This only applies to software that uses the BIOS for disk I/O. Basically
this means bootloaders and somtimes first-level bootstrap routines (DOS
also). Modern OS's always have their own hardware drivers for disks.

Basically anything that can gain supervisor privileges on a windows system
can do whatever it wants with the hardware, even bypassing the OS's own
driver if need be (the latter requires that it understand the hardware of
course).
