I feel very silly not having looked into it further in the period of time my mac was under the one year warranty. The drive works, but it take for me to eject it and put it back in 3-5 times until it stops making a noise. Not sure what it is. Does anyone know if they drive itself has a separate warranty from its respective manufacturer? That way, at least I would only have to cover labour. How much would I be looking at to do this job? I used to open up computers all the time, and I would do it myself but I am wary to try this on the iMac. Thanks for your comments. Bender.
