One of my coworkers told me that he fried his hard drive, and had to take it to apple to get it fixed. He said that it was cause his Safari page and other apps would take real long to load. Anyway, I've been noticing that my computer has been slow lately also. He said that it's from my hard drive. I told him that I turn my computer off and on everyday. And he said that you never turn off a computer (or a tv either). He said that when a computer is turned off, and once you turn it on, a huge power surges to the computer to turn it on, and doing that continuously will affect the hard drive in the long run and it will kill it. He thinks that my hard drive is dying (cause its been running slow, and cause I turn my computer on and off everyday). So, my question is: Do you guys turn off your computer every night, or do you just have it asleep the entire time? I mean, the entire time!?
