windows xp does'nt recognize

[bigcatchris]

i bought a 200 gig hard drive, and it shows up in the bios as 186 gigs, which i think is correct due to the way they count, well anyway when i boot up in xp it shows up as 127 gigs only, i was wondering if there was a way to fix this?

You can try installing the software provided by manufacturer or recommend by manufacturer. This might recognize the hard drive correctly.

its still not working, i updated the bios from the manufactor, i think its a problem with windows, i read an article on how windows only recognizes up 137 gigs, and it said to mess around with the registry. Thats something that i dont really know how to do.
