Hard Drive Failure.
Today I found out one of my media center hard drives decided to die. My media center has been acting strange all week but today was the first evening I was actually able to investigate the problem.
After pulling off the side of my case to first figure out what the popping noise was I heard late Monday evening, I really didn't see anything unusual. I then proceeded to investigate the hard drives since two of them disappeared off my computers radar. Upon investigating and through many tests, I discovered my secondary slave drive (a 120 GB Hitachi Deskstar 7200 RPM P/N 07N9549) died. This sucked! I had a dozen DVDs on that drive in ISO format so I could just quickly play any of them without putting in an actual DVD Disc.
So without any doubt I will be looking for a hard drive to replace my dead one plus a few new fans, as some of them are getting really loud and are annoying the crap out of me.
