[cassy309]

hello all i am having a bit of a problem i brought a extra hard drive which is a 160gb for my pc i already had a 20gb hard drive. i installed the drive but the entire size is not showing up in windows but when i booted into the bios the correct size was there. so i went to do some reading up on this and i found out that i may have to update my bios which i will do tomorrow and/or buy a controller card i would like some more information if any of you can help out by the way it's a western digital 160gb hard drive my 20gb is as well

remove the drive.

start windows xp.

then look into your registery if the follow is setting good:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Atapi\Parameters

look on the subkey "EnableBigLba" set him on 1.

shutdown your pc en install the hdd.

start-up your pc en format the drive.

i hope that this help you out of this problem.

windows xp have this problem when you install a hdd after the windows installation. sory for my bad english.
