Done.

how would that make any difference?

Manufacturer says his HDD has 160GB; but calculated with 1000^3 Bytes = 1GB.
Program on computer calculates correctly with 1024^3 Bytes = 1GB
-> 160 GB [Manufacturer] ~ 149GB [Computer].
So forget about it. The difference is far beyond 204MB ::)
boxerorange:
Why would Apple make it larger than 204MB? That's plenty of space for their firmware, what else could be stored here?
Llorean:
Suspend image. At least that's one theory. Firstly, their firmware is quite large on the players we're familiar with, but the fact that the 64MB RAM players have a larger firmware partition than the 32MB RAM ones suggests that it's probably there so they can hibernate the RAM of the player to disk when it goes into deep sleep or such. It's also probably a good deal of reserved space for future ideas (for example, when the iPod+Nike came out, that installed a chunk of data to the hidden partition as a resource image for the Nike hardware).
GodEater:
Given that the iPod Touch is functionally almost identical to the iPhone (which I own and therefore feel somewhat qualified to speak about), I can say that on the Touch at least the "firmware" is actually a cut down version of OSX, which runs at a great deal more disk space than the firmwares from previous iPods.
I've read in a few places that the Classic is also running something similar to this cut down version of OSX (though unfortnately I can't cite the places I saw it as I forget, and it was pretty vague there anyway).
This would likely mean that the firmware partition will be significantly larger than in previous iterations of the iPod.
Certainly on the iPhone the "System" partition where most of the OS lives is around 300MB.
