My iMac 2011 was making loud clicking noises so I downloaded S.M.A.R.T drive checker and it said my HDD was failing. Is that probable and if so will I have to replace it? Thanks
Yep sounds like a bad hard drive, it would need to be replaced.
If you have Applecare or some other third party warranty it should be covered.
If not, Apple can still repair it but you may be charged for repair. you can replace the drive yourself too and there are numerous guides on the internet which show you how its done
