I'd bought an SSD that I'd put in my early 2011 13" MBP to make a DIY Fusion Drive in conjunction with the original 500GB HDD. A few weeks ago, I enabled TRIM (using TRIM Enabler). 5 days later, the SSD totally died. Now, I know correlation doesn't imply causation, but could enabling TRIM be what broke the SSD so much so that even a total reformat (which I've attempted to no avail) couldn't fix it? And if so, how do I un-TRIM it?
For those of you who don't want to look at the link to my past question, basically my SSD was working fine until one day my computer became unbearably slow and then hung every time I tried to reinstall OS X 10.10.1. Disk Utility said the disks were okay, but the install would never work. My computer's working fine now because I'm running entirely on the HDD.
