not full hdd capacity detected

[rish p]

got my new Samsung 160GB 7200rpm. it automatically formatted it as ntfs n installed win 2000 on it fine, workin like a dream BUT windows only detects 127GB. i had a look at sum otha posts wid da same probs but im at a dead end i think. ive changed da registry, no change. i looked at wot bios detects it at n its 130GB only. i looked around bios 4 a bit but cudnt find nethin bout 48 bit block woteva. i tried da maxtor big drive enabler but dat told me it didnt need 2 change my registry coz i already had dat 48bit thingy enabled. ne ideas? btw i hope i dont have 2 "flash" my bios or woteva coz i have a bad feelin dat i will f up my mothaboard. if dta is da only solution, is der ne way of gettin round dis prob as well??!!
