  • A JavaScript error occurred in the main process
  • L501, L502 and L503 errors
  • Error raised while initialize data service on your Ultimate Backup drive
  • Error raised while initialize data service on your computer

Here's how to use it:

1. Connect the Ultimate Backup to your computer (do not open the LaunchUltimateBackup app)
2. Click this link to download the Repair Tool (if you are a Mac user, click this link instead)
3. Find the "RepairTool" file in your Downloads folder, and double click to open the Repair Tool

4. Click the gear icon in the top right corner

5. Click Reformat Drive (Support Only) in the dropdown menu
