How are you? I have an external HDD Transcend:
In this last one, I have the WD10SPZX HDD 1To SATA 6Gb. I extract this hard drive from this pocket and put it in my MacBook Pro 13 mid-2010. But the system of my MacBook Pro 13 does not recognize him. I format this HDD to macOS extended journalized.
Where is the issue to fix for this WD10SPZX HDD 1To SATA 6Gb?
