MBP mid 2012 500GB HDD needed fresh OS install due to failed update 12.13.3
Tring it with bootable USB mounted High Sierra 10.13.3
Erasing possible with MS-DOS, but not with Mac OS Extended (Journaled) or APFS*
It has issues with mounting while erasing:
MacBook Pro (13-inch Mid 2012), macOS High Sierra (10.13.3)
If you're certain you booted into the flash drive I don't know why you are having a problem. Of course you could boot into internet recovery and try installing from there.
I have tried that (Internet recovery, using CMD+R) also at least thrice...
With that also some or the problem pops in
That being quite slow (takes more than 4-5 hours), thought of booting from bootable USB
Internet Recovery keys are Command+Option+R. If you have installed macOS 10.12.4 or above this key combo will boot to the recovery Utilities Menu and let you install the OS that is currently supported and available for your Mac (e.g. 10.13.3).
Shift+Command+Option+R combo boots to Internet Recovery Utilities Menu so you can install the most current version of the OS that shipped with your Mac (e.g. 10.11.6).
As CountryGirl56 noted, you should be able to boot to something external (e.g. Internet Recovery) and select the Apple HDD HTS.... media (disk) not disk0s2. Run First Aid to see if there are any errors that need to be fixed. Then keep it selected and click Erase to create/format a single volume.
I got the trick!
While erasing the disk, unplugging the bootable USB did the job
Though, I do not understand why...
Thanks @CountryGirl56 & @keg55 for addressing to my problem [was stuck up here from last 2 days!]Hopefully, I would now install fresh copy of High Sierra
Try erasing the top level of the drive. GUID/Mac OS Extended (Journaled).
I am not able to...
Every time the same error message appears
Is there any other way out to erase/format...
Maybe someone else will have an idea. Of course it's possible the drive is failing. But see what someone else has to say.
