Hi All, When I use my RH10 to voice record via a plug in mic, it records fine, yet when it comes time to playback or transfer via SS the screen says 'Disk format error, cannot record or play' and consequently the disc is wrecked and no longer works. (I've tried this with a few discs of different capacity and bands - in case it was a disc problem - yet it's done it each time. The thing is that it does it randomly, yet about 1 in 3 recordings do this and hence, I'm talking to myself about the same stuff over and over again and then trying to transfer to SS straight away before starting a new 'group' so as not to waste my time should the disc be wrecked! Has anyone else had this problem? Or perhaps have some advise? Also, where's the cheapest place to buy a new unit - i bought this one from ebay a couple of months ago. Thanks - Ryan
