Replacing HDD iMac intel 27" with Samsung EVO 840 SSD
Currently my IMac late 2009 is reporting that the S.M.A.R.T. of my 1TB drive is failing. I'm opting to replace it with a Samsung EVO 840 SSD. Can I follow the same instructions that are given in the (very clear I must say) IFixit Hard Drive Replacement guide?
Will I stay clear of problems like excessive fan noise ?
Do I have to upgrade (from OSX 10.6.8 Snow Leopard) to OSX Mavericks first before I make a carbon copy of my hard drive.
I know these are a lot of questions all at once but I need to know them beforehand before starting any work on my Imac which I use as a professional photographer.
Thank you very much
