    I am so pleased to have a great solution for my top issue today. i was wondering if i could recover my most important data from USB. I searched the solution from net. Then I found this page which filled me with happiness as I finally recovered my date following the instruction of doing what if your USB access denied

    This is outdated information for the early Windows 10 with the old Control Panel. You can still access the old Control Panel, but if you uncheck the Hide protected operating system files option, the later Windows 10 update will still show the "C:System Restore Information folder is not accessible" error popup when you search in File Explorer. The System Restore information is not visible anywhere. Windows 10 has blocked access.

    Local Disk now has a different name, usually the name of your brand of computer.

    Thanks for info
    Crazy though that MS made it necessary for users to go through these hoops just to view the results of a chkdsk operation!

    Worked..kinda. Unlocked all drives in the network, but the root. Not all directories within the folder were unlocked.

    Re-locking worked on half. Ran for individual drives and all but one were locked.

    The one that could not be re-locked was a WD Passport Ultra 4TB external drive.
    All drives were on hubs which were, in turn, plugged into a laptop dock.

    Worked for me. There was a really old backup folder from 2012 hidden behind that "no access" wall. Thankfully I did not follow the advice from another article to "delete all libraries" – that would have been disastrous.

    Worked for me! I needed to delete an identical IndexerVolumeGUID file that is created when I do a Macrium image of a disk. Windows can't deal with two disks that have the same values in that file. Deleting that file from the clone allows Windows to create a proper file upon reboot. Your process allowed me to access that file in the System Volume Information folder of the clone. Many thanks!

    FIGURED IT OUT! You MUST go to the UI,
    For Win7:
    1. Right-click "Computer", choose "Properties,"
    2. Then click "Advanced System Settings," choose "System Protection" tab
    3. CHOOSE THE DRIVE IN QUESTION (in my case "F:" drive; a non-OS external)
    Note: Make sure the radio button is selected for "Turn off system protection." IF it happens to be turned on, you may need to turn off, then reboot, and com backe to this point
    4. From that "Configure" page, next to "Delete all restore points." click "Delete"
    5. Answer "Yes" if it prompts you with "Dude, are you sure? This removes those thingys!"
    * It should come back with message "All restore points deleted."
    That's it. Now go look under 'System Volume Information' folder; and those SID files gone! And now, from command prompt,
    1. Change to F: drive (change to the drive in question) cd /d F:\
    2. Remove the system volume information folder: rmdir "system volume information" /S
    3. Answer yes to "Are you sure?"

    Did NOT work. Even in your above example, it shows "Access Denied" to very specific 'sid-based' folder(s) under the "System Volume Information" folder. AND, to be clear, I am using an alternate drive – i.e. "F:" – non-OS drive; just trying to clean it up without formatting. And I get the same issue. Not even from command line and/or ICACLS will it let me grant access to those files (six files in my case).
    So, why on earth, for a NON-OS drive, even AFTER I remove system+hidden attributes; does it fail to allow me to take ownership & delete these files? I am guessing maybe it is automatically setting this drive for "system protection" somehow; i.e., keeping these files locked maybe??? If so, that would be something I can "undo" somehow.

    This worked! I can now create a system restore. This was a lengthy but easy to follow process. Thank you very much.
