    I just got a new HP w/ a 320gig hard drive. Well, before I even did anything to it, I took a look at the the space on the HD. It shows 288GB total and 254GB free. The only thing I have put on here are Norton, limewire, Yahoo messenger, and Full Tilt.

    I understand that some of the HD capacity will be lost to the OS and other components, but 32GB?! And how about 34GB being used up before I have even put anything on here? How does all of this work?

    Hard drive manufacturers define 1 gigabyte as 1,000,000,000 bytes while the computer OS used by most people usually calculate a gigabyte by dividing the bytes by 1,073,741,824.

    That and all HP's have a hidden recovery partition that is probably eating about ~20GB.

    If it has Vista installed, the OS can take up to 15% of the drive's space for System Restore. I've set mine to 2gb's to get back some of the drive.

    Yeah, its got the partition according to the guy at Office Depot. I havent dipped into that to check it. He said that it would give me the option to delete that partition once I make a recovery disc. Haven't done that yet since I don't have a dual layer dvd. I started it, but it says that it'll take 14 cd's to write to, while it'll only take 2 dvd's or 1 double layer dvd.

    How do I look to see how much that recovery partition is using up? And would that partition reflect as "used space" or will it take from the top and lessen what my computer shows as "total space"? I just did the quick math on the numbers from Sgt. Schultz.

    320,000,000,000 bytes would equal 320GB according to HD manufacturer. divide that by the number of bytes in a GB according to computer OS(1,073,741.824) and I get 298GB, so thats about right since my computer shows 288GB

    Before you do anything else you should make the recovery DVD's then store them in a safe place because you only get one shot at making them.
