hard drive size?

i just got an imac and the hard drive is not 250 gigs its only 232.
do any of you who an imac with a 250 gig hard drive have the same situation. i say i am missing 18 gigs, where are they? they sure arent part of the installed software cause i already check.

did apple rip me off with 18 gigs or am i not reading the fine print?

That should help explain it

250,000,000,000 bytes = 232.83064 GB

basically HD makers use base 10 (which is what people use) where a computer can only use binary

Thanks for the info.
we should join the class action lawsuit. i got thousands of songs and pictures and missing out on 18 gigs does not help!

The article on the suit was a few years ago. Every hard drive box and computer box listing specifications explains the math that i posted above so they aren't liable

i missed the fine print!
oh well. we live and learn everyday!
i think!
Thanks again for the info.
