Windows is full of cryptic error messages, but few are more annoying than seeing a warning every time you plug in a USB drive. You know the one I'm talking about: "There's a problem with this drive. Scan the drive now and fix it."
So you go through the motions, scan the stupid drive, fix it, and everything's fine. Then the next time you connect it to your PC, there's that darn message again.
So how do you fix this problem for good? Here are a few tips.
A common reason for seeing the scan and fix error message is that your drive needs to be ejected from the system before yanking it out. Most of the time when you just yank a thumb drive out of a USB port nothing bad will come of it, since Windows allows you to do this by default. But there are some cases where Windows wants you to properly eject a USB drive from the system.
There are two standard ways to properly remove a thumb drive on Windows and you probably know both of them. Just to review, however, the easiest thing to do on Windows 8.1 is to click on the upward facing arrow in the lower-right corner of your taskbar. Then look for the USB icon with the green check mark, right-click it, and choose the drive you want to eject from the list of USB-connected drives.
Next, wait for a "Safe to Remove Hardware" balloon to pop up from the taskbar and then pull out the USB drive.
Do that every time and the scan now message should stop appearing — after you allow Windows to scan and fix the drive one last time, that is.
Watch out for multiple OS set-ups
Ejecting drives properly goes for any other operating system you plug the drive into. For example, I often shuttle a USB drive between a Windows PC and a Linux-based Raspberry Pi hooked up to my TV in the living room. If I pull the USB drive out of the Raspberry Pi before ejecting it properly, Windows will also scream at me and ask to fix the drive even though the improper ejection occurred on a Linux-based system.
If you can't be bothered with going through the motions to properly remove a USB drive, another option is to make sure write caching is disabled for the drive, though we don't recommend doing it if you're handling critical data.
Write caching is a feature that allows Windows to collect (cache) a bunch of write commands in memory and then save all the data to your USB drive in one big batch. Windows enables this option by default, as it protects against potential data loss in the event of a sudden power failure.
