Short answer: Probably not.

Pull a USB flash drive out of your Mac without first clicking to eject it, and you’ll get a stern, shameful warning: “Disk Not Ejected Properly.”Probably not. Just wait for it to finish copying your data, give it a few seconds, then yank. To be on the cautious side, be more conservative with external hard drives, especially the old ones that actually spin.

It’s worth taking a look at what’s happening behind the scenes when you remove a thumb drive, and why it’s unlikely to mess up much, if anything.Say you’re copying a file from your computer to a USB drive. Your machine may actually be using something called a write cache; instead of transfering the file from one device to the other directly, it’s using that cache to make the process more efficient. The cache is just local memory storage that your computer is really good at writing to, quickly.

Managing data in the write cache is where the “eject” feature comes in. “The eject basically says, ‘okay, we’re pulling this thing out, flush the write cache,’” Pavlo says. The first possibility is that the file you were copying to the USB drive gets corrupted . After that, there’s the chance that another file on that thumb drive gets corrupted, too.

“The catastrophic form of failure,” he says, “would be that if you picked just exactly the right time when it was in the middle of a write, so it had written some bits and not others, you could corrupt your USB drive—but your chance of doing that is so slight, that I have never had it happen, [and] never heard of it happening.
