Windows: To safely remove USB drives and memory cards from Windows, you have to mouse over to the Safely Remove Hardware and Eject Media icon in the taskbar. USB Disk Ejector will do the same thing, but with a quick keyboard shortcut.
USB Disk Ejector is a portable program that runs in the taskbar and lets you set hotkeys to safely eject removable drives. It supports ejection by drive label, drive letter, drive name, and mount point. If you regularly use more than one drive at a time, USB Disk Ejector supports multiple hotkeys, too. Even if you don’t use the hotkeys, USB Disk Ejector’s list of drives is larger than the one built into Windows, so it’s easier to see and eject.
USB Disk Ejector is free, open source software and works on all versions of Windows from XP on up.
