A byte is the most practical measurement to work with. So at some point, one of the drive makes decided to use the 1,000k to inflate the space of there drives to give them selfs an edge on the market. file size, free space before and after file transfer). It establishes not only the units of measurement but even the prefixes.

Hard Disk Space Showing Less Than Actual

At that time, Intel was losing too much of the market too fast. This is why Microsoft has changed the terminology, from sector size, to allocation unit. As we can see in the screenshot below, nearly 11 GB of the hard drive’s space is reserved for a hidden recovery partition. Ask a question and give support.

  • For the first two I never saw the capacity in kB written on them.
  • but FAT 16 and 32 don't allow you to fully use the amount of space that's windows detects ether, but NTFS does.
  • There is a minimum capacity of "bits" of data the OEMs certifies the device's technology is capable of reliably delivering (at defined error rates and other conditions).
  • It later became an issue as having different definitions for a prefix led to confusion.

Might as well put a sticker on each box that says, "Comes with a $5 restocking fee, just for buying." Dario D., Sep 12, 2009 Dario D., Sep 12, 2009 Since it says "KiB" and not "KB", another person would know to multiply by 1024, and not 1000, to get the original value. So it is a number-trick (like the author wrote, a marketing trick) to sell you smaller disks for same price. http://hcsprogramming.com/hard-drive/space-problems-on-new-hard-disk.php For example, the MBR HD size limit of 2.2 TB (2 TiB) is not at 2.2 TB because someone today (or in the past) cut corners, but because it still nowadays

Difference between nationalism and patriotism Did Salazar Slytherin know the stone in his ring was the Resurrection Stone? Why Hard Drives And Memory Cards Have Less Space Than Advertised This allows the user to "low level" format the disk, which means re-writing the sectors physically on the disk. Let's blame everyone else, OSs, utilities, other software, computers, processors, flashcards, etc, because they are reporting a binary number as a GB, MB, etc, a convention that predates this particular IS.

Another trick was that they defined 1k (kilo) to not mean 1000 as everyone else in the civilised world did, but to mean 1024 instead.

Regarding actual drive size. The names kilo, mega, giga, and so on, have been slightly changed in this system to reflect that they are to be used with binary measurements.

Powers of 10 belong in decimal systems. ;) August 30, 2012 r One security issue with all this occurs when you decide to protect one of your documents. I bought a 2 TB drive, and was shocked (at first) to see Windows showing it as only 1.81 TB. kilobyte (KB), megabyte (MB), gigabyte (GB), terabyte (TB), etc., which are based on the SI units (binary prefixes based on powers of 1,000). http://hcsprogramming.com/hard-drive/used-space-free-space-on-hdd-erroneous-readings.php In fact, when looking for the total number of sectors on the label, you will see the number of sectors referred to as LBA, so it will say something like LBA:

If I were to round it to the nearest whole number, it would be 15 kB. thanks DID YOU KNOW?The scientific term for your fifth, and typically smallest, digit on both your feet and hands is "minimus".

Angered, we start cursing the manufacturer and our dealer for false marketing thinking that they should be sued for doing this. Is there a word for a statement which is false but comfortable to believe in?

The hardware manufacturer is giving you the proper size where K=1000, M=1000000 and G=1000000000. The OEM has no control over vehicle (car, truck, lawn mower, chain saw); conditions (hot, cold, high altitude); driver (grandma, racer, etc). Operating systems should either re-label the storage units to the binary prefixes, or start reporting the actual storage space (which I think Apple started doing with Snow Leopard).

It's kibibyte (KiB), mebibyte (MiB), gibibyte (GiB), tebibyte (TiB), etc., which are IEC units (binary prefixes based on powers of 1,024) vs. Your motherboard/storage controller needs to support 48-bit logical block addressing.

After installation and formatting I found out each Seagate was about 4gb smaller formatted. Like I said, its a rough estimate.
