The hard drive on my computer stopped booting up. Apple MacBook Pro 2.66 GHz Intel Core 2 Duo with 8 GB 1067 MHz DDR3 with 500GB Hard drive (spinning type) MacBookPro5,3 OS X 10.11.2 I cannot think of anything that might have caused it to suddenly stop. My suspicion is the drive needs to be replaced. I have two question. Based on the following steps, do you think it is dead? When I turn it on it usually shows the circle with slash though it, and then eventually it shows the OS X Utilities menu with the four options. 1 Restore From Time Machine Backup When I choose this option, my Time Machine Backup partition of my external hard drive cannot be located, even though it can find another partition on the external drive. 2. Reinstall OS X The internal disk and attached external disks are not options I am shown as available to reinstall OS X. 3. Get Help Online 4. Disk Utility When I choose this option, the disks and partition are grayed out. I was able to try to do first aid on the internal disk once and the attached image shows the results. I tried an OS X Recovery In this case disk recovery gives only one option for OS X Capitan installation and it is the Recovery HD (650MB total, 121.9 available) I also tried resetting the System Management Controller (SMC) The result was I was again show the OS X Utilities screen with the four options https://support.apple.com/en-ca/HT201295 Assuming it is dead, would the Western Digital WD500LPCX 500GB Blue 7mm, SATA 6 GB/S 16 MB I purchased be a suitable replacement?
