Please check the followings:
1. Did you error-check your hard drive?
-This happens mostly after using hard drive then formatted. Sometimes, the > hard drive usage doesn't fix that fast or will fix after you finish
error-checking the drive. You can error-check by right click the drive ->
Properties -> Tools -> the first option should be error-checking.
2. Is ANYTHING in your hard drive?
-When I first bought this computer, some programs were in use because of
backup and extra pre-installed programs. Of course, I assume that you have
installed an "empty" hard drive, but you might want to format to make sure
nothing is in the drive. If it's in use more than it should be, the only
thing I can say is it's for NTFS stuffs.
3. Did you calculate your hard drive in binary way?
-I have noticed my recently bought 40GB PEHD has about 2.5GB less than it
says on the cover of the product. Now, the company DID make 40GB, as in
40,000,000,000 bytes. But here's a thing. The computer doesn't calculate 40
billion bytes as 40GB. Instead, it calculates in binary way.
-Binary calculation may sound complicated at the first place, but you'll get
friendly...hopefully...Anyways, the main calculation is
2^0 for Bytes,(B)
2^10 for KiloBytes,(KB)
2^20 for MegaBytes,(MB)
2^30 for GigaBytes.(GB)
If you are familiar with math, "^" means power, which means 2^10 is 1024, or
2*2*2*2*2*2*2*2*2*2. The easiest way to calculate binary size is find the
size in Byte first. Let's say your hard drive is exactly 160,000,000,000
bytes. As I wrote, I will divide 160,000,000,000 by 2^30, because it's for GB
calculation. My calculator gave me 149.0116119384765625 GB, or simply 149GB.
Don't be sure your hard drive is almost 149GB because I just calculated.
Check your hard drive's size in Bytes, then you calculate it. This is
probably why the file properties show size in Bytes.

I have just installed a new 160gb hard drive but windows only recognises 127gb.
I run xp sp2 fully upto date I have installed Maxtor 'big drive enabler' and
still it says 127gb despite saying that the 48 bit LBA is installed?
I am considering re formating but that might not make a difference.
