Four months ago I bought an external SATA case with USB-C compatibility so I can install my iMac OS there, did this because my iMac has built in HDD and was so slowww..
With the case I started using an ADATA 120GB SSD and everything worked like a charm for the past months, up to now...
As an extra fact I have to say 1 day ago I took the computer to another location (car trip) used like 12 hours and take it back to my office (of course I unplugged the SSD and plugged it back a couple of times), this was the first time EVER I unplugged the SSD case.
Today I was working as usual and the computer suddenly turned off and showed a message like this:
So waited for the iMac to restart and continue working, the message appeared 3 times after 20 minutes aprox of working.
The fourth time the message appeared I tried to start up again and the OS didnt started. The apple logo appears up to the loading bar but it turns off at 30% more or less.
This apple logo thing only happens when starting up from the external SSD, if I boot up from the default HDD it works good (I didnt remove the OS from there cause I knew something like this could happen).
So I would like to know what do you thing could go wrong? Maybe the USB-C cable got damaged in the trip yesterday, or its just that the VANTEC case is not supporting this kind of usage, or even the SSD?
I cant use the iMac with the OS running at the HDD, I've get used to SSD speeds both in my iMac and macbook so I would like to solve this problem fast cause iMac is my principal work station.
The drive enclosure is: VANTEC ENCLOSURE
The SSD is (120GB version): ADATA SSD
If I buy a brand new samsung external SSD, can I expect similar issues?
Thank you so much, I would love to hear what you think about all of this!
