unformat sd card on windowsIt’s very common to unintentionally format your SD card while fixing errors or repairing a failed SD card. In some cases, you might format the SD card to a different file setting. Either way, formatting wipes out all your data from the card.

The good news is that you can recover data after a format and essentially “unformat” SD cards. This article will show you how to unformat an SD card on Windows, Android, or a Camera.

Is it Possible to Unformat an SD Card?

Note that there is no “unformat” or reverse format function available on any device. However, you can attempt to restore the formatted data by employing various techniques. First, you need to determine the method used to format the SD card.

A quick format leaves the actual partitions containing your data untouched and marks the storage space as available for writing new files. Thus, you can use the period between the quick format and saving new files to your SD card to recover data from it.

📜 However, when you perform a full format, your PC erases all data permanently. Unlike a quick format, the full format writes and overwrites zeroes to the drive and scans for bad sectors to exclude them from being used as storage space. In such cases, the SD card unformat becomes impossible. Devices like cameras usually perform a full format by default – thus making data recovery impossible.

How to Recover Data from a Formatted SD Card?

The most efficient method to unformat (nullify the format’s effect) or recover data from a memory card is to use professional data recovery software. These tools are designed to recover your lost data efficiently. While several tools are available on the market, Disk Drill is a reliable option to recover data from your SD card.

Disk Drill is an industry-leading data recovery tool with an intuitive interface that first-time users can adapt to quickly. Moreover, it can help retrieve about 400+ file types. What’s more, the Windows version offers up to 500MB of data recovery for free!

If you’ve ended up formatting your SD card and want to retrieve data, remember to stop using the SD card immediately. If you continue using the formatted SD card, your deleted files will get overwritten – complicating data recovery and making it impossible.

Here’s how to unformat SD card for free using Disk Drill on Windows:

  1. Download and Install Disk Drill for Windows.

  6. Once you’ve selected the files you want to recover from your formatted SD card, click the Recover button. Alternatively, you can leave all boxes unticked and click Recover all.

How to Reformat an SD card?

Since you’ve recovered the lost data, try to reformat the SD Card to ensure compatibility with portable devices (smartphone, camera, etc.) Reformatting reverts the SD card’s file system to the previous state – thus facilitating smooth read/write cycles.

You can reformat the SD card on Windows, your Android phone, or in-camera:

How to Format an SD Card on Camera

The steps to format a camera SD card vary depending on the camera brand. For this article, we are formatting using a Canon camera:

  1. Turn on the camera with the SD card inserted. Now, press Menu.
  2. Select the wrench icon, and then choose the card you want to reformat.

  3. Now, select Format. To perform a quick format, select OK directly. But to perform a full format, press the INFO button to checkmark ‘Low-level format‘ and then choose OK.


Although there is no native unformat option available on any device, you can attempt to recover lost data from an SD card using data recovery software like Disk Drill.

To prevent significant data loss, you must create backups of your files before formatting. You can do this using cloud storage, storage devices, or byte-level backups from Disk Drill and keep your data safe.


You can unformat an SD card on the phone without a computer using two different ways. They are:
  1. If you don't have a prior backup, download an SD card recovery app on your Android phone and use it to retrieve your lost data.
  2. Recover your data by downloading a Google Drive backup on your phone. This way, you can recover all your pictures, videos, chats, music, and other files from Google Drive.
Unfortunately, there is no definite way to unformat an SD card without a recovery program. The Attrib Command can technically "restore" data. However, it only works by fixing errors that may have caused your files to go missing. In case there isn't an error that caused the formatting, you won't be able to unformat the SD card using this method.
Formatting an SD card as internal storage on Android means that the card will only work on that particular device. To unformat an SD card as internal storage, follow these steps:
  1. Back up all the data on your device. Now, decrypt the SD Card from the Android Internal Memory.
  2. On your phone, go to Settings > Storage > Storage Settings.
  3. Tap Format as portable.
  4. Then, tap "Format."
  5. Now, unmount the SD card from your Android after making it portable again.
  6. Finally, use SD card recovery software to retrieve lost data and unformat the SD card.
