Hard Disk Partition failure caused by system restoration using Ghost

Cause
A few days ago, my colleague told me that his computer system could not be guided. It turns out that he used Ghost for system restoration. In the past, his 40 Gb hard drive was divided into five areas: C, D, E, F, and G. Windows 98 is installed in Zone C and Windows 2000 in zone D. One day, he had a problem with Windows 98, so his colleague went to Windows 98 and ran Ghost to restore it. When he ran to Windows 98, the system experienced a blue screen, crashed, and restarted. The system could not boot.
Task
Because E, F, and G disks store a large amount of valuable data accumulated by my colleagues over the 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.
Decisive battle
After receiving this task, I went to the competition. According to the phenomenon and requirements, I thought it was not difficult to solve this problem. After the boot, the BIOS can correctly detect the hard disk and capacity. Boot the system with a floppy disk. It can be switched to drive C, but cannot read data. After formatting the drive C with the format c:/S command, the machine cannot start normally! Use the Fdisk command to view the hard disk partition, but find that there is only one partition, or an extended partition. D, E, F, and G partitions are all gone!
To ensure data security, I did not recreate the partition. Use KV3000 to detect and fix the Partition Table of the hard disk. Use Fdisk to view the partition information. You have found the C and D partitions and correctly displayed the C and D partitions and the total disk capacity. This is a good phenomenon. However, the E, F, and G partitions are still not found, but important data is stored in these partitions. No way to do it. I will use my dead horse as a medical doctor. Install the operating system first. Since Windows 98 was originally installed on drive C, Windows 98 was first installed on drive C. You can check disk C and disk D before installing disk C. disk C is normal. disk D cannot be checked, and the-is parameter cannot be used. If Windows 98 is not properly installed, install Windows 2000. When Windows 2000 is installed and the drive letter is selected, each partition and corresponding size of C, D, E, F, and G appear. Install the system on the C drive. After installation, the system starts up normally. E, F, and G disks cannot be found after you enter the Windows 2000 system. However, the E, F, and G disks are displayed when Windows 2000 is installed. Log out of Windows 2000 and go to DOS. Use Fdisk to view the partition information. You can find only the C and D partitions. the disk capacity is not the capacity of the entire hard disk. So I thought of using the hard disk management tool Partition Magic to view the Partition situation, and then went to Windows 2000 to execute it. When I started Partition Magic, many bad clusters of D disk were prompted, and I fixed them one by one, at this time, in my computer, the E, F, and G partitions are the same day, so far the hard disk partition failure caused by the restoration of the system using Ghost can be solved.
Thoughts
1. This problem was caused by running Ghost on Windows 98 at the beginning. I hope you will use Ghost in pure DOS later. Otherwise, an accident may occur.
2. the hard disk partition cannot be found. The main reason is that there is a problem with the hard disk partition table. The Fdisk MBR parameter may be helpful.
