The whole disk partition is due to the wrong option selected during the reinstallation of the system, resulting in the entire disk partition, and all the data will be lost after the installation. If you want to restore the data of the lost disk, you need to pay attention not to save new files to the current disk (because the files saved now may overwrite the data of the original DEF disk). You can remove the hard disk and hang it on another computer as a secondary disk or connect a mobile hard disk to restore the data to the mobile hard disk. See below for specific recovery methods.
Tool/Software: Meteor Data Recovery Software
Step 1: After Baidu search and download the software to run, double-click the partition that needs to be restored, then unzip it and right-click the software icon to select the "Run as administrator" software.
Step 2: After the software is opened, directly double-click the physical disk to be recovered, and the full disk partition needs to recover data from the physical disk.
Step 3: It usually takes a few minutes to half an hour to wait for the program to scan, just wait a little patiently.
Step 4: The software will quickly put the found data into the "Recovered Partition" directory.
Step 5: Check the data to be recovered, then click Save in the upper right corner, the "Save File" button, and copy the checked file.
Step 6: The last step is to wait for the software to copy the data.
Note 1: If you want to restore the full disk partition, you need to pay attention. Before data recovery, do not save new files to the C drive.
Note 2: The data recovered from the entire disk partition needs to be temporarily saved to other disks.
