Reading Time: 4 minutesAccidentally formatting a USB drive can result in important data being lost. While you cannot undo a format, you can still recover the data you lost and effectively unformat a thumb drive, provided you act quickly. The sections below will explore this in a detailed and easy-to-understand manner.

Is it Possible to Unformat Flash Drive?

While Windows doesn’t offer any feature to reverse a format, the wiped data can still be recovered depending on a few factors. So technically, you can unformat a flash drive and undo the damage that has been done.

In Windows, you can either perform a Quick Format or a Full Format. Data recovery after a Quick Format is quite easy, and you can almost certainly recover all the data that was lost, provided you didn’t write large amounts of new data to the thumb drive. A Full Format, on the other hand, overwrites all the data on the drive with zeroes, making data recovery impossible.

Luckily, the Quick Format option is ticked by default on Windows, so chances are that you performed a Quick Format on the pen drive.

If you used third-party data shredding software to format the USB drive, it is usually impossible to recover the data. Your best bet in this case, is to contact a professional data recovery service.

Another important factor affecting USB drive data recovery, is whether you wrote new data to the drive. Creating new files overwrites the previous files and permanently wipes them out. Regardless, you should still scan the thumb drive using data recovery software, as some of the files will still be recoverable.

How to Increase Chances for Successful Data Recovery From a USB Drive

Being proactive and keeping good data recovery etiquette in mind goes a long way in determining the extent of data recovery from a USB drive. Here are a few useful tips that will help you unformat a thumb drive with maximum success:

  1. Stop using the USB drive immediately. As soon as you notice the data loss from your pen drive, securely eject it and don’t reconnect it to your PC until you need to perform data recovery.
  2. Don’t write new data to the drive. Copying new files to the pen drive will overwrite the data you want to recover and make it impossible to get back.
  3. Perform data recovery as soon as possible. Delaying data recovery will only increase the chances of accidentally writing new files to the drive.
  4. Use a good data recovery program in the first data recovery attempt itself. The first data recovery scan is usually the most successful. Repeated scans further stress the drive, therefore use a good data recovery program from the get go.
  5. Follow the steps in our data recovery tutorial carefully.
