Problem Ejecting USB Mass Storage Device "This device is currently in use. Close any programs or windows that might be using the device, and then try again."

Original title:Problem Ejecting USB Mass Storage Device

When I try to safely eject my external hard drive safely I get an error message with this title telling me that "This device is currently in use. Close any programs or windows that might be using the device, and then try again." I have done this. I have also tried closing every program running on the computer and it does not help. I have also tried restarting the computer and this also does nothing. If anyone has any ideas that would be helpful please let me know.

Hi A. Cook,

1)       How long have you been facing this issue?

2)       Is this issue confined to any specific USB device?

This behavior can occur if there are open handles with any files in the USB (Universal Serial Bus) Mass Storage Device are in use by another program.

 
Method 1:

a)       Download Process Explorer from the link below

b)       Click Find, Find Handle or DLL (Dynamic Link Library) in the tool menu.

c)       Type the drive letter of the USB device in the Handle or DLL substring textbox, and press Search Button.

d)       Find the process and its PID (Process Identifier) in the following box.

e)       In system process tree view, find the process according to the Find Handle or DLL dialog box.

f)        Press Ctrl + H to show Handles in Lower Pane View.

g)       Find the File according with the drive letter, and right click it, choose Close Handle.
