Passport drives that have suddenly stopped working can be a frustrating experience, especially when crucial data like your Quicken files is at stake.
To troubleshoot, first, check for any physical damage to the drive and attempt to connect it to a different computer or USB port to rule out connection issues. If the drive is still recognized but you cannot access your Quicken data, consider using reputable data recovery software like Stellar Data Recovery, EaseUS Data Recovery, or Disk Drill.
Alternatively, if the old Passport is accessible, manually copy your Quicken data to a temporary location on your computer and then transfer it to the new Passport. Always ensure you have a backup of your Quicken data and explore any migration tools provided by the external drive manufacturer.
Remember, regular data backups are crucial to prevent such issues in the future.
