New hard drive adds a couple more years of life to old MacBook pro

Mein Problem

Computer slow. Reinstall of OS failed on existing hard drive

Meine Reparatur

Very easy. Pictures on ifixit site were very clear!

Mein Rat

Hardest part is creating USB drive with Mac OS copy. Need this to boot up computer once new hard drive us in machine and to install OS. Ifixit had no good instructions for this.
