Record data recovery experience

I bought a notebook a year ago. I didn't change it when I installed Windows 7 at the factory. I have been using it all the time. However, it is not appropriate to drive Windows 7 in recent projects. I couldn't decide to switch to Windows XP yesterday, can we always change the system at the end?

Let's talk about things. XP is a normal operation. I took out the ghost installation disk for normal installation. First, I changed the hard disk interface to the compatibility mode. My hard disk is 320 GB and divided into four zones, in XP, I can only identify drive C and the remaining three disks as one disk. I am very surprised. What is the problem. Of course, there is also a reserved partition (100 m) for win7. At this time, I will delete the M reserved partition, delete the C disk, and then combine the two disks into a C disk under XP, after deleting the C-drive partition, a terrible thing happened. After identifying the hard disk in XP, It is the GB partition. At this time, my hands have been sweating, an ominous hunch.

I initially thought that the hard disk partition was deleted. I should use a tool to fix it and use PE to guide it. But PE cannot recognize the hard disk at this time.

Finished.

Then I called Lenovo and asked how it would be like this. I was told that the win7 partition was like this in XP, and I was too easy to learn.

Then I went to the technology market over the weekend to buy a shell that can hold my laptop hard disk. I split the hard disk and mounted it to another machine, you can only identify a partition that has no partitions of about GB.

I started to identify the original partition by using the data recovery tool and found the E and F disks. Fortunately, d disks have nothing to do. Copy the data of these two disks and reinstall them.

It took two days to waste. Pay attention to it later.
