Interesting facts from Science Alert.
We’ve all been guilty of ripping our USB Drive out of our computers instead of ejecting them properly, only to receive the judgemental pop up telling us we really shouldn’t have done that.
But when everything on the USB works fine next time you plug it in, you can’t help but wonder: does it actually do anything when you safely eject your disk before removing it?
Rachel Z. Arndt explains what that means over at Popular Mechanics:
“For efficiency’s sake, they don’t actually write the files you’re moving to the disk until there are multiple files to move. Ejecting the disk is a way of telling the computer that it’s time to do the writing, regardless of whether the computer deems it efficient. When you remove a flash drive without warning the computer first, it might not have finished writing to the drive.”
This means that pulling your external drive out without warning could result in the file you just saved being lost forever – even if you saved it hours ago.
You can still never be sure exactly when your computer is done with your external flash drive, and that makes pulling it out a big gamble. Bottom line?
“You can remove a disk at any time, but you are at the mercy of how well programs using the disk cope with the sudden disappearance of that disk,” says Remaker.
So go on and continue living life on the edge, ripping those USB drives out with abandon if you really don’t have the 30 seconds to spare.
But just remember what’s at stake next time you’re saving precious information onto your USB drive.
