The drive will now "see" all 3½" disks as DD, regardless of their actual specifications, so as long as you only use the disks on the CPC, you don't even need to close the HD-index-hole, though you will still need to do this on your PC. This peculiarity of this drive also means that you probably don't want to have it in your PC, as you probably wouldn't want to modify your PC drive to DD-only just to be able to exchange disks between CPC and PC.
