When you buy a new hard drive and insert it into your computer lower than the capacity written on the hard drive you can see that it has a capacity. Well why hard drive capacity is less visibleDoes the hard disk capacity seem low?
In fact, this is true not only for hard drives but also for all storage units such as flash disks and SD cards.
Why is hard drive capacity less visible?
Hard drive appears to be missing or hard drive does not show full capacity actually not a problem. That is to say;
Fixed disk manufacturers and Operating system programmers define Megabytes (MB) differently.
A hard drive manufacturer;
1 KB = 1.000 Bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB defines as
When used as storage capacity:
1 Megabyte (MB) = into one million bytes, 1 Gigabyte (GB) = 1 billion bytes, and 1 Terabyte (TB) = 1 trillion bytes equals.
When used as transfer rate or interface speed (USB, PCI etc.):
Megabyte per second (MB / s) = to one million bytes per second, megabit per second (Mb / s) = one million bits per second, and gigabit per second (Gb / s) = one billion bits per second equals.
Operating Systems programmers;
1 Megabyte (MB) = 1.048.576 byteequals to. (So 1 024 and its multiples calculated as)
Let’s talk about a 500 GB hard disk as an example. It disk’s unformatted capacity 500.000.000.000 byte‘is.
When calculated over the 1.024 system, 465 GB a disk of capacity is formed.
When you insert this disc into the computer, the operating system 1000’in not multiples 1024It calculates the disk in this way because it uses the multiples of.
In the table below How many GB Harddisk how many GB visible on the computer you can see.
