Super partition table reconstruction tool

The computer has two 160G SATA hard disks. When Win7 is installed in the system disk management, the partition is not completed for half a day, so it is forcibly closed. After restarting, I can't enter the system anymore. I feel that it should be the operation problem just now. Unsurprisingly, unplug the hard drive (non-system disk) and you can enter it. Obviously, the disk has some problems. With PQ, DM, etc., all useless, as long as the hard drive is hung up, nothing can be done, even WIN PE can't go in. The first thing that comes to mind is the disk partition table error, because the operation I did could not lead to more serious problems, but there is no more professional tool at hand. After getting an afternoon, I still didn't play. I suddenly thought about why I didn't use the Linux installation disk to see if I could find the disk. Linux really is amazing, find the disk, delete the original partition of the disk, hehe, etc., don't go any further, I am not installing the Linux system, well, it is here. Restart the system, you can enter the system, the second disk all show unallocated, and now mainly to retrieve the partition structure. Looking for a while on the Internet, I found a very powerful: easy to partition my table doctor, find the partition is super accurate, my original hard disk above the NTFS partition and EXT3 partition can be found and restored.
