    I keep getting this warning. I use a 1TB Seagate external hard drive. Problem ejecting drive.PNG
    It occasionally ejects just fine, but mostly it keeps giving me this warning, even after I've long closed out all other programs.
    I use a custom built computer with an EVGA GTX 960 graphics card, an Intel Quad-Core i7 CPU, with a Samsung EVO SSD.

    Download WinObj and Procexp from sysinternals WinObj and Process Explorer
    • Open Winobj with "Run As Administrator" and expand Device and locate your USB drive. If you only have one internal drive it will be Harddisk1.
    • Right click on it and select Properties.
    • Under the Details tab, References if Handles is greater than 0 then a process has something on the device open
    • Now Open procexp with "Run As Administrator"
    • Click on Find at the top and type in the disk name and click search for this example Harddisk1
    • Select the process and it will highlight the process and the handle in question
    • In the lower pane of procexp you can right click the handle and close it (please note this could corrupt data on the drive)
    • Once the handle is closed you can safely eject the drive.
