i allways thought that hard drive manufacturers saw 1gb as 1000mb
but windows sees it as 1024mb
so therefore you loose 24mb per gb
and you loose 24gb per Terabyte
and you loose 24tb per Petabyte
ect, ect, ect
oh and just cos i know the amount of gb in a Zettabyte im gonna post it here
Zettabyte =1,099,511,627,776GB
wow just looking on this site i have found out why they have diifernt sizes
Although data storage capacity is generally expressed in binary code, many hard drive manufacturers (and some newer BIOSs) use a decimal system to express capacity.
For example, a 30 gigabyte drive is usually 30,000,000,000 bytes (decimal) not the 32,212,254,720 binary bytes you would expect.
When used to describe Data Transfer Rate, bits/bytes are calculated as in the metric system
if you would like to look up some more on the information the lik for the site is
