ssd detected but cannot be used in finder/disk utility
I bought a new SSD drive (Samsung SSD 850 EVO 500GB) last year. I replaced the HD in my MacBook by this SSD and I replaced the CD-drive by the HD. So I have one SSD and one HD in my mac. I formatted everything, I chose the SSD as my main drive and everything was working well... until my laptop froze last week and shut down. When I turned it on, I couldn't do anything (stuck on the first page when you have the apple logo and it's loading). So I used the recovery mode and used my HD as boot disk. I had a look at Disk Utility and I could see my SSD but it's in gray... So I cannot access it or repair anything. The data is still in it because I scanned it with a software and all my files are on it... I tried to repair permissions but I still cannot access it.
It's weird because it feels like my laptop detects the SSD but cannot use it
Is this a good question?
