Rainydays is correct, and for future reference, you can multiply the advertised size by .925 and get a good approximation of actual formatted usable size.

Yeah, unless the disk capacity actually is correctly specified. I was surprised to find that the 140GB HDD I bought for my MacBook actually was 140GB :) But it's a rarity these days.

hey guys, just a quick one.....

just wondered what size exactly the 500GB drives in the new iMacs format to?

cheers
It is universal to any storage medium on any platform where manufacturers quote a Gigabyte (incorrectly) as 1000MB instead of 1024MB.

So to find the true amount, just multiple the given amount by 0.931

A gigabyte hard disk formats to 931GB - which looks terrible, doesn't it ?! :)

This really never goes anywhere; the prefix giga means 10^9 in all other contexts, which would suggest that its the storage media people who are correct, and the operating system people who are incorrect. It's not really ultimately an issue of correct or incorrect. They just use two traditional (but different) definitions.
