Hard disk sizes

  Diodorus Siculus 12:55 10 Jul 04

A friend who bought a 160GB hdd from Aldi (following my suggestion) says that after formatting it is only 151GB and wants confirmation that this is correct.

Mine formatted at 149 but she does not think that is correct. Any comments on what the disk should format as in NTFS (mine) and Fat32 (hers)? Any any links to reasons why are also welcomed.

Many thanks, Dio.

Manufacturers claim a Gigabyte is 1000 x 1000 x 1000 = 1,000,000,000 bytes.

In reality a gigabyte is 1024 x 1024 x 1024 = 1,073,741,024 bytes.

There fore when a manufacturer says its drive is 160GB then in relatity it is 160,000,000,000 divide by 1,073,741,024 = 149.01GB.

has hit the nail on the head.

It's the came with CRT monitors. They call it 17 inch, but the actual bit you can see is more like 16 inch.

Thanks guys; I knew that somewhere among all the rest of the data in my head. Like Homer Simpson, "when I learn something new, something old gets pushed out. Example: When I learned to drink wine I forgot how to drive." :-)
