To recover data that was on your hard disk, use third-party data recovery tools such as EaseUS, Restore My Files and Recuva. Whereas Recuva and Restore My Files only work with Windows PCs, EaseUS is compatible with Macs.
To recover using EaseUS, first download the appropriate setup file from the EaseUS website, depending on your operating system. Install the program, launch it, select the file types you wish to recover, and click Next to move to the next step of the wizard. Select the drive where you lost your data, click Scan, and wait for the program to locate the data. Once the scan is complete, a list with recoverable files appears. Select the files you wish to restore, and click Recover.
To recover using Recover My Files, first download the setup file from RecoverMyFiles.com, install it, and run it. Once the wizard window appears, select Recover Files, click Next, select the letter of the drive from which the files were lost, and click Next. Select Search For Deleted Files, and click Start. Once the scan is complete, check the search results for the files you wish to recover, select them, and click Save Files. Select the destination drive for the files, and then click OK to save the files in that location.
