To address the issues of incorrect tachograph/driver card data download or an incorrect USB mass storage label (not showing as T5S or Tacho5Safe) when connecting your device to a PC, there might be a problem with the file system.


To resolve this, please follow these steps:


  1. Check the device's file system: 
    • Right-click on the device in your PC's file explorer and select "Properties."


    • Go to the "Tools" tab and click "Check." 
    • Click "Scan and repair drive."
    • Wait for the repair process to finish, then close the window. 
  2. Verify hidden files: 
    • In Windows File Explorer, click the three dots (...) in the top menu bar and select "Options."  
    • Go to the "View" tab.
    • Select "Show hidden files, folders, and drives."
    • Uncheck the box for "Hide protected operating system files (Recommended)."
    •  Click "Apply." 
  3. Check for corrupted folders:
    • Open the "Tacho5Safe" mass storage device in Windows File Explorer. 
    • If you see a "Found.000" directory, the file system is corrupted. You will need to format the device (see step 5). 
    • If you do not see a "Found.000" directory, the file system is correct.
  4. Restore folder options:
    • Return to the "View" tab in "Folder Options". 
    • Deselect the "Show hidden files, folders, and drives" option. 
    • Check the box for "Hide protected operating system files (Recommended).
  5. Format the device: 
    • Right-click on the device in your PC's file explorer and select "Format." 
    • Set the required parameters for the format.
       
    • Click "Start" and wait for the formatting process to complete.


Your device's file system should now be correct.
