As I understand it, the SCP doesn't need the index sensor in order to copy a disk, as long as you check the option in the menu. The only obstacle is with the drive itself, as many 1.2mb drives check for the presence of an index before switching to a "ready" state. Most 360K drives don't care and will happily read disks without an index pulse.
However, I only have one "flippy" that does not have an index on its back side, so I have not tested that much.
