It's worse than that, though. If the player had 20,000 MB, it would store 19.5 GB. As it is, it only has 19,073 MB.

Ah well. I hate the way they calculate it all.

What usually really skews the numbers is that they always advertise the UNFORMATED size... when you add all the sector/track overhead, filesystem overhead, etc., that takes up a good amount of space (we're not just talking a few bytes...). (1.44MB floppies used to be advertised as 2MB Unformatted... until someone came out with 2MB formatted-capacity, they decided it might be too confusing)

On top of that, subtract the unusable space caused by manufacturer defects, that can cause two drives of the same make & model to have slightly different sizes, too.

Also not everything in computers these days rounds up to the nearest power of two (1024)--in networking terms it's usually 1MB = 1000KB, but disk storage it's was still 1024 (well, usually it is, anyways). They're just trying to confuse us all :)
