the quick story is I have the top of the range 2008 24" iMac that had a HDD replacement a few years ago. OS has been updated to whatever is before Mavericks, snow leopard I think. I have to get it back up and running now and combine the pictures from my wife's MBP. Problem is the HDD is 650 GB or something of which 638 is used. Not good I know. I have a 1TB hybrid drive to clone too and then add her photos and then back the whole thing up on a 4TB raid drive. Should I bag the whole thing and buy a new iMac? If not then I need to clone this drive or just save necessary files which is likely 500GB archive of pics and video and do a fresh install. Can anyone help or point me to a tutorial for the processes I will need to go through. I realize it's a lot of steps and variables but because of that and me not being highly tech savvy anymore it's almost too daunting. I hate to bring it to Genius Bar and say "fix it" and just pay but I don't want to screw anything up. I will post machines exact specs but it has the top processed like 3.06 and maxed RAM which I think was 4GB back then.
