and I really miss my single disc with 40 or so albums on it - but to tell you the truth I am now seriously considering giving up and joining the iPod herd! Can anyone give me any help to get it working before it's too late?
