Internal hard drive disk not recognized
My internal hard drive disk has stopped working on my Macbook.
The hard drive is not recognized at boot up, so I get the famous question mark. I tried to connect another hard disk and got the same error message. So I guess the problem comes from the logic board?
When I try to access it from the external bootable drive using Disk Utility I can't see it either.
The disk I'm using is good, and it works when connected with USB (this is what I'm running now). But of course I would prefer to put it inside and connect it with SATA.
Now, I'm wondering what I should do. A new logical board is expensive, and it would be too bad to change it completely, because everything else is working perfectly. So, I'd like to get some advice, maybe for how to check the connectors, change the disk controller or add a new one, or whatever can help to get a more practical solution.
Thank you for your help.
