A case of data recovery after “one key is divided into 4 areas”

Case:
The customer wanted to reinstall the operating system by himself, and the operation error chose to divide it into 4 partitions in one button. As a result, all the data were gone. It turned out that there were two partitions. Now you want to restore all the data of the original D drive.

Solution:
I first scanned it with R-Studio, and found that there was a partition in R-Studio that was very consistent with what customers said. A green partition was scanned. Green means that DBR is good. Later, I found this partition with Winhex to find this partition.The DBR is then written back in the partition table with Winhex to restart the perfect recovery of the data.
