Sandisk Extreme Pro USB 3.1 Data Recovery


While I was SanDisk SecureAccess Vault, I deleted all the files that were on the drive.

I wanted to see if I could restore the deleted data using Disk Drill and it was able to “find” the deleted data. However, the files are in the format that they appeared in the SanDiskSecureAccess Vault.

I don’t know what to do with the files in this format. If I extract them, they cannot be directly opened by me to access the data.

Is this a lost cause?

If you can’t restore the Secure Access app files your data files are no longer accessible.

If you can restore the Secure Access app files, you should be able to access your Secure Access data files.

If you no longer want to use Secure Data, open it one last time and save each of your data files to someplace on the USB drive, or your harddrive, then exit Secure Access and then delete the Secure Access app files and each of it’s encrypted files that you displayed above. Then you can access your data files on the USB drive directly.


By app files, if you are referring to SanDiskSecureAccessV3.01 and SanDiskSecureAccess Vault, they were never deleted (see screenshot 1)

The issue is that the files are in “vault format” when they are recovered (see screenshot2)

Yes, by app files I’m referring to the two you stated. So I’m confused, you have the app and you have the encrypted files, are you saying that when you use the SecureAccess app you can’t access your files in the encrypted vaults?


Disk Drill is able to locate and restore the files as they appear in the PrivateAccess Vault. Here is a picture of some files I was able to recover:

The question is, what do with those files so that they can be “opened” so I can access the content.

Those are not files in the PrivateAccess Vault. Those are sections of the vault. Sections that have been touched by Disk Drill and whatever deleted them from the drive. And as such PrivateAccess will not open them.

I’m afraid your user files are no longer available. Hopefully you still have the original user files on your harddrive.


Those were indeed the files in the vault. After restoring the full file structure with a deep scan, I was able to copy the contents to a formatted Sandisk USB drive and I was able to recover all the data.

If anyone else has this issue, it’s possible to recover your files with the right tools.

The issue is that the files are in “vault format” when they are recovered (see screenshot2).
