The Disk Drill data recovery tool offers a feature that allows you to easily pause a disk scan, with the intention of returning to it later and completing the scan. Disk Drill accomplishes this through the use of recovery sessions. Our tool also creates an autosave file when your scan is complete, so you can perform your recovery later at a more convenient time without needing to rescan the disk. These files are created with a .ddscan extension, and by default are opened by Disk Drill.

These recovery sessions will be loaded into Disk Drill if you choose to resume a scan or continue a recovery. When the tool presents you with a Resume option, it is offering to use a paused scan of the same disk you are scanning. The Continue option is used to load a previous scan and continue with your recovery.

Data Recovery Sessions

This saves you time by eliminating the need to rescan your disk. It also lets you run a scan and study the results at your leisure to determine what exactly you would like to recover. After making your determination, you can load the scanning session into Disk Drill and quickly begin the recovery process.

Remember: even though we provide you the tools to address your data recovery needs slowly, it is the time that is valuable. The longer you wait the lower the chances for a successful recovery.

In this article we will demonstrate how to use these recovery sessions to streamline your data recovery procedures.

Creating a Recovery Session

You can pause a Deep Scan at any time to create a recovery session that you can use to resume your scan at a later time. This can save you considerable time later. This is not always possible with every type of scan, other scanning methods need to run to completion and generally cannot be fully stored in session files.

A recovery session is created automatically when a scan is complete, so you can come back to it when you are ready to perform the actual data recovery.

Here is the screen you will be presented with when you first start Disk Drill.


We can see that there are some disks with a Recover button. These have not yet been scanned. There is also a Continue button for the disk TestDD1. It is alerting us that a previous recovery session was found for it. We now have the option to resume the last scan or start a new scan. If we have not used or accessed the drive since the previous scan, we can go ahead and use it as our recovery point and click resume to complete the scan.

Clicking “Resume last scan” loads the recovery session that Disk Drill created when you paused your previous scan. Rather than repeating the scan and wasting valuable time, you just restart it at the point it was paused.

Note: depending on how old the saved scanning session is, it might be smarter to start a new scan instead of resuming the one that might be outdated. This decision depends on how actively the target storage device was used after the saved session file was created.

Resume last scan

Steps to Resume a Previous Scan

  1. Start Disk Drill.
  2. Choose the drive you want to scan or recover.
  3. Click the Continue button to resume the scan or use the ‘Resume’ option in the upper right of Disk Drill to either resume your last session or choose from among your saved sessions.
  4. You can pause the scan again while it is running by using the ‘Pause’ option in the upper left of Disk Drill. The ‘Resume’ option restarts your scanning process as seen below.

Previous Scan

Steps to Create a Saved Session

When you have completed a successful scan, Disk Drill saves it automatically so you can continue your recovery at a later time. It creates a .ddscan file in the home folder of the user whose account is running the application. You can also save your session manually to a location of your choice. Here is what that looks like when you are using Disk Drill.

  1. Start Disk Drill.
  2. Choose the Disk you are interested in scanning and performing data recovery on.
  3. Click the Recover button and allow the scan to complete.
  4. You are presented with the list of files that can be recovered from your drive.
  5. Choose ‘Save Session’ in the upper left of the Disk Drill screen.
  6. Use the default name or choose your own and save the file. It will have a .ddscan file extension.
  7. You can now use this scan to perform recovery on the disk at a later time.

Recovery Hard Drive

The .ddscan files that are created by Disk Drill should not be modified before being loaded again. Doing so can invalidate the scan results and lead to unexpected results. Their sole purpose is to streamline your data recovery tasks by enabling you to scan, pause, and resume your scans at any point in the recovery process.

This is just another feature of Disk Drill that makes it a valuable tool that you should have installed on your machine for the unexpected but critical situation where you need to recover deleted data from one of your drives.
