It's an 80gb Western Digital, but only 74.52 of the hard drive is being recognized.
Thx in Advance

Yep, that'll happen with every single hard drive ever made. Although it's labeled as an 80 gig hard drive, due to sector divisions and other quite complicated reasoning, you're never able to use 100% of any hard drive's advertised space. For example, I can use 17.6 gigs of my 20.5 gig hard drive, and ~36gigs of my 40 gig hard drive. It's just a fact of hard drives.

Here's the math behind it.

Disk makers define a "gigabyte" as 1 billion bytes. So an 80 GB drive is 80,000,000,000 bytes.

Computers define a "gigabyte" as 1024*1024*1024. That's (calculator) 1,073,741,824 bytes.

So an 80 "GB" drive would actually be 80 * (1000000000/1073741824) = 74.50580596923828125 GB as reported by the computer. Looks like you got a couple megs extra

Precisely!! Thanks for the breakdown!
