[QUOTE="Rod, post: 1868614, member: 204485"] Does your friend have a "full" backup of the device. I ask because in the end the solution may well involve complete erasure and reformatting of the HD. If it is the original 12 year old HDD it may well require replacement, either way its data will be lost unless a bootable external device can be created with Disk Utility on board. So yes, you are on the right track. If you can find someone else with a Mac who would be willing to create a bootable El Capitan installer that may enable repair via First Aid but it's a lot of work if the outcome is that the HD requires reformatting due to bad blocks or corruption. Whatever you decide I would suggest that your friend save what he can of his data first. [/QUOTE]
