hi guys,

if you know how to uninstall hda fix v3 ,plz help..

I cannot boot after using hda fix v3

thanks

Same here! I had to reinstall 10.5.2 from disc. But at least all the users and documents didn't get wiped.

do this in terminal:
sudo -s
"your password"
sudo rm-r / System / Library / Extensions / AppleHDA.taruga
sudo rm-r / Library / Startupitems / LoadHDA

it should remove the HDA Fix

If you can't boot, try booting from the install DVD, wait for the installer GUI appears, click OK untill the menubar appears and chose > Utilities > Terminal.
In terminal type the following (not need for sudo when booting from the install DVD):

rm -rf /Volumes/Leopard/System/Library/Extensions/AppleHDA.taruga
rm -rf /Volumes/Leopard/Library/Startupitems/LoadHDA

replace "Leopard" with the name you given for your MacOSX installed volume (Partition or Disk)

Hope it will help you.
