Hi there. I'm trying to help a friend of mine with some hard drive issues on her Macbook Pro. I don't know the year the laptop says, she says she purchased it august 2013, and it's the model which, unlike the current macbooks, has tonnes of i/o including ethernet.
Basically she was using it and when she plugged a flash drive in, it came up with the circle with a line through it symbol which seems to indicate a hard drive error. We rebooted it twice. It will get to the login screen, but goes back to the hard drive error screen after typing in the password and hitting login. *If I go to the guest user that has access to nothing more than Safari, this works and does not display an error*. I've tried booting into recovery (Command+R). Disk Utility shows the actual hard disk along the left normally, but underneath it, the partition she needs to boot from, is grayed out and doesn't seem to be mounted.
When running diskutil mountDisk disk0s2 in terminal, it returns "One or more volume(s) failed to mount". Running "diskutil repairDisk disk0", says it may erase, so I haven't done that for now. Running the First Aid option in Disk Utility on the hard drive returns "Problems were found with the partition map which might prevent booting. Operation successful."
If I go to Choose Startup Disk it shows "Macintosh HD Encrypted Disk", when I press unlock and enter the password it shows "The disk "Macintosh HD" is already unlocked. Use Disk Utility to mount the disk." If I go to the volume in Disk Utility, the mount option is grayed out.
We've got another hard drive I can install. Is there any other course of action before trying this? I've got a mac as well, but it's a macbook air, so no firewire port.
