Disk Mirroring Programatically?

NTDEV
1

I want to be able to break and create disk mirrors programatically under
Windows NT 4 and/or Windows 2000. My “embedded” system has a known
configuration of 2 drives of the same type, so it won’t have to have much
complexity.

I assume this is possible through some API, since Disk Administrator does
the management and it’s the FTdisk driver that actually does the work. Or
maybe it is really just doing some Registry writes for FTdisk to “discover”
when the sytem boots?

Frankly, even a command-line program would be satisfactory (maybe even
better) since my program could just spawn off a command to do the work.

Any ideas where I should start? I can’t find any info in MSDN or the usual
web sites.

Thanks!

Can NTDDFT.H help?

Good find! That’s the right header file, but apparently it is undocumented
except for that. It would be nice if I can find the information on the
IOCTLs. I did some searches on “ntddft” now, and all I found was a
great-as-usual article that Mark R. wrote – unfortunately, it only covers
the Registry structures, not the IOCTLs.

Mark R.'s article, if anyone else is interested:
