IBM gave me the wrong hardrive

[BestMoneyEverSpent]

so the computer i bought was suppose to come with a 100/7200 HD. i don't know why i didn't check this right away, but last night while installing word and excel i decided to click properties on my C drive.
it read 79.1 GB capacity. am i missing something...because that isn't 100GB. im now worried that i may not have gotten the 7200. how do i test the speed or figure out what it is?

and things were going so well....

You have the correct drive. Part of the drive is reserved for the hidden restore partition. And, capacities are quoted two different ways.

Manufacturers quote capacity with a 'K' being 1000. Operating systems and technical people use 1024 (or, 2^10). A drive with 100,000,000,000 manufacturer-quoted bytes will be reported by windows as 93 GB.

Then, subtract more for O/S formatting, partitioning information, etc.

My 100GB hard drive has a quoted capacity of 88.2GB. I don't know why your drive is reported to have 79.1GB, but it can't be a 80GB drive so it must be a 100GB.

thanks RonS, hope that wasn't too stupid of a question...but i certainly feel better now.
