What happens to some of data when a hard drive says "actual formatted capacity is less"?

Answer 1

Here, this article should help you to understand the process more.

Answer 2

The actual formatted capacity actually tends to be more than advertised.

The problem comes about because most computer operating systems (including Microsoft Windows) have a bug whereby they assume that a kilobyte is 2^10 bytes, a Megabyte 2^20 bytes and a Gigabyte 2^30 bytes while in actual fact a kilobyte is 10^3 bytes, a Megabyte 10^6 bytes and a Gigabyte 10^9 bytes.

The Hard drive makers do things properly and use the correct meaning of the prefixes but this results in the advertised (and actual) capacity of the hard drive being different to the incorrect reported capacity from the operating system.

There are a set of binary prefixes that are available to be used but aside from a few open source programs very few people actually use them instead choosing to abuse the SI prefixes which are NEVER to be used for base 2.

The formatting of the hard disk and all the stuff needed for a file system put on a hard disk to be able to work does take up a bit of overhead but the hard drive makers leave enough extra for that so you still tend to get more than they actually advertise it as holding.

Answer 3

confident, like maximum computing device products, the actually volume of storage is decrease than the finished means. A "4 Gigabyte" gadget, working example, holds much less that 4 gigabytes of music simply by want for formatting area and different issues that take in a number of the gap. They placed that "warning" there to purpose to stay away from being sued once you hook it up on your computing device and it says 3.seventy 9 obtainable even however you have not placed something on it.

Answer 4

There are a couple of answer to the question but I think what you are looking for is: There is overhead needed to manage the files on a harddrive. That overhead will lower the usable space on a drive when formatted. The raw space will always be greater but most people will never acces a harddrive unless it is formatted but the manafacture always like to advertise the raw size of the hard drive.

Answer 5

the data is compressed u dont loss any of the actual information it's just compressed to take up less space.
