That will not help. I'm not a Commodore expert, but I'm pretty certain
that C-64 disks were recorded with GCR modulation, not MFM (or FM). You
will not be able to read anything with the PC floppy disk controller.

Note that the incompatibility is not on the driver or the os, is at the
hardware level.
