Here’s a quick video that explains recovery sessions in Disk Drill for Mac:

Every time you run a scan for your lost data, Disk Drill creates a file with .ddscan extension in the specified workspace location, and uses it to store the recovery session progress. This file will allow you to load the scan and perform data recovery at any convenient time without having to re-scan the drive or device again.

💡 Note: recovery sessions employ a different file format in Disk Drill for Mac and Windows, the session files are not compatible between editions. This article explains recovery sessions in Disk Drill for Mac OS X/macOS.

Disk Drill session file.ddscan is a proprietary format that Disk Drill uses to store the information related to one’s recovery scan progress. These files are meant to be opened with Disk Drill recovery software in order to resume the scanning session or assess the results of a specific scan in the past.

These recovery sessions can be loaded into Disk Drill if you want to continue file retrieval from where you stopped. You can always review the results of your saved scan, but you will still need the original storage device to resume the actual recovery.

This saves you time by eliminating the need to re-scan your disk all over again, if for any reason you had to stop the initial process. It’s not recommended to resume saved sessions in case the data on the storage device could’ve been altered after the initial scan. In such cases, please consider starting a new scan. Also, the general recommendation is always to recover your data as soon as you can, try avoiding any unnecessary delays; we hope you won’t need to use the recovery sessions feature explained in this article.

⚠️ Remember: Due to various complexities of data recovery, the longer you wait, the lower your chances are for successful file restoration.

Creating a recovery session file

Disk Drill saves recovery sessions in files that can be imported back in order to continue past scans from where you stopped. As mentioned above, the saved scans will have .ddscan extension when viewed in Finder.

Here’s how a recovery session can be saved for later:

  1. Open Disk Drill and start a new scan.
  2. Pause the scan using the “Pause” button at the top of the Disk Drill window.
  3. Go to the “File” menu and select “Save session as…“. Alternatively, you can use the Shift+Command+S key combination.disk drill save scan session
  4. Select the desired destination. That is where your .ddscan file will be stored.
  5. Done! You have saved the session. It can now be loaded into Disk Drill and resumed at any time.

Resuming the latest scan

There’s no need to manually save your scan session, unless you have to. Disk Drill will automatically create a resumable one either after the scan, or during a scan, depending on its duration. Also, Disk Drill has a way to easily Resume a previous scan.

Here’s how:

  1. Open Disk Drill.
  2. Select the device you were scanning before.
  3. In the bottom-right corner, above the “Search for lost data” button, locate the text saying "Last scanned: x hours/minutes ago" and click it. It will load the last scan that was performed on the device.disk drill resume data recovery
  4. Now you can recover the data that was found by the scan, or press the “Play” button on the top of the page to resume it.disk drill resume data recovery from session file

💡 There is the Recent Sessions section on the left side of the Disk Drill home screen. You can quickly resume any of the last several scans.

Loading saved scans into Disk Drill

If you have a saved session file, it is easy to load it into Disk Drill and continue the scan or recover the files based on the scan data. Here’s how:

  1. Open Disk Drill.
  2. Go to “File” menu and select “Open recovery session”. Or use the Command+O keyboard shortcut to do that.disk drill open saved recovery session
  3. Select the .ddscan file in the pop-up file menu.
  4. Press the “Load” button after selecting the .ddscan file.
  5. Give Disk Drill a minute to load the data from the file.
  6. Press “Continue” to resume scanning.
⚠️ The .ddscan files 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.
