FlashGenius, an easy way to see if memory is hacked;.
 

The download link is here.

Open up your MP4 player, and look for the memory chip and write down the serial number.
It looks like this. <- Click, large picture!

In this case it is: K9HBG081UM

Now start FlashGenius.

You can see that in my case the real memory was 4GB and not 8GB.
