Porrum_doctum

Hi, I've got an MZ-RH1 and used it for a live recording. All went fine, I listened to the recording on the way home and all was there. By the time I got back my battery was near dead. I connected the recorder to my laptop to copy my files (Vista, alas) and everything went wrong. I made a little well-known MD-player noise, then, to my astonishment flashed "blank disk". Oddly enough, when I check the diskspace, explorer tells me there's only about 270MB there, of which just a couple KB are used. Where's the other 3/4 of the GB there normally is? Is there anything I can try to recover data from this disk?
