When the hard drive is connected via USB/SATA patch cable, the drive works great and is fairly quick and reliable. When I take the same drive and swap out my older internal MacBook hard drive, the startup would hang on the spinning disc. Other times it booted up just fine. Other times, the Apple symbol would come up, but no login screen. The drive was formatted using Apple's Disc Utility as directed in the Hard Drive directions. Tried HFS+, Mac OS Extended, etc.. I restored the Hard Drive using Time Machine. Sometimes the computer would boot up, other times it wouldn't. Reformatted the drive again, used a clean disc image of my Hard Drive. Same boot problems. Last attempt, I did a low-level format, reformatted using Mac OS Extended, and a completely clean install of the OS. Same results. I have put my old drive back in and have had no problems other than lack of free space. This is probably a good hard drive, but I think it is incompatible with older MacBooks. Mine is a Late 2008 model. Newer models with different hardware may have different results.
