Hi, Today, when I connected my MZ-RH1 to my WinXP laptop in order to record to a Hi-MD disc, SonicStage came up with the following message: "Cannot use this disc as an audio disc because it was initialized by a program other than SonicStage. Click Properties on the Device/Media panel and initialize the disc to use it as an audio disc." The last time I used this Hi-MD disc was actually in SonicStage on the same machine, and it worked OK. I have added songs and albums to the disc now and then over a longer period. I have also tried to play the disc on my Onkyo MD-133 but gets the error message "Cannot read". Can it be a mechanical fault on the disc or cartridge, or is it a formatting error ? Has anybody experienced this problem ? Does anybody know how to get around this without losing the data/music on the disc ?
