    Trying to figure out what Windows is doing with an external hard drive

    It's hooked in right now until I organize and transfer over archive stuff, and there's a light on it, and it'll just randomly start blinking, and I can hear the hard drive arm activating or resting (locking?), even though File Explorer is not open and I'm doing nothing related to the drive. Right now it's constantly blinking and has been for several minutes.

    I'm not seeing how to see what Windows or whatever is doing with the drive...

    If that drive is making a clicking sound when you see activity it usually means it's failing or has failed. That activity is from the Voice Coil Relay trying to move the arms across the disk then snapping back to rest hence the click. I'd replace it as also possible the interface in the case that controls the drive may be the issue.

    Many operations can be running on the background. Scanning for Virus or defragmenting are some of them.

    I agree with Megahertz. Defender quietly scans all external drives.

    It is possible that it is the indexing service running.
    My system is quite outdated (v1909) but you can find what is being indexed at Control Panel\Indexing Options, click on "Modify" and then click on "Show all locations".
    In my case I have an external HDD Iomega (I:\).

    Also indexing, which you could turn off for that drive to see if access reduces.
