I have a dell XPS 17 (L701X). When it runs on battery the hard drive ticks loudly. I've gone through all the power options to make sure there are no differences between the battery profile and the plugged in profile. Any suggestions?
Thanks! I thought that too. It's a brand new drive. I'm on my 2nd Western Digital Scorpio Black wd5000bpkt since January 2011 when I got the laptop. Dell wouldn't replace the original drive that was having the exact same behaviour since the drive wasn't completely dead yet so I just bought a new drive and replaced it myself since my data is worth a lot and couldn't afford to have a down day with my laptop while I rebuilt it from a dead drive.
Would you have any clue why the drive only ticks when running on battery? Could the laptop HD controller or laptop voltage/current regulators from the power supply be killing the hard drives?
