Hello, I just got a new MacBook Pro a few weeks ago. I dropped it about a foot onto the hardwood floor, and it was dented slightly (very very slightly, it is really not that visible). When I dropped it, it was shut down so nothing was on. Also, my computer has been running perfectly normal since then. I did at SMART scan and noticed that there were 72 reallocated sectors. I read that these are not threats, but threats that have been redirected. Basically, my questions are: how many reallocated sectors are acceptable, should I replace my hard drive, and if my hard drive is dying, how long does it have left until it goes? Thanks!
