Windows 10: Can't safely remove Seagate Expansion drive connected using USB3.0SS

    Can't safely remove Seagate Expansion drive connected using USB3.0SS

    I've got a Seagate Expansion drive connected to my PC using a USB A - USB 3.0 micro B cable.
    I'm unable to find any "Safely remove" option, and at one point when unsafely removing I got a blue screen.
    I've tried:

    • The tray. Nothing there.
    • Running "rundll32 shell32.dll,Control_RunDLL hotplug.dll", and the drive does not show up there.
    • Looking in device manager. There it shows under "Disk drives" as "Seagate Expansion SCSI Disk Device" and I see that under "Storage controllers" I've got a "USB Attached SCSI (UAS) Mass Storage Device".
    • If I on the device go right click, "Properties", "Hardware", select it, "Properties", "Policies" it has no "Removal policy" options. Only "Write-caching policy" options.

    How do I make Windows understand/handle this drive as an external drive that can be safely removed?

    Are your USB Chipset drivers up to date?

    There's a Seagate KB on the topic. Does it help?

    Windows will not allow me to safely remove my drive. It keeps reporting the drive is busy or in use

    /* EDIT */
    What is your actual Seagate model? Some drives are configured as non-removable by the vendor

    Better yet here's how to check for yourself if your device tells Windows if it's removable. Download USBTreeView. Select your drive and check capabilities and status in the Device Descriptor.

    So I've been testing this for a while now, and I got it working on several other computers.
    Somehow it seems to have something to do with a specific set of USB 3.0 ports on the back of my computer. The one I was using didn't give me a "Safely remove" option, but when testing some of the others the option appeared.
