Hey, guys. My Sony walkman player NW-S705F (2 gb) was on a format that I don't quite remember now... I dont remember if it wasn't FAT or FAT32 all i know is that is was a windows explorer format Anyway.. I tried to reformat it to do something and it didn't work for this other thing either but the thing is when i trasfer the music by sonic stage it says "Cannot transfer any more tracks. The memory of the device/media is full." when I disconnect it from the USB and try to turn it on, it displays "NO DATA!" but i think sometimes it has said "format error" too oh one more thing when i am in sonic stage i dont see any music but i went in to controls menu -> my device -> delete all tracks and it went to like 70 % and then it said this "failed to delete all tracks (error code:000066d7) What do I do /thanks for helping?
