SSD Drive Readable, but Not Writable, Not Booting as Startup
I want to add an internal SSD drive as my startup disk in the Optical drive location in my Macbook Pro 15" late 2011. However, after successfully rebooting from the SSD Drive externally, it froze up after about 10 minutes.
Here's the scenario:
1. I connected a new Samsung SSD 850 EVO externally via USB adapter.
2. I formatted it (“Mac OS Extended (Journaled)” with a single GUID partition) and ran SuperDuper to completion.
3. I rebooted holding "Option" and selected the new SSD drive.
4. It worked, and I could open programs. MS Office just needed license key.
5. A DropBox login window appeared and I logged in. It said not enough space available on drive. It asked "Sync Selected Files" or "Sync All Files". I didn't want either, so I just closed the window, but it appeared to start syncing all files anyway.
6. At that point, the fans started spinning rapidly, and after about 5 minutes a transparent gray screen came down and said "Restart your computer by holding down the power button"
7. I restarted using the HDD Drive. A message popped up that said the SSD drive was readable, but not writable, and that I should reformat the drive. "Mac OS X can’t repair the disk “Samsung 500GB.”
8. To test again, I restarted holding down "Option." The SDD drive was still available. I selected it, but the computer went black and shut down.
9. I restarted normally from the HDD drive without any problem, but received the same message regarding the SSD.
Scenario questions I have before I move forward:
a) Is the drive okay, and just needs to be installed internally at this point?
b) Is the drive okay, but needs to go through erasing/formatting/superduper process again?
c) Is the drive fried?
d) Did this happen because too many things were going on through the USB connection, and syncing with Dropbox caused it to choke?
I assume I will need to erase/reformat/copy all over again, but I'm hoping someone can tell me that's not the case. I'm going to get a beer while I wait for word from on-high.
Is this a good question?
