Shortly after installing a new SSD (Samsung 830) in my Mac Pro I started getting an error saying the the disk had been ejected wrongly. The error appears randomly and doesn't say which disk it is but I assume it's the SSD because apps on it become unresponsive. When the error appears, most apps freeze but not all, which is weird because if the SSD was truly ejected then I assume nothing would work (have OSX installed on the SSD). Every now and then Finder will show an error saying it is unresponsive on start up without the SSD error occurring. I have tried to repair permissions and verifying the disk. It has the latest firmware installed. Should I return the SSD for a replacement or is it possible that something went wrong when cloning OS X from my old SSD to this one? Thanks for your help!
