I scavenged a hard drive for my currently lifeless 2009 Macbook Pro 13. The scavenged drive (from a 2010 white Macbook) had been working because it was taken to an electronics store to have its data transferred to a new computer.
I installed the drive, turned on the machine and got the question folder. Maybe they just stripped the drive of all of its data or perhaps the drive has failed. Is there a way for me to find out without spending too much money?
