I recently installed a dual-drive setup where I have an SSD and an HDD. I had installed the OS and Apps on the SSD, and other stuff stayed on HDD. Recently my battery died, and I have been using the laptop on power (taken the battery off) because of which it would experience sudden shut down (due to frequent power failure in my area)
Yesterday when I started the Mac, it loaded up a grey boot screen with a loading bar. The loading bar took about 10-15 minutes to complete and then the Mac shut down again. I restarted and same thing happened.
I then booted in Recovery Mode, and found out that the SSD Disk is showing up fine (Verified). However, the partition on it is greyed out and the Disk Utility can't seem to repair it.
I want to know what I should do now (will most likely re-install OS X), and if the problem is with the SSD or is it just that something went corrupt (at the OS level) on the partition?
OS X Mountain Lion, SSD: 128 GB Samsung Evo, MacBook Pro 13" Early 2011 Model
