Windows: Everyone who's ever used a USB drive knows the horror of looking for it when you need it only to realise that you left it behind plugged into the last computer you used. With USB Alert, you'll get a warning when you shut down to unplug your USB drive before you go.
USB Alert will play a warning sound and display an on-screen alert every time you issue a shutdown or lock command warning you that you have a USB storage device still connected to the system. From there you can see your connected devices or dismiss the alert – but the warning makes all the difference.
You can always attach your USB drives to your keychain in the hope you won't forget those, but if you're the forgetful type, you might just leave your keys behind with the drive. Better yet, you could just use Dropbox and forgo USB storage devices entirely. How do you make sure you don't leave your drives behind when it's time to leave the office for the day?
