China DOS Union

Hello everyone!
My computer was originally divided into three partitions, C, D, and E, with capacities of 3G, 6G, and 6G respectively, 15G total. C originally had the WIN98 operating system installed. Later, after formatting the drive and installing a DOS system, I found that the other drives were gone and the drive capacity had become 2G. Using FDISK, I only found the C drive, and the total capacity shown was that much. How can I restore the original partitions without losing data? I had no choice but to format the drive and reinstall WIN98, but the problem is still the same. Please give me some advice, experts.

Is the disk you used to boot the partition DOS 6.0? Or is your partition FAT16? Those will all limit partitions to under 2G.

I just checked for viruses and found Script.Redlof.Htm. How can I restore the original partitions?

If you want to see hard disk partitions larger than 2GB, please use MS-DOS 7.10 or above.

"Later, after formatting the drive and installing a DOS system, I found that the other drives were gone and the drive capacity had become 2G,"
You definitely used a DOS 6.22 or earlier boot disk before formatting. That is the root of the problem.

First kill the virus, then FDISK /MBR

No use. Upgrading the system to MS-DOS 7.x is the key.

Boot with 7.x, kill the virus, and it should be fine.
