My hard drive stopped responding, I formatted, tried to install new OS but I could not boot my MacBook Pro. And also it had run out of space so it was time for a new hard drive.
Ordered my new hybrid hard drive from ifixit, arrived within two days on international shipping and it took fairly little effort using the step by step guide from ifixit and the youtube video available for repair guides. Within 15 minutes, i was ready to reinstall my OS.
Excellent resource for repairs. Keep up the good work.
