Hard drive capacities are advertised with a gigabyte meaning 1,000,000,000 bytes where as one gigabyte is actually 1,073,741,824 bytes. So when the drive is actually installed it will come up with the actual gigabyte capacity is opposed to the advertised "gigabyte" capacity. As you can see on your posted image, your drive has 249,995,624,448 bytes as it's capacity, which would be advertised as 250GB, but is actually calculated to 232.826569 gigabytes.

Yeh, basically, it's normal.
My 80GB disk only gives me 74.5GB
And my 120GB disk only gives me 111GB

The bigger the hard drive, the more "noticable" the amount it steals from you
I can't believe they still continue to get away with this... deceptive marketing. The only way a drive can be used at all is if it is formatted... and every file system has overhead. I believe I've read on hardware reviews as well that they tend to round up "just a few GB" sometimes even if they can't actually reach the exact number.
Yeah, you know my truck gets 200 miles per gallon dude!..... well, if it's run in outer space

It's not just the round-about size specifications of the hard drive, but it's also the file system headers that can take up a lot of space proportional to the size of the hard drive.
