Q. Windows Explorer in Windows XP SP2 does not display the correct volume information for a removable media device that is changed when the system is in standby or hibernation mode?

When you insert media into a removable media device, like a USB 2.0 card reader, attached to Windows XP SP2 (Service Pack 2), and place the computer into a low power state, like standby mode, or hibernation, replacing the removable media and waking the computer results in Windows Explorer not displaying the new media volume information, even though the device works correctly.

This behavior occurs by design, because no notification of media change is sent when the computer is in a low power state.

To avoid this problem, DO NOT replace removable media when the computer is in a low power state.
