I'm somewhat against the use of this program on MP4 players since there's the risk of overwriting the firmware if the flash is really smaller than it specifies. There's also the fact that flash these days, unless you're lucky and get a 100K cycles SLC, has very low endurance (down to 1,500 cycles for some very new parts). It's OK for USB drives and the like, which don't store firmware on the same flash as the main storage. The better way is to open the device and read the part number directly.
