Find which program is blocking USB device when ejecting

Many a time when you try to unplug your USB drive, you get an error message that the drive is in use by some program. It’s a reasonable precaution from Windows. It keeps you warned about a data transfer that might be taking place or any other use. If you unplug during that, it can result in data corruption. However, Windows certainly does not identify which application is using the device so you can close them. In this post, we will share how you can find which program is blocking the USB device when ejecting.

Note: It is also possible that while there is no process accessing USB drive, the lock seems to stay. It generally happens when a program fails to free the lock and Windows see the drive is use.

Dev Eject is a free windows based tool to help you identify the applications which are using and have locked down.

Even though 90% of the time nothing happens but you would never want your USB to become a brick, especially when in an emergency or some important work.
