Hard drive or SATA connector fault?
A few days ago I received the dreaded stop sign on boot screen, fearing my hard drive has finally failed I quickly purchased a compatible one. The next day my original hard drive was 'working' again, slowly but steadily it came back to life. As my new hard drive had arrived I decided it was time for an upgrade anyway. I created a bootable usb and with my new hard drive (seagate 1tb sshb) connected internally I was ready to breath new life into my old mac. As I was formatting the seagate to OSX journaled and GUID I kept getting mounting errors and disk errors. After several attempts I decided to give up. I then connected the seagate through a SATA to usb cable (externally) and voila! it was able to format to OS X journaled with a GUID map (does this mean the drive is fine?). So i connected the seagate internally and ran the boot drive again. Everything was successful up until the very last moment 😟, where i received the dreaded
"OSX could not be installed on your computer file system verify or repair failed. quit the installer or restart your computer and try again"
So I tried it again and the results were the same.
Whats going on? Is there a problem with the seagate or is there an internal problem with the connections?
Both are pretty easy to fix as parts are readily available, or could it be something else?
Ask if you need more details, I feel this is a pretty general problem.
Forgot to take photos of any error screens as well
Thanks
