    Problem Ejecting Sandisk Flash Drive

    Whenever i try to eject my Sandisk flash drive, by right-clicking on it's icon and clicking on "Eject Cruzer",
    I get an error window with the title, "Problem Ejecting USB Mass Storage Device".
    The message says, "Windows is unable to stop the device 'USB Mass Storage Device'.
    Don't remove this device while it is still in use. Close any programs using this device and then remove it."

    This only happens the first time I attempt to eject my flash drive since connecting it.
    The second time I try to eject it, it always works.

    Does anyone have any idea what the problem could be?
    I know it's not a problem with my flash drive, because it works just fine on other computers.

    I tried uninstalling and reinstalling the driver for the flash drive in the Device Manager, but that didn't work.

    Hi retroboy87,

    I don't why that's occurring, but just so you know, you should be able to configure the flash drives so they are safe to just pull out, rather than "safely removing them." I know this is not an answer, but more of a 'work-around' if needed. It should already be defaulted that way as well. More HERE.

    The safely remove is there to make sure that all write buffers have been written. That is normally the case if you give it a couple of seconds. The 'false' busy signals can be ignored at that time.

    Thanks for the replies.

    I already have Quick Removal enabled.
    I know I can just pull my flash drive out without safely removing it, but I want figure out what's causing this problem.
    I'm fine with using Quick Removal in the mean time though.

    Is any program using it?
    I mean is it music that a media player is pointed to, is it being used to back up data?
    Is it mounted in File Explorer?
    You can also try running chkdsk in case it was pulled once when writing wasn't finished.
