Amazing data recovery

Today, a teacher from the Ministry of Sports called me and said that the computer could not be started, prompting me That the boot disk could not be found. I thought it would be Lenovo's protective card, but I had to take the tool disk to solve the problem, first, the hard disk can be found in the bios, but the hard disk protection card cannot read the partition information. Later, the hard disk protection system was simply unloaded, and then the winpe system was started with the deep-colored blade V30, no partition can be found, but a hard disk with no partition can be seen in disk management.
After analysis, the partition may be damaged because the shutdown is illegal. You can use ptdd Partition Table doctor 3.0 to automatically restore partitions. In less than half a minute, you can see partitions in ptdd. The system prompts that a restart is required to take effect and immediately takes out the disc and restarts. The problem is solved.
Fortunately, I am lucky enough. The damage is not very big this time, or it may be difficult to recover. Of course, it is also the ptdd function first.
