sorry man, that's normal. NOTHING is the size that is advertised. Its all in the math. if you google your questions there's a ton of articles on this. I use to work for apple and got a TON of calls on ppl complaining their 16gb iPod only shows 14gb lol. It sucks, but like I said its because of bits vs bytes. your drive is fine :)  hope this helps

500GB = 465GiB

500.000.000.000 bytes / 1024 / 1024 / 1024 = 465,66 GiB

+1, the HD companies calculate HD sizes in KB, MB, GB and TB which are respectively 1000, 1 000 000, 1 000 000 000 and 1 000 000 000 000 bytes (powers of 1000) as most OS/software/rest of the world report the size in KiB, MiB, GiB and TiB which are respectively 1024, 1 048 576, 1 073 741 824 and 1 099 511 627 776 bytes (powers of 1024).

The HD companies are actually the ones "right" when they use the decimal system prefixes Kilo, Mega, Giga and Tera, but again, they went against the domain's "convention" in doing so. It used to matter very little, you were "loosing" only 48MB on 1GB, but as sizes get bigger, so does the (relative) gap; on a 2TB drive, you "loose" about 200GB ....

Recognize that you are NOT "LOSING" space. 500,000,000,000 bytes is called "465 GB" by Microsoft just because their definition of "GB" is bigger than 1,000,000,000 bytes. And when they tell you your file size is 1.340 GB, they are using the same "Big GB" definition and your file really uses up 1,438,814,044 bytes.
