So I am having a very odd issue with my SSD in my Macbook Pro 13 from 2011. Essentially here is the issue in a nutshell. I installed a Crucial MX100 SSD in my Macbook Pro about 6 months ago. The drive has worked really well for the last 6 months. Yesterday, I turned on my computer and it was taking forever just to start up OSX (Yosemite). I think it took almost 45 minutes to start up OSX. I figured the issue was software related, and I wanted to delete some software off the computer too. So I decided to do a clean install of OSX. When I went into Recovery, I noticed that was slow too, so instead I decided to run it through Internet Recovery. When I went into Internet Recovery, it worked fine until I went into disk utilities. There I noticed the same issue again. When I loaded disk utility, the Apple logo (in disk utility) was almost immediately replaced by a Grey Box and it took forever to load. It was fine clearing everything but if I tried to adjust the partition settings, same issue once again. But once I deleted and recreated the partition it was fine for a bit. Then I tried installing OSX onto the drive, first it wouldn't even pick up the drive. Then I rebooted the machine and it picked up but when it tried to install OSX it said it would take about 1350 - 1440 Hours to install. So I canceled the setup. So now I figured the drive was failing or I had a Hardware issue with the Mac. To rule out issues with the Mac, I put the old 5400 RPM Toshiba OEM Drive back in. It worked fine, I was certain now it was a problem with the drive. I put the drive into my Desktop PC and my it worked with the drive fine. In fact, I took it a step further and installed Windows onto the drive and the drive worked great. No slow down no nothing. I did SMART tests, I zeroed out the drive, I even did a "Garbage Cleanup" of the drive and nothing seemed to help. Every time I put it back into the Macbook I ran into the same issues. But in my PC no issues at all. I have warranty on the drive, but if the drive works fine in PCs I doubt the company I bought it from will replace it. Any ideas what could be the issue?
