Thank you for posting in Microsoft Community.
I understand that you'd like to save files in your USB drives without errors. I appreciate the effort in providing a clear photo showing the error.
Please perform the methods below:
- Check the settings for new/remaining updates. Go to Windows Settings > Update & Security. Check also if Optional updates are available.
- Run the Surface Diagnostic Toolkit.
- Run the System File Checker.
- Install the driver package manually.
- Check the specific OS build of your Windows Settings> System> About.
- Download the driver and firmware for Surface, choose Surface Pro 4 and click download on the next page.
- Please choose the .msi file that matches your current OS Build and click Next.
- After the download, runand installthe .msi then Restart the Surface Device
If the issue still persists, perform the USB recovery process. This process will wipe everything out on your device and install a fresh operating system. Please make sure that you have back up your files and data either in an External Hard drive or use your OneDrive app. You’ll need a USB (USB stick) with at least 16GB/32 GB and format it clean (make sure that you have chosen FAT32 as the file system while formatting the USB). You'll need a PC running Windows 10 or Surface Device to download the system files/recovery image on the Microsoft Website. Note: USB/Flash drives are the only required device for you to perform the follow steps below successfully.After formatting the USB to FAT32 USB, convert the FAT32 USB stick as a bootable device.

Once the download is finished, go to the file, right-click and choose Extract all then choose the USB/Flash drive.
• Perform the USB recovery:
