I have just purchased a brand new Hitachi Deskstar 500gb SATA Harddrive.
When installed in my PC, I performed a NEW Windows XP installation. When it got to the point when it wants to fromat the drive, it tells me there is only 476gb available.
My question is - where is the other 24gb, and how do I recover it?
After all 24gb is a sh*t load of storage.
I have completed the installation, and don't want to start again if possible.

All comments welcome.

That is business GB compared to Computer GB.

1,000,000,000 bytes is one Gigabyte. You hardrive should have about 500,000,000,000 bytes. But Windows calls a Gibibyte a Gigabyte. A Gibibyte is 1,073,741,824. So there appears to be a loss in space.

This may be confusing but this may help explain better.

Thanks for your swift response.
Your comments and the article included does explain the reason why.
I just wish that there was an industry standard that everyone stuck to.
