Problem description: After
GHOST, only C drive is left because when the system was reinstalled, the wrong option was selected, which caused the entire hard drive to be installed as C drive. After installation, naturally only C drive is left. After the reinstallation, only one disk is left. The specific recovery method of the file solution is described below. 
Tools/Software: Extreme Data Recovery Software
Step 1: After Baidu search and download the program to run, select the disk that needs to be recovered, and then click the "Start Recovery" button. 
Step 2: It usually takes a few minutes to half an hour to wait for the software to scan. 
Step 3: After the program finds the files, the program will list the found partitions. 
Step 4: Tick all the data that needs to be restored, and then click Save in the upper right corner, "Save As" button, and COPY the checked files. 
Step 5: The last step is to wait for the program to copy the files. 
Note 1: If you want to restore GHOST, only C drive is left. Before data recovery, do not save new files to C drive.
Note 2: After GHOST, only the data recovered from drive C needs to be temporarily saved to other drives.
