I Put together a system about a month or two ago, and I noticed when
I first booted it up that only 232GB showed up. It didn't bother me,
but now that I think about it, I wanna know where my other 18 Gig is!

Here's the specs
ABIT NI8-SLI Mobo
Pentium D 2.66 Overclocked to 3.2
Nvidia Geforce 6600
Soundblaster 5.1 Audio
Hitachi 250GB SATA
1 DVD Rom Drive
1 DVD+/-RW with Lightscribe

If you could let me know what I could do, to get the rest of my gig's
to show up. It would be great! And if you want to let me know what
you think about my system, you can let me know about that too!

There's nothing wrong with those numbers.

There is a difference between how harddisk manufactures use GB and how
Windows (or computers in general) handle GB.
Harddisk manufactures use this:

1 GB = 1.000 MB = 1.000.000 KB = 1.000.000.000 bytes
So 250GB would be 250.000.000.000 bytes
This is scientificly correct because K is Kilo and that means 1000,
and so on.

Computers work with powers of 2 (bitwise).

No they dont. That is only true of memory, not other stuff like
the cpu speed, comms speeds, hard drive sizes etc etc etc.

1 bytes = 8 bits (with 2 to the power of 8 = 256 combination)
And because of that, they thought 1000 wasn't a very good number,
bitwise, so let's make it 2 to the power of 10.
So 1 KB = 2 to the power of 10 = 1024

1 GB = 1024 MB = 1048576 KB (1024x1024) = 1073741824 (1024x1024x1024)
bytes 250GB would be 268.435.456.000 bytes

So 250 computerGB - 250 harddiskGB = 268.435.456.000 -
250.000.000.000 =
18.435.456.000
And in computer terms, this difference means about 18GB:
18.435.456.000 bytes = 18003375 KB = 17581,421 MB = 17,169 GB, so the
18 is probably just that number rounded up.

My personal opinion on this:
Harddisk manufactures know how computers work and what people expect
when they are saying Megabyte or Gigabyte.
So they just found a perfectly legal and scientific correct way of
cheating the customers!

Cant be cheating if its the SI standard.
