Hello to all. I just bought a used sony mz-rh910 minidisc recorder but, as it came from ebay, it came with little else but the unit and the seller's recorded disc, so I'm trying to figure out how to use it. I went out and bought some blank discs to "start from scratch." I got to the gig to record, inserted said blank disc, plugged into the PA head and pressed record, only to get the message "No track." I tried the used disc, and it at least recognized that there was a blank track, looked like it was recording, but did not. So I'm thinking at this point that there must be a way to format a disc before recording. It would be best to start with a blank disc and understand how to use the thing. Any suggestions on formatting/best methods/techniques for recording from a PA head or mic would be appreciated.
