Hard Drive Corrupted [duplicate]

Solution 1:

I had the same problem as you. After I erased via Disk Utility, I reset my Mac Air (what was i thinking, right LOL). Now it won't boot again. (Folder with question mark keeps blinking on a black screen). I waited for the Internet recovery to finish (waited half an hour or so). Disk Utility pops back up again. i click reinstall OS. it doesn't show an option on which drive i'm supposed to reinstall the OS to. Uh-oh. I looked at "erase", it senses the drive. it's there. i can verify and repair it under erase, but when i try reinstalling a new copy of the OS, no SSD option shows up (where i can install the OS).

WHAT WORKED FOR ME:

I found that my problem was that I did not give a name to my SSD when I erased it the first time. i erased the SSD again (when the internet recovery was finished, but THIS TIME, i made sure to write a name for the SSD i was erasing. when i started the reinstall option again after erasing was finished, my SSD showed up as an option.

Solution 2:

Yes - internet recovery fails to see an internal drive (or external drive), it's almost always time to swap hardware / repair things.

You could on some rare instance need one last SMC / NVRAM reset and try again on a different network internet recovery if you think the checksum / validation that the boot image is correct was somehow failing at the same time as the download failed, but this almost always is a hardware service needed situation.
