The hard drive in my friend's laptop, a mid-2012 Macbook Pro, was on the verge of completely dying. We swapped it out with a WD5000LPLX that we found on Amazon. Everything seemed good, but the Macbook seems to completely ignore the existence of this new hard drive. It doesn't show up in the boot menu, and it isn't visible at all when trying to do an Internet Recovery of OSX. Nothing.
However, when plugged into my desktop pc, it functions perfectly fine. I had to initialize it from the disk manager and format it first, but I had no problems copying files to and from the disk. Plugging the hard drive back into the Macbook formatted as either NTFS or exFAT is of no use. The laptop simply does not see the hard drive and there is no way to format it OSX Journaled or install OSX.
We also tested the old drive again, and we were able to get into the operating system... so its not that the SATA cable was broken or something.
Is it possible that the new drive, since it is 7200rpm vs. the Macbook's original 5400rpm drive, is incompatible for some reason? Or maybe some other reason I don't know about.
Any thoughts?
