I was in process of erasing drive with Mac Disk Utility and by mistake removed cable. Now the drive will not mount. Disk Utility can see the drive but will not mount it nor can I repair it under any of the menus. Please help.
You corrupted it, you need to Erase it again to clear the corruption.
Thank you! I had tried erasing but the button was grey. So now I tried changing it from APFS to Mac Extended (Journaled) and it worked! Phew! Thank you so much! So fast too!
