    Finally got more storage, nice new 1Tb samsung F3, the one that replaced the F1 103UJ model. Yet it annoys me that before I've even used the hard drive, i wont be able to use 69.41GB of that storage space, because its lost in the mystical world of formatting, and setting up ntfs. Actually the real reason is a bit more technical than that, and although i due know the theory behind it, Its somewhere at the back of my mind, I even think CPCmag wrote an article on it. Anyway it just annoys me that i wont actually get 1TB from the drive,, i don't see why manufactures can't just produce a drive, that after formatting and all that crap you end up with 1TB to use!!!!

    Gahhh

    It's not lost due to formatting - it's lost due to marketing.

    In the computer world, a jump of three orders of magnitude is a binary 2^10 = 1024; hence 1KB = 1024B, 1MB = 1024KB, 1GB = 1024MB, and 1TB = 1024GB. But to HDD manufacturers, that same jump of three orders of magnitude is a decimal 10^3 = 1000; hence (in their world) 1KB = 1000B, 1MB = 1000KB, 1GB = 1000MB, and 1TB = 1000GB.

    So if you buy a 1TB drive, you think you're buying 2^40 = 1,099,511,627,776 bytes of space, but they're only giving you 10^12 = 1,000,000,000,000 bytes of space, or 90.9495% of a logical terabyte. There might be some slight fluctuations depending on what the actual areal density of the drive is, but that's basically how they can get away with giving you less than you thought you paid for.

    Tis exactly true, I noticed this when my 8GB iPod and 8GB USB Pen Drive both seemed to have the exact same capacity, 7.45GB, I did some maths using a calculator,
    8,000,000,000 bytes = 7,812,500Kb = ~7,629Mb = 7.45GB

    So they are selling you 8GB as 8 billion bytes, but it isn't it is, like the above said = 8* 2^30 - 8589934592 bytes (Because 2^10 = 1024, and your multiplying by 1024 3 times = 10*3 = 30)

    Actually, when its in base 2, it should be KiB, meaning Kibibyte, as kilo is a prefix for base ten, so whenever you speak on memory etc, it should be KiB, MiB, and GiB, but for HardDrives the correct unit is actually KB, MB and GB.

    Scan's Knowledge Base explains it fully.

    now that bit i deffo know about, especially explaining broadband speeds to people IE 10mb connection from virgin, only showing as 1.04Mb/s when downloading a file etc.

    and meh i was just annoyed, because its a lie they get away with, and i know what i buy isnt exactly what it says on the tin, but nothing i can do about it. Anyway i've now gota sort out a gfx issue. If i cant get it sorted, you may see a post about it shortly, lol

    you haven't lost anything. it doesn't matter what manufacturer you buy from, it is the same size. in hard drive manufacturer terms, 1TB is defined as ~930GB. that's just the way it is. get over it.

    Yes because that 16GB iPhone (or other "iProduct - LOLZ all the way to the bank"™) doesn't register as 14.9GB or whatever it is.

    It doesn't matter where you get your storage it really is all the same lie.

    Whoop de frikkin doo... Someone figured out that if they put KiB's/MiB's/GiB's in there then 16GB storage would OMGBBQROFFLES up to 16GB when it's plugged in!!!!!oneone rather than being stolens! :eyebrow:
