Q: my SSD internal drive disappears after an upgrade
Hi,
my mac mini i5 2.5 GHz is having a very strange behavior after an upgrade.
ok, in the beginning It had Yosemite when I bought it, i upgraded to El capitan just by curiosity and put 16 GB RAM. In fact I work on two other (2.1) mac mini:1.83 and 2 GHz. Every thing was fine. So I made an upgrade myself with SSD ADATA SP550 480 GB and 1T B as a second drive. I had difficulties to finish the technical mounting of the machine. So I left for few months. Well, I had to wait for a new ribbon cable from china, the first one was damaged.
Also, I couldn't close the mac mini some screws didn't fit. After a final retry my system didn't mount, well I had the Apple and the normal routine and even a desk, but couldn't access to any thing, no mouse, no keyboard. So I decided to boot on apple's Network, I installed mountain lion, hoping I can get back my SSD with El capitan, but none.
I first bgot on my desk the second internal drive which shows 1.45 TB instead of 1T.
My SSD was recognize by the system in the system info, I have the captures of it. But never mount, TechTools have analyze it , and it seems in good condition, but never mounts. Even Diskwarrior saw it ! as a hardware.
I made all the upgrades for mountain lion 10.8.5.
I decided to open the mac mini again detached the SSD and put it back, closed the mac mini with two screws missing.
Now the SSD had disappeared from all system, Techtools, Diskwarrior, DiskTools quits every time now.
I was trying to install El capitan from app store, but iterrupted the operation, I think If I did, I will lose my mountain lion
So how do I install El capitan without losing my Mountain Lion, my hope is to get El capitan to communicate with another capitan and recover my SSD with all data. I couldn't access to it with 10.7.5 on the other mac mini.
I wanted to to access to the core i5 as a target but problem of firewire, 400 on the 2.1 and 800 on the i5.
No hardware problem or any of the kind were found by techtools after running few hours last night.
Sorry, it's a long story, but it resumes problems we can face in computing upgrades, cause nothing is really compatible.
thanks for help
