I have two MSDOS.SYS files on each drive (C and D) note that among
other things that HostWinBootDRV= are not the same is this a
problem.
Other issue is that I have been unsuccessful in making a mirror
image on
disk D of disk C. I am trying to make a backup and leave it in the
closet (updated once in a while) until drive C dies. Trying to
make a
working D backup really has me confused. C: works as single
drive but
when I try D the best I have able to do is get the command prompt and
that wont let me reconize Floppy ????. Sorry win 98SE and I am only
showing MSDOS from C: drive but the same is on D: drive. I understand
Master/slave drive jumpers settings. Thanks for words of wisdom.
Oh yes
drives are not the same capacity80 GB and 20 GB

-----------------------first file is located C:\
[Paths]
WinDir=C:\WINDOWS
WinBootDir=C:\WINDOWS
HostWinBootDrv=
UninstallDir=C:\

[Options]
BootMulti=0
BootGUI=1
BootDelay=0
Boot Menu=0
Boot Menu Default=2
DblSpace=0
DrvSpace=0
DoubleBuffer=0
Logo=0
AutoScan=1
WinVer=4.10.2222

--------------------------The second File is located C:\C drive root
[Paths]
WinDir=C:\WINDOWS
WinBootDir=C:\WINDOWS
HostWinBootDrv=C
UninstallDir=C:\

[Options]

You don't want to make a mirror image - you want to make an exact copy.
You can't do that if the drives are different capacity, unless you are
prepared to limit the larger drive to the size of the smaller drive.

You can make a working backup of the C drive. This means that if the
current C drive dies then you remove it from the machine and insert the
backup drive. The machine then boots into Windows and your files are there
for you to use. There is drive imaging software available to do this, but
your drive size difference will make it tricky.

You can do it manually - sort of. If I was doing this I would install the
backup drive as the primary drive on the system, partition and format it,
then install and configure Windows and the applications I want to backup. I
would then test that it's bootable. Then I would move it to the slave,
install the primary drive, and copy the important data files to the backup
drive.

An alternative is to use backup software and create the backup file on the D
drive. In this case, if a restore is required you would first fix or
replace the master drive, install Windows (or at least whatever was required
to enable you to install and run your backup software), install the backup
software, and select the restore option, nominating the file you had saved
on the backup drive. How much of the Windows configuration this restores
from the backup depends on the backup program you are using.
