        Yeah I know it’s technically the correct use of terabyte vs tebibyte but it still feels bad when your 12TB drive is only 10.9TiB

          Well it is too bad the Windows sucks. If only they had the money to make a proper OS that gives you the option to switch from binary to decimal like in Linux.

    The OS uses 1024 and the drive manufacturers are using 1000.

    Which is why a 1TB drive shows 931GiB of capacity. (1024 GiB =1 TiB, 1024MiB =1 GiB, 1024KiB =1MiB, 1024 Bytes =1KiB) but the drive manufacturers using SI prefixes doing 1000 Bytes =1 KB, 1000 KB = 1MB, 1000MB = 1GB, 1000GB = 1TB.

    Thus the discrepancy.

      Which itself is for marketing reasons, a manufacturer would find it difficult to compete with others using units that make their drives look larger or cheaper at “same capacity”.

      There is also the smaller amount w!ndows will secretly waste for its own pleasure (few GiB iirc). And an even smaller amount that gets wasted in partitioning. Usually around 5MiB, you can reduce it to 16kiB with some manual configuration in gdisk, or you can skip partition tables entirely for some end-game cursedness. And then the filesystem will take some. ext4 takes based on the number of inodes, for large drives that can be tens of GiB. Btrfs takes almost nothing (though in the background allocates in steps of 1GiB, so some tools might show 2GiB used as soon as data is written). Then if you try to sum all files on disk, that will land even lower for many more reasons.

      Yeah:

      1000 GB × 1000 × 1000 × 1000 / 1024 / 1024 / 1024 = 931.32 GiB

      It’s a sufficient explanation. I don’t know why the meme has the highest IQ person say “I don’t know”, unless the joke is that it’s easier than explaining…

        Because there are other things that change usable space, like file tables, OS stuff, and bad sectors. The unit conversion is the biggest one, but not the only one.

        No, the problem is making up a new word (gibibyte) and expecting people to use it when there’s already a word for that (gigabyte).

        It’s the hard drive manufacturers that should change.

      At the beginning of time, K/M/G etc was based on 1024. This was considered a bad move by some people.

      What I don’t get is memory packages don’t come in thousands, but in volumes dividable by 1024, so why the 1TB=1000 somethings…

        Because back in the 1980s RAM chips were individually sold and the number of address pins exactly matched the 2^(# of pins) amount of memory addresses contained in the chip (for cost savings purposes) and only with the later column strobe addressing DRAM did that change but at that point they couldn’t deviate from the 1024 standard without getting sued (a couple did and went out of business).

        And since the RAM chips themselves are stuck using 1024 and the RAM sticks are made of matching RAM chips (for cost and performance reasons); it will remain that way until people start buying systems on a chip with embedded RAM.

      And it gets more complicated when we get to the metadata and filesystem structure. So, you technically never get to store 931GB, I wonder what the (average) ratio of metadata to data is? 3:1?

        Depends on the file system. If you are using FAT-8; it is 256:1 if you are on ZFS it is as low as 1:4.

        It also depends on composition of the data stored. If it is Linux ISOs; it is 4GB:64KB. If it is old C source code; it is 512B:4KB on ext4

    Has anyone ever used the last byte on any hard disc in a successful manner?

    I mean not by just putting a too large file there, but something that actually utilized that final byte and having the machine still run flawlessly?

        I already did it on floppies.

        I also attempted to program the entire AD&D rules as an Amiga Basic program. It ran well for a start, but then I noticed that the random generator always returned the same dice rolls. Turned out that the RAM was used up, so it couldn’t store the random value anywhere. The program was fine otherwise. Just out of ram.

        Anyway, I miss the ingenuity of having too little space, more than I am impressed with the possibilities of having too much.

        People simply did more with less. I want that to return. The bloat is obscene, and hopefully AI is going to break the balloon of it. Nobody really needs several gigabytes of code to run a 2 line program.

      The manufacturer is labeling the drive correctly as 1TB (1000GB, 10^(12)B). It’s Microsoft that incorrectly labels it as 931GB; it’s actually 931GiB (931 * 2^(30)B). A Mac will correctly show 1000GB and a Linux machine will correctly show 931GiB.

          I’ve seen GB sometimes on Linux, but they’re actual GB, not mislabeled GiB, so I don’t have a problem with it.

            If any company could get away with labelling their product to have 1/10th less and get away with it, they would. Usually consumer rights organisations fight to make it so that you get what is advertised.

            The producers are using semantics to give less. I, as a customer want what I have been promised by the label.

            If you’re interested in arguing the opposite, you’re anti-customer, and pro-ripoff.

      Plus some programs showing space actually usable for your data (not unreasonable from user perspective), which means another chunk is gone as overhead from the file system.
