Hi, I have a 2012 13" MBP and just recently, I ran into a serious problem of the OS crashing then it would not restart (just have the spinning wheel with the Apple sign). I tried various ways to fix the problem, but the disk utility would not be able to verify nor repair the disk. I even saw forum posts that suggested going into single-user mode to solve the issue but that would not work either. In the end, I just decided to delete the entire partition and start-over by creating a new ML install. This was such a headache and by pure luck I was able to at least use Target Disk Mode with another MBP to pull off the files I needed. My question is: should I be worried that my harddrive is no longer stable? I would hate for this to happen again, but once I deleted the partition and verified the drive, it said it looks OK. I'm not really sure why this is happening, as the computer is only a year old and I use it mostly for word processing and data entry. It is a 500 GB drive and I was using maybe a third of that with various programs and music and such. Any insight or suggestions you could provide would be great.
