USB storage device: The USB device might not display if it was stopped previously and not disconnected from the USB port.
To resolve this issue, disconnect the device, wait approximately 20 seconds, then reconnect the device to cause the device to display in the Safely Remove Hardware window.
If the device still does not display in the Safely Remove Hardware window, then restart the computer, and repeat this process.
Memory card in a USB card reader: If the device is a memory card in a USB card reader, restarting the computer should correct the problem.
Do not use the Safely Remove Hardware icon to remove a memory card. To remove a memory card, use Windows to eject the card by following these steps:
Insert a memory card when the light on the reader is not flashing.
An Autoplay window displays. If it does not display, open the card using Window Explorer.
The memory card has a drive letter associated with it, just like a floppy drive, CD-ROM drive, or hard drive. Use the memory card as you would use any other drive on the computer. For example, double-click the memory card icon to open a new window showing the files on the CompactFlash card.
When you have finished working with the files on a memory card, right-click the memory card icon and select Eject.

Wait for the light on the memory card reader to turn off or stop flashing.
Remove the memory card from its slot.
