Alright about a week and a half ago my Macbook Pro started acting up. All of my applications were crashing randomly and what not so I decided to just try and reinstall El Capitan onto it. I tried and tried and tried but only got an error about how it couldn't be installed on that computer.
So then I went and completely reformatted my hard drive and booted up with Internet Recovery. Told it to install Mac OS X Lion again (that's what came with my computer) and I am now getting the following errors when I look at the installer log:
Line 1: Install Mac OS X Lion : Chunk validation failed, retrying...
Line 2: Failed to verify InsallESD.dmg: hdiutil verify failed
Line 3: Damaged resume data :/Volumes/Samsung SSD 850 EVO 250GB Media/Mac OS X Install Data/InstallESD.dmg.partial : /Volumes/Samsung SSD 850 EVO 250GB Media/Mac OS X Install Data/InstallESD.chunklist.partial
I'm leaning towards the conclusion that my SSD has gone bad even though it's only a little over a year old.
However, I thought I would post here too in case anyone else has had this problem and was able to fix it without getting a new hard drive.
It's also worth noting that when I use Disk Utility to check the disc for errors it doesn't find anything.
I just tried to install onto my old mac hard drive and I'm getting the same error. After some more research I saw that some say if you upgraded ram to take out the ram from one of the slots and try again. I'm going to try that when I get home and see if that works.
