Problem Ejecting USB Mass Storage Device
This to me is the most annoying feature in Windows. Why can't Windows tell me what programs or windows are using the device so I know what to close? Many times, I have tried closing all programs and windows that might be using the device. I even closed programs and windows that I was fairly certain were not using the device just in case they were. In resource monitor, the Disk 1 (E:) Queue Length shows no activity and nothing is listed as using the drive in the Disk tab.Problem Ejecting USB Mass Storage Device said:
I can go into an Elevated Command Prompt and run Diskpart, select the volume associated with the USB Mass Storage Device, and run a remove dismount of the volume, and it still claims the drive is currently in use... How can it be in use if it no longer has a handle and has been dismounted?
I have reason to believe this is either the security software preventing removal of the device, or Windows itself. After some time, I am able to remove the device. This happened to me most recently on a computer with Norton 360 installed, which is supposed to stop all scanning when the system is no longer idle. Windows also was not indexing the drive for faster searches.
Any ideas what causes this behavior? Any suggestions on how to remove the drive if it happens in the future?
