Absolutely fantastic faultless guide. Thanks so much! I succesfully installed a Western Digital 2TB SATA drive to my mac to replace our completely failed drive. I had absolutely no issues, although I could have done with some double sided tape to secure some of the sponge (use ordinary tape doubled over in the end.
I also found 2 ordinary suction cups fromone of those little pull down sun blinds in the car were sufficient to pull the screen off.
All now up and running, fresh install of snow leopard and ilife downloading as I write.
Cant tell you how happy I am to have it all up and working again for just the price of the drive (bought from amazon) and some RAM as why not max it out (Crucial memory)
A small pointer for any who have the same issue. I put in an entirely new 2TB WD sata drive and then preformed a fresh install of snow leopard onto it. When I got to the section to choose which drive to install to there was no drive image.
I clicked at the top on disk utility, then picked the drive, clicked erase and erased the drive. THis actually formats it into a mac format. after this I closed disk utility and voila the drive was now visible and installation could commence.
