How to recover HDD data with DiskInternals Partition Recovery

Data can be recovered by formatting the drive using Disk Management.

In general, using Disk Management, you can create a partition, delete a partition, format a partition, expand or shrink a partition. Therefore, if you accidentally used Disk Management to perform a format, your data can be recovered using format recovery software.

To format your hard drive using Disk Management, you should refer to the following instructions:

Step 1. Right-click the Start menu and select Disk Management or run diskmgmt.msc to open Disk Management.

Step 2. Decide on the partition you want to format, and then right-click it and choose Format.

Step 3. After selecting the volume label, allocation unit size, and file system, click OK. Be sure to select the "Perform a quick format" option if it's not set by default. Otherwise, you will perform a full format and then the data cannot be recovered.

Step 4. After these steps, just click OK, then the partition will be formatted very quickly, the data is not overwritten, and you can format the disk.

For data recovery, you still need to rely on the professional DiskInternals Partition Recovery application, which has many advantages over similar applications.
