I bought the MZ-R30 on its initial release to the European market and subsequently, as the tech has been superseded and prices fallen, have added several other portables to my collection, including my favourite the MZ-B10. Since 2005, I have been very frustrated at the MZ-R30's innate ability to erase track marks from three previously recorded full discs which all now initiate the dreaded error message on insertion "Blank Disc". I contacted Sony about this problem as soon as it occurred, as I had some precious live recordings I did not want to lose, but their response was a virtual shrug of the shoulders. So, over the years since I have bided my time and hoped that someone would eventually come up with a solution to recover 'lost' MD recordings.
I can't tell you how pleased I was to recently discover Raintheory's explanation of how to hack a MD deck or a Sharp portable and clone the 'blank' disc but can someone advise me how to hack the MZ-B10 or my MZ-R900 or even my original MZ-R30? Also, I'd like to know just how the track info came to be erased or lost in the first place? One of my prized discs, recorded at a private concert in Germany, had been played many times before I got the error message. Keeping fingers crossed and looking forward to reading replies from our learned members here!
