don't know what happen i unable o safety remove my usb or external harddrive... the window pop up a message said " This device is currently in use. close any programs or windows that might be using the device, and then try again. " 

but i has already close all application and this message still pop up



Hi lei_john,


The message (This device is currently in use. Close any programs or windows that might be using the device and then try again) is usually the result of an application, file, open document, music or video file or any other application which is in use (running from the USB flash drive) when you try to remove it by clicking on the Safely Remove Hardware icon in the notification area.


The error can also be caused if your anti-virus is actively monitoring/scanning the USB drive. Normally, when removing a flash drive from a USB port, Windows should stop all the read-write operations on the drive so that it can be safely removed. If not, the flash drive can be damaged or data may be lost or corrupted. However, if Windows determines a file is in use, then it may provide a message which indicates the volume cannot be stopped right now.


So, before ejecting or disconnecting any mass storage device, make sure none of the above activities are performed on the mass storage device before ejecting.


Disconnecting a device


Most USB devices can be removed and unplugged. When unplugging storage devices, such as USB flash drives, make sure that the computer has finished saving any information to the device before removing it. If the device has an activity light, wait for a few seconds after the light has finished flashing before unplugging it.


If you see the Safely Remove Hardware icon  in the notification area on the right side of the taskbar, you can use this as an indication that devices have finished all operations in progress and are ready to be removed. Click the icon and you'll see a list of devices. Click the device that you want to remove. Windows will display a notification telling you it's safe to remove the device.


Hope this helps!
