A lot of data recovery solutions out there offer a free trial that only gets you as far as previewing recoverable files. Once you attempt to retrieve them, you’ll get hit with a message asking you to purchase the full version. Check if the software has a free version that allows actual recovery.
Whether it’s pictures, documents, audio, or file types, it’s a good idea to select a recovery program that supports the retrieval of a wide range of file extensions. Once you’re done recovering your files this time around, you may need to use the program again in the future for a different file type.
While there are a few genuinely free data recovery programs out there and some with a decent trial version, they’re often either overly complex, ineffective, or have recovery limits. So if you’re willing to invest, you should find a program that fits your price range. Also, consider whether you’d prefer a program with subscriptions or a one-time payment.
Install the application on a macOS or Windows machine
Launch the program and choose the disk or partition that contained the deleted data
Begin scanning for lost data by hitting the Recover button
Select the data to be restored from the preview panel and click Recover to start recovering the files
Keep food and drink away from your work computer. This one goes without saying, but you’d be surprised by the number of people who keep food and drinks dangerously close to their laptop or computer. No matter how careful you are, uncontrollable circumstances may occur that could cause a spill onto your machine, potentially compromising your data.
Invest in a surge protector. A major power surge can do heavy damage to your computer. A strong enough one could fry the components in your computer, taking all of your important files along with it. So if you live in an area with unpredictable electric currents, spending some money on a surge protector can be a lifesaver.
Password protect your machine. If you live in a household with multiple people, then it’s a good idea to put a strong password on your computer or laptop. You never know when a child or another unauthorized person might try to make their way into your machine and fiddle with your files. Better safe than sorry.
A quality data recovery program should allow for the retrieval of a wide range of different file types, whether they’re documents, images, audio clips, and others. Disk Drill is an excellent option that is capable of recovering SDF extension and you can easily filter out the results by typing the extension into the search bar at the results screen.
On Windows PCs,SDF files that weren’t permanently deleted using the Shift + Delete command can be found and restored from the Recycle Bin tool. For Macs, all deleted X files are sent to the Trash first, so you can get them back from there. Otherwise, you can use Windows File History if you enabled it before the deletion or the Mac Timeline feature.
If you find that SDF files are randomly being deleted from your computer, it’s a good indication that your hard drive is failing. In these cases, it’s a good idea to make a backup image of the drive to avoid further data loss. Another reason is that your computer has been infected by a virus or some form of malware.
