hi, i did a recording on Sony MD walkman MZ- R909 recently. After about 2 hours of intermittent recording, it suddently went off. Maybe the battery died down but when i started it worked again and worked for short while and later showed disk error. Looks like the low battery could have caused data damage. Now i am unable to capture the data from the minidisk recorder to the computer as it is not playing on the player. Is there anyway i can restore the data? Thank u.
