[QUOTE="pigoo3, post: 1895461, member: 56379"] Congrats that booting from the High Sierra flash drive works. But...this is really not a boot disk in the sense I've been describing in this thread to test the 2014 iMac's internal drive. This is just a macOS installer drive. You need an external HD or SSD that you can install the macOS onto...then run the computer from this HD or SSD for normal day to day computer activities (this is how you properly test to see if the internal HD is failing). From what's been described...what's being done now is High Sierra is being installed onto the "potentially bad" internal hard drive. This is not the way to test if the internal drive is bad. Sure this can be done just to see what happens...but if the internal hard drive is worn out...this isn't going to help. Hard drives have mechanical moving parts inside...and just like anything with moving parts...sooner or later this parts wear out. This could be why the internal drive is having problems.
