    Hard drive inaccessible after upgrade - (apps stored on drive run)

    Okay, here's a weird one. And of the searching I've done, it seems others who've had this problem have had encryption, which I don't.

    Problem: When I click on my H: drive or try to access it from the command line, it gives me an access denied error. However, all of the applications that I have installed on that drive run without issue. So, there is some access there. (See attached images. The first shows the hard drive state in diskmanager and in windows explorer. The second image shows the minecrafter launcher profile (that it is stored in H: and the application running, proving that there is some access.

    System: Home built PC: (C:) 240GB SSD for OS, (E:) 1TB HDD for file storage and backup, (H:) 1TB HDD for large applications and video editing files. All drives are Simple, Basic, and none have encryption. All use the SATA connectors.

    I had Windows 7 Home 64 bit with, among many other things, Comodo Internet Security, Virtualbox, ImageDisk.
    During the upgrade process, I noticed that Windows 10, during the upgrade, ran the file system check and fix "problems" on the H: drive.
    (Side note) Having forgotten to uninstall Comodo before the upgrade, I did not have network after the upgrade. The fix was non-trivial as I had to use a second computer to download the unofficial comodo uninstaller. Reboot. Uninstall the network devices. Reboot. And once Windows 10 was up and running, it reinstalled the network devices and the network was available.
    Still, whether before or after the Comodo uninstall and reinstall, the uninstall of ImageDisk, or the uninstall of the Virtualbox network device, I have no access to the H: drive.

    If I have missed any information, please ask and I will try to provide. Are there any suggestions on what I can do to unlock my secondary drive?

    In the second image, you can see that there is a doubled blue arrows on the Minecraft icon. I've read that this means that file or files are compressed. Would this have an effect on my H: drive issue?

    As it turns out, it was a permissions issue. I needed to open the Properties -> Security -> Advanced section, modify the permissions for SYSTEM and Administrators, and add the USERS and Authenticated Users groups.
