1. Restore data from hard drive with hard drive recovery software

If you still cannot get data or access the saved data on the hard drive after reconnecting the hard drive properly to your PC, you'll need the help of professional hard drive recovery software.

EaseUS hard drive recovery software will help you get data from an inaccessible hard drive without any obstacles.

Effective tips for a successful HDD data recovery with EaseUS HDD recovery software:

  • Your Hard Disk Drive (HDD) can be either an internal or external one. If it's an external HDD, you must correctly connect it to your computer using a proper cable, and it's going to appear in the "External Devices" section in EaseUS Data Recovery Wizard.
  • If the HDD data was lost due to a quick format, partition loss or deletion, switch to the "Lost Partition Files" tab to check the scan results after scanning the HDD.

Here's the standard process to scan and find lost data on an HDD:

Step 1. Choose your HDD partition(according to its drive letter or partition label) as the target disk and click the Scan button.
