Do you mean the threads are stripped? If so, you could try putting a little blob of something sticky (like bluetac?) into the head of the screw then put the torx driver in and as you unscrew try to gently pull the bolt out at the same time. HTH
What size? If it's a 12" the answer is here. http://tinyurl.com/yca8bsy For some reason the title of the page is wrong (it thinks it's about changing a master password!) but the instructions are how to change the internal drive in a 12" powerbook. Cheers, Kwackman
Hi Mayer, Thanks for the reply. I didn't know you could boot from an external drive! I'm off to find an firewire drive to try it. Getting my hands on an ext. firewire DVD might take a bit longer. I'll report back any results. Thanks again for the response, much appreciated.
