I ran that program and it said around 10GB were corrupted but i havent been able to complete the full diagnosis because the sansa unplugs itself from the computer after around 2 hours. Is there something I can do to fix this? Also, I’ve had the sansa plugged into the computer for almost a day now yet when I took it out there was no battery in it. As both the sansa and microsd are acting eratically,it may be more helpful at this point to know what I did wrong in the first place in order to avoid something like this again if I decde to purchase a new sansa.
Also in reply to your questions, there is no physical switch on the microsd and i have been accessing the microsd through the sansa itself.
