I can't get the Windows File History backup (part of the Control Panel) to work with my USB disk drive. I can't "Turn on" file history. There's quite a lot of background to this, but I don't know what information may be relevant and what isn't.

    Try this end-to-end path for File History with a USB drive:

    1. Verify the USB drive is connected and visible in Windows.
      • File History requires an external drive or a network location.
      • If the drive is not being detected reliably, check Device Manager for device errors. If needed, unplug and reconnect it, or test the disk on another PC to determine whether the issue is the disk itself.
    2. Open Control Panel > System and Security > Save backup copies of your files with File History.
      • If no drive is selected, choose Select drive, pick the USB drive, and select OK.
      • Then select Turn on.
    3. If File History says the drive was disconnected or asks to reconnect it:
      • Make sure the USB drive is physically connected.
      • In Control Panel > System and Security > File History, reselect the drive.
      • After reconnecting, wait for the next scheduled backup, or select Run now to start one manually.
    4. If File History still will not turn on, check for a conflict with the older Windows Backup schedule.
      • File History does not allow itself to be turned on if an active Backup and Restore schedule exists.
    5. If this started after the September 2026 Windows updates and the USB drive is connected but File History still shows a reconnect message or the Turn on button does nothing:
      • This is a known issue affecting File History.
      • Install the latest Windows update. Microsoft states the issue is resolved in updates released on and after September 22, 2026, such as KB5124010.
    6. If the USB drive appears but still behaves inconsistently, test basic hardware detection:
      • In Device Manager, look for warning icons on the USB or disk device.
      • A common recovery step is to right-click the problematic device, select Uninstall device, then select Action > Scan for hardware changes.
      • Caution: this changes device detection state and should only be used if the drive is not being recognized correctly.

    File History backs up personal files such as Documents, Pictures, Videos, and Desktop to an external drive or network location. Additional folders can be included by adding them to a library.
