Antwoord op "Flashing question mark after installing new hard drive."Hey there, I’m wondering if you could help. I’m having the same issue except I can’t use disk utility to repair or format the partition. The Genius Bar formatted my drive fine, but my laptop still can’t boot into the correct disk or even recognize it. When installing from disk utility, it can’t detect the drive either. Is it really my connector cable that’s wrong or is it something else?
