Thanks for your reply ^^
I downloaded the IOATAFamily.kext_10.6.1_Universal_x32_x64.zip file, them extracted it, used transMac to replace this kext in System/Library/Extensions/ But sadly that nothing was changed when i reboot with -f
The Mac OS installer did not show any drive in my conputer... i try DU, but it only the USB...
I think it is not a suitable kext for my laptop.
Please help!
