Technika mp-507. 4GB (not hacked) interesting glitch
 

My father got himself a 4gb Mp4 player from Tesco, and we did the whole lets format it and make sure it isnt hacked. It isnt, though it only formats in FAT32 and not FAT. That was quite a while ago so im not sure of the guarantee status of it now, but we've started noticing that there is a rather annoying glitch to it. When his battery dies, it corrupts pretty much the whole flash ram. Last time it did this (today) we went from the player being full, to 75 songs.

Anyone have an idea what might be causing this (if it's preventable)?
Would a firmware flash help it, do you think? More importantly, does anyone know WHERE to get firmware for it?

hey, sounds sort of like the memory is like ram lol. I accually have the opposite problem with one cheap player i got while charging songs get corrupted, so you charge then copy all the songs.

A firmware flash might help, but i doubt it as it seems like more of a memory/chip problem.
