I don't think a PC equiped with a 3.5" drive can read a Mac formatted
disk.  A Mac formats the disk to 800K by using a variable speed
controller which puts more data on the outer rings of the disk than on
the inner ones.  I'm not sure if it's possible to override the ROM on a
PC, but this would be pretty extreme measures.  IMHO it's not really
neccessary to do this.

Again:

This is a misleading simplification.  WDEF spreads when a disk is
inserted if the Finder or MultiFinder is running (and when the disk is
opened).  If an application is running and not with MultiFinder, WDEF
doesn't spread it's infection.  So a Mac running Disinfectant (or a
commercial equivalent) w/o MultiFinder is quite capable of stopping
infections.
