iMac HDD Controller Board Fail

Hi.

I owned an iMac 21.5'' which I gave to my parents and the HDD controller board has failed. My parents took it to a repair shop, but they live in a remote area in Brazil, so they have no easy access to parts. I'm trying to buy the board over the internet and send it to them but I HAVE NO IDEA WHICH MODEL OF THE BOARD to buy.

I've tried making Google searches with key words such as 'imac late 2009 hdd controller board' or 'imac hdd board' but I get absolutely nothing of relevance.

Does anyone know which model I should be looking to buy OR does anyone know if there is a place I can actually find a list of specific parts for iMac products?

Thanks a lot.

The serial number on the bottom of your stand will give you the exact model if you look it up here, armed with that information you can get parts.

The problem may be your diagnostics. Why do you think the hard drive controller board (which is built into the hard drive is your problem? It might be better to give us your symptoms and tell us try to do the diagnostics.

Hi mayer!

Thanks for your answer.

The reasoning for the diagnostics comes from following:

- The computer wasn't booting so I ran standard system diagnostics, which indicated that my HDD was corrupted

- We then sent the computer to the local repair shop I mentioned previously and the technician installed a new HDD

- Regardless, the computer continued not booting and by running the diagnosis again the error messages were still the same

- The technician then concluded that the problem was in the controller board

The main problem here is that my parents, who now own the computer, live in a remote area with little access to direct support from Apple authorized partners and absolutely no access to parts. The only way to deal with this was for me to get involved and try to solve the problem by looking for answers on the Internet. Since I have access to these things (support and parts), once I find the answer I can get the parts and send them to my parents.

I just talked to the technician and he explained it's actually not the board which is built into the HDD but rather the board that's attached to the motherboard with which you connect the cable that comes from the HDD.

Well, that's clear as mud. Does this supposed board have a name? Is this the data cable or the power cable that goes to this board? Is this a real Mac Technician or some guy trying to baffle you with bullsh*t? Here's a blowup on all the parts in this machine, click on the parts diagram to expand it: http://www.welovemacs.com/mb950lla.html
