if one HD is UDMA33 and the other is UDMA66, they will both run at 33 if they are on the same channel

it says the hard drive is a 4.3 gb ultradma

ur right...
du you have IDE cables with 40 or 80 wires?
u need 80 for speeds from 66 and higher, your HD is 100

EDIT: but ur HD's should still run at 33 at least....maybe flash your BIOS or reinstall windows

im not sure how can you tell whether its 40 or 80....its the cables that came with the computer

Yeah, this is kind of a known XP thing, sometimes being as craptacular as it can be. Anyhow, try this... it involves the registry so be DAMN careful, backup the registry first and dont touch anything else not listed!! Anyhow, goto this registry key (start, run regedit):

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E96A-E325-11CE-BFC1-08002BE10318}\0000

then create a DWORD called 'EnableUDMA66' and set its value to '1' (means turned on). If you have that there already and it shows a value of '0' then set it at '1'.

when do you have to do this? my XP detected it automatically.
Is it only with older drives???
