MacBook Pro 13" Unibody Early 2011 Optical Drive
iFixit is a lifesaver again. I consider the physical swapping of the hard drive to have been very easy actually. The only thing I had to do different was to use Carbon Copy Cloner instead of SuperDuper! to clone my old hard drive. I had been getting warnings about my hard drive from Tech Tool Pro so I decided to replace it before it failed altogether. I tried twice to clone the drive with SuperDuper! only to have the process fail in the end after running 6 hours. Because my hard drive had some bad sectors and one bad file, SuperDuper would not complete the cloning. Carbon Copy Cloner however easily identified the bad file, showed where it was located, allowed me to delete it and completed making a bootable hard drive. The deleted file could be restored later from a Time Machine backup.
Be sure the three plastic tabs on the bottom of the black front cover are inserted fully when you snap the cover back into place or else you will get a message saying the ink door is not closed.
I skipped the step about disconnecting the speaker cable. No problem.
I removed the battery cable for the repair. When I plugged in the MagSafe adapter after the repair, the Mac turned on automatically without pressing the power button and I was a bit worried, but after a restart everything worked fine again. I did have to reset date and time in Preferences. The battery was recognized OK.
