I started getting this message on my Acer Aspire laptop (i7 720Qm processor) every time I unplugged it from the power source about 2-3 weeks ago. Prior to that, nothing of the sort happened which bothers me to think that it's not a standard response. Once plugged back in, the disk is detected again and the system automatically requests to run some type of corresponding software installation through user account control. On another forum, this problem was briefly addressed here on page 83 and 84:
This doesn't fully resolve my issue though. I want to make sure there's no abnormallities and get a more firm grasp on what that means so I can tweak it to my liking. Any help is wonderfully and fantasically appreciated after weeks of getting no where with Acer support.
