USB Drives (for Windows systems): If you’re the type who brings their USB flash-memory drive everywhere you go, yet often has to backtrack all the places you’ve been to find it, Flash Drive Reminder is definitely worth the download. The tiny app, and its auto-starting accompanying file, sit on your drive and activate whenever you’ve plugged it into a Windows system. You’ll get a pop-up screen asking you to keep the Reminder app running during your session, and it takes up very little memory. When you go to log off or shut down your session, the reminder pops back up, reminding you to yank out your drive. That’s about it, though there is a “quiet” version that doesn’t present the pop-up window when you first plug in. Flash Drive Reminder is a free download, works on any USB drive (but only activates on Windows systems). If you’ve got a better system for remembering your drive, software or physical, let’s hear it in the comments.
