My MacBook Pro (see sig for specs) has been very sluggish since yesterday. When it first froze yesterday (around 9:00 AM), I just shrugged it off, and rebooted. It didn't freeze again until this afternoon (around 4:00 PM). It just froze again a few minutes ago. This hard drive is not an original part. It is the bare drive that I grabbed from an external drive (was purchased just for this purpose, was not used until was put in my MBP). I have used the drive around 8-12 hours per day since late April, early May. I have been yearning for a seagate Momentus XT, and I am thinking that this may be the time to buy. But before I buy, I am looking for someone to tell me if my drive is failing. Also, my parents likely will not let me get a new hard drive for about a month or so. But if/when my drive is actually dead/dies, they will likely allow me to order a Momentus XT. Also, I have a backup of my hard drive, so I am not worried about data loss.
