Believe it or not, Laptops do fall. And when they fall the only thing left to do is scream, box and kick yourself in the butt. But apart from just having a damaged laptop, you may just have a damaged storage drive. That damage storage drive may have all the important files you need and you just may have to pull every strand of hair out your head knowing that you don't have your data backed up.
What free fall protection technology does is to protect your internal storage drive from possible damages when your laptop falls. That is what you call a "catching technology"The hard disk is placed in what they call a "safe state" which mitigates against damage and data loss. As soon as that event is not detected by your "free fall data protection drive" the drive returns to normal operation.
