Hi all. Today I bought a new ssd-shnik "wd-blue 250 gb" but my Mac refuses to see him, not as an external drive (shows a message that this disk cannot be read on the computer) or when the ssd to put in place the hdd and try to restore using the Internet (just no volume to install), or if start the mac with the stick (putting a ssd in place of hdd) installer new Sierra, nifiga not see it and that's it. Disk utility is powerless. But the hdd tills great, no complaints there, so most likely it's not in the loop. What should I do mates???
ps. Make a screenshot of "system information" obviously, the mother sees this ssd, but nothing to do with him can not.
