The disk was orginally FDISKED with MS-FDISK. There are extended

lose data on the extended partition.


Ok, I'm using an emulator, anyway. VMware, to be specific, but Bochs is also possible.
What you can do, is , if you have a logical partition for which you have saved the data first,
run FreeDOS format from Win98, formatting that logical drive with FreeDOS format program, and then run scandisk on your
freshly formatted logical partition.


* Not using the /D switch and redirecting to a file.


not relevant (/D means very verbose output), and > output.txt is for capturing the output.
Does not affect the working of FORMAT.


* Not running FreeDOS FORMAT from an MS-DOS boot disk.

It seems appropriate to run FreeDOS FORMAT from a FreeDOS boot disk. Would
you mind elaborating a little? It is my general custom to have boot disks
with the SYS, FORMAT and FDISK corresponding to the DOS being used. So
that's the way I tested.


We try to create replacements, not just clones. FreeDOS programs should be able to run properly on an MSDOS kernel,
and clone the working. FreeDOS programs tend to be smaller (probably compressed by UPX exe-compressoor) and need not
so much memory.


Keeping in mind that I cannot delete the data in the extended partitions.

Please, outline a specific test procedure and I'll report back if you don't
mind?


OK, bootdisk contents:
msdos.sys
io.sys
command.com
fdisk.exe
format (FreeDOS version)
scandisk.*
himem.sys (or xmsmmgr.exe)

in Vmware, I have a 1GB harddisk setup. The size ensures I can create a FAT32 partition.
Boot the bootdisk with above contents (got my image from bootdisk.com)
I enable FAT32 support, I create one partition, primary, active, occupies entire disk space (1GB).
Then I reboot.
next, I do FORMAT C:
after that, SCANDISK C:
this gives errors.


I'll try to get some results myself, if I succeed in setting up my ramdisks.
In Bochs I use a 300MB file, which unfortunately also takes 300MB on disk. Copying a fresh version takes a while..
