Problems with SSD and HD
Hi, I am having problems since long time ago when I am working with my SSD and HD together. This is my history. I hope I can fix this problems finally with your help. Thanks in advance.
MacBook Pro 9.2 (13", mid 2012)
2,9 GHz Intel Core i7
8 GB 1600 MHz DDR3
Boot ROM: MBP91.00D3.B0C
Two years ago I remove my super drive and I installed a Crucial M4 128Gb where I installed the system and apps and I kept the genuine 750Gb HD in the main bay for my data.
I don't remember when I started with my problem, continuous freezing beach balls, but I started with them when I had Mountain Lion. At first I thought it would be a software issue so I did it format and I installed Yosemite but the problems appeared again the first day. I have good days with maybe 4 or 5 freezing during 20 secs or bad days with freezing each 10 minutes. Apple Hardware Test said everything was ok.
I started to think the problem was the SSD.
15 days ago I bought a new SSD, a Samsung 850 EVO (500Gb) and the things got messy.
I removed the Crucial SSD and I installed the HD in its place (Optical Bay). I installed El Capitan and the apps in the SSD (Main bay) and I set my data in the HD.
Before I bought the new SSD, I had the Crucial SSD in the optical bay and the HD in the main bay. When I installed the Samsung SSD, I switched them the bay.
By the way, I think the genuine 750Gb HD is Sata II (3Gb/s) but I am not entirely sure.
During two days everything was working perfectly. Then I shut down it and after two hours, when I turn it on the problems appeared again but this time worst.
Freezing beach balls all the time with every click. I couldn't do anything.
I was trying it with no success. One day after I started to get this errors when I tried to load the system.
Sometimes I achieved to get the logging screen but weird things happened. My user disappeared and I only could log in with the guest account.
I got this Kernel Panic too. There are 3 images but it's the same kernel panic.
Three days ago, I removed the HD of the optical bay and I left only the SSD in the main bay. I reinstall El Capitan again and since then all is working good. No freezing beach balls and nothing.
Now, I think I have to install the HD in the optical bay again and check if still is working good for a few days because I know sometimes is working good during two days and then it crashes and the problem starts again.
I am lost, I don't know the origin of the problem but it's getting me crazy.
I know this post is so long but I wanted to explain since the beginning.
Is this a good question?
