So guys, what is your hard drive's power on hours, power on count, and what temperature are they at currently? You can use a tool like CrystalDisk Info to check.
Main Laptop Hard Drive (320GB WD Scorpio Black): Power on Hours: 5748 Hours Power on Count:* 2792 Current Temperature: 49C (I know this is pretty high, I am backing up my computer as I write this.)
Backup Hard Drive (2TB WD Caviar Green): Power on Hours: 946 Hours Power on Count: 38* Current Temperature: 42C (Again, pretty high.)*
