2TB HDD Capacity

[vltr]

Hi! I bought WD Green 2TB hard drive a have only 1863.01 GB on it. As I found out that companies sell it like 1000 Mb per Gigabyte, assuming we have 2000 Gb and divide it by 1.024 GB we'll get 1953.125 GB. So where are those 90 GB that is left?
Thanks!

Probably need to take it all the way down to the "byte" level.

1TB = 1024GB
1GB = 1024MB
1MB = 1024KB
1KB = 1024B

How did you measure that 1863.01 GB ?

I got 931 GB in a hard drive view in my computer out of 1T drive so i guess windows calcs it to 1K so 3x division 1000/1024 i get 9,313... just about right.

The loss is actually due the format of the drive.
And the file system that has to be created to map all of the drive so data can be placed on it and retrieved.

The larger the drive in capacity the more space needed to map the drive.
The file system selected Ntfs or Gpt. and that is where the 90 GB went.
Plus the actual installation of windows on the drive if installed.

Yup, so the difference at the GB level is 1.024 ^3, TB would be 1.024 ^4.

Thats far from being true, HDD producers are using 1,000 measurement instead of 1024 as all guys said earlier, it has nothing to do with formating. We are not talking about small files using too much space due to block size or a size of MFT.

No, it is the binary, decimal difference.
