    So I got a brand new iPod classic, 120gb, turn it on, without even registering it, and it says only 111gb's are available? Uhhhh what happened to the other NINE gb's? I know the advertised size isnt always accurate, and that the OS takes up some space but... NINE gb's?!

    The problem lies in the fact that, for drive manufacturers, 1 GB = 1000 MB, whereas for operating systems and software, 1 GB = 1024 MB.
    Likewise with MB and KB. Therefore, 1 GB (as the label on the box shows it) is 1,000,000,000 bytes, but 1 GB (as your computer shows it) is 1,073,741,824 bytes.
    Therefore, your iPod is 120 GB by the standards used by manufacturers, but only 111 GB as iTunes shows it. It's still the same 120,000,000,000 bytes though - it's just that the 111 GB that iTunes shows are bigger GB than the GB on the box...

    1) Take a look at every post above, and HAVE YOU EVER USED A HARD DRIVE BEFORE?

    2) Try having an "8GB" iPhone, which is only about 7.1 GB. It's a shame that the manufacturers don't have to put the actual capacity because I could really use that extra space even though I know it's not there.

    Real 1GB = 1,073,741,824 Bytes
    Advertised 1GB = 1,000,000,000 Bytes = ~953.67 MB
    Loss total = 73,741,824 Bytes = ~70.32 MB

    Real 100GB = 107,374,182,400 Bytes
    Advertised 100GB = 100,000,000,000 Bytes = ~93.13 GB
    Loss total = 7,374,182,400 Bytes = ~6.87 GB

    Real 1TB = 1,099,511,627,776 Bytes
    Advertised 1TB = 1,000,000,000,000 Bytes = ~931.32 GB
    Loss total = 99,511,627,776 Bytes = ~92.68 GB

    Real 1PB (that's 1024TB) = 1,125,899,906,842,624 Bytes. And if we're still using the same system by then...
    Advertised 1PB = 1,000,000,000,000,000 Bytes = 909.5 TB
    Loss total = 125,899,906,842,624 Bytes = 114.51 TB = 117,253.43 GB

    Hard drive makers really have to get their crap together about this, or eventually we're going to be buying petabyte HDs with 114 TB missing.

    Here we go again...
    So your last iPod was exactly what the badge on back said?

    I made a thread awhile back almost about the same thing, except I had a reason to be dramatic because it was like 45GB I lost, but I later came to understand that there was reason for it. I hope my thread helps you.

    Not really, computers need to start properly recognising SI units. A gigabyte is a billion bytes, no more, no less. They need to start using binary prefixes instead of SI prefixes on the computer.

    Seriously, what do people have against searching? Is it really a huge imposition to go and click search and type in what you're looking for. I'm sure you use Google on a daily basis. So why can't you search on MacRumors? It doesn't take a Ph.D to search on MacRumors...

    Wait, apparently it does.

    Here's an idea: Round down. Sell it as a 110GB hard drive, and when the buyer plugs it in, they'll be surprised to see that there is an "extra" 1.76 GB to use.

    Exactly. 1 GiB is not equal to 1 GB. The real problem here is that people in the computing field took the SI units and changed their values without asking anyone.

    Last time I checked, 1 km didn't equal 1024 meters.
