There’s a chance that your internal SATA cable is faulty, but there’s no firm evidence yet that that’s the cause of the problem. Does it get past the grey folder with the flashing question mark now? Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. On the right-hand side, select the First Aid tab if it’s not already selected, then press the Verify Disk button if it’s not greyed out if it is greyed out, or if it reports that errors were found, press the Repair Disk button. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”).
Once the OS X Utilities menu appears, select Disk Utility. If you reïnstall your Hitachi HDD, you could try the following steps to see if they would repair it: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Your Mid 2012 MacBook Pro didn’t come with an installation disc, so that’s of no concern. Thanks for reading, it is greatly appreciated!
#SSD FOR MAC PRO 2012 INSTALL#
Also, I do not have with me an install disc 😟 How do I get the new internal SSD working with a fresh install of Mavericks? Do you guys think maybe the connecting cable for the HDD is faulty, not the HDD itself? I really would like to do this myself instead of going to the Apple Store as I am a little tight on money at the moment. This seems as though this is the start-up partition, correct? All of the options to partition and erase the drive are grey and dimmed out. It only has "Disc0" with "Mac OS Base System" right underneath it. I tried using disk utilities from the Internet Recovery option, but the computer won't recognize the new SSD.
I then booted again but this time holding down the Option key. I then took out the hard drive and bought a new internal SSD (Crucial M500 2.5'' SSD with 240GB of storage) and replaced the initial HDD with the SSD, but the folder with the question mark popped up again. After searching through the forums here and elsewhere, it is apparently a faulty/corrupted HDD. After the initial startup sound, a grey folder with a flashing question mark shows up. It froze, so I decided to reboot the machine. So this morning, I plugged in my USB mouse and all of a sudden a grey loading circle came about. 4GB of RAM (never changed it from when I bought it)
