I suspect my hard drive is broken but would like to know if there's anything I can do before turning it to service.
I'm getting a prohibitory symbol when I try to start the iMac. In recovery mode, when I try to reinstall macOS it doesn't find my internal HDD. I tested Disc Utility to control the HDD, but getting "Error: This disc needs to be repaired using the Recovery HD. Click to repair disc." When trying to repair it, I get "Error: Could not mount disk."
I also get "Warning: Repair partitioning card failed when structures to fit the entire disk size were adjusted" when trying to repair it.
I've tried installing macOS on an external drive too, but the computer can not find my hard disk for some reason. It doesn't pop up as an alternative.
Anyone knows of any solution for these issues?
(The error messages aren't literally word by word as I've translated them from Swedish.)
