Disinfectant requires the hierarchical file system (HFS), which is not
present on the 64k ROMs.  The "Hard Disk 20" file is a special system file
which can be used on these old machines to add in HFS.  This is all a bit
confusing, because even though Disinfectant requires HFS, it can still scan
both MFS and HFS disks.

I don't know where you can get a copy of the Hard Disk 20 file.  Try
dealers, user groups, whatever.  Or perhaps someone else here on the net can
help out and send you a copy.  (I don't have one, or I would be happy to).
