I looked around the archives a bit, but didn't see anything like my quandary. I have a late 2006 24-inch iMac/2.16GHz with a nearly full 500GB (at roughly 466GB full) hard drive. I managed to get a WD 2TB backup drive installed a few months ago, an upgrade from a Iomega 750GB unit. Having never opened up the iMac, but looking at the hardware under the Apple logo in the upper LT corner, info says the HDD vendor is Intel ICH7-M SHCI model ST3500641AS Q. I would like to upgrade the computer's hard drive to a 1.5 or 2TB, if it is possible. Can anyone help and possibly steer me towards a 'How To'?
