Very good idea, this should do it:

|REGEDIT4
|
|[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\FileSystem\NoVolTrack]
|"Any formatted disk 1"= hex:00,00,EB
|"Any formatted disk 2"= hex:00,00,E9
|"Any formatted disk 3"= hex:00,00,90
|"Any formatted disk 4"= hex:00,00,69

These four bytes are the opcodes the DR-DOS kernel looks for when logging
in floppy disks. I am quite sure MS-DOS/PC DOS does the same.

Alternative, one could create 256 keys like:

"Value 0"= hex:00,00,00
"Value 1"= hex:00,00,01
...
"Value 255"=hex:00,00,FF

to completely disable Windows Volume Tracking for any kind of disks.
I am currently experimenting with this... (If someone wants the
corresponding .REG file for this, just drop me an email).

BTW. Does someone know, if this "IHC thing" also happens under
Windows NT, 2000, or XP?

Greetings,

 Matthias
