Hard disk partition failure caused by Ghost restore system

Reason
A colleague told me that his computer system could not be booted. It turned out that he used Ghost for system restore. In the past, his 40GB hard drive was divided into five zones: C, D, E, F, and G, using dual systems. Windows 98 is installed in Zone C and Windows 2000 is in Zone D. One day his Windows 98 had some problems, so his colleague went into Windows 98 and ran Ghost to restore it. When running to 40%, the system appeared blue screen, crashed, restarted, and the system could not boot.
Task
Since the E, F, G disk holds a large amount of precious materials accumulated by colleagues for many years, he repeatedly asked me not to lose data when troubleshooting! This also makes me have to be very careful. Indeed, there is nothing more precious than data.
Determining the battle
After receiving this task, I went to fight, according to the phenomenon and requirements, I thought it is not difficult to solve this problem. After booting, the BIOS found that the BIOS can correctly detect the hard disk and capacity. Booting the system with a floppy disk, can go to the C drive, but can not read the data, the machine can still be started normally after formatting the C drive with the FORMAT C:/S command! Use the Fdisk command to view the hard disk partition, but found that there is only one partition, or extended partition. D, E, F, G partitions are gone!
In order to ensure the security of the data, I did not proceed with the reconstruction of the partition. The KV3000 was used to detect and found that the partition table of the hard disk had a problem and was repaired. Then use Fdisk to view the partition situation. You have found two partitions C and D, and can correctly display the capacity of the C and D disks and the total capacity of the hard disk. This is a good phenomenon, but the three partitions E, F, and G are still not found, and important data is on these partitions. Nothing can be done, I will be a living horse doctor, first install the operating system and then say. Since Windows 98 was originally installed on the C drive, Windows 98 was first installed on the C drive. You can check the C and D disks first during the installation process. The C drive is normal. The D drive cannot be checked. The -is parameter cannot be passed. Windows 98 does not install properly and installs Windows 2000. When installing Windows 2000 to select the drive letter, there are C, D, E, F, G partitions and corresponding sizes. Install the system on the C drive. After the installation is complete, the system starts up normally. After entering the Windows 2000 system, I still can't find the E, F, G disk. However, I have seen E, F, G disks when installing Windows 2000. Exit Windows 2000 and enter DOS. Use Fdisk to view the partition status. Or find only the two partitions C and D. Its capacity is not the capacity of the entire hard disk. So I thought of using the hard disk management tool Partition Magic to check the partition situation, then I went to Windows 2000 to execute it. When I started Partition Magic, I got a lot of bad clusters of the D message, and I made a one-to-one repair. At this time, in "My Computer", E. F and G partitions see the sky again, and the hard disk partition failure caused by the Ghost restore system is solved.
Thinking
1, this problem is caused by colleagues running Ghost under Windows 98, I hope that you will use Ghost in pure DOS, otherwise there will be an accident.
2, can not find the various partitions of the hard disk, the main reason is that the hard disk partition table has a problem, may use Fdisk MBR parameters may be able to help.
