This doesn't seem like a blocking issue to me. The drive would report _something_ back whether the disk is damaged, or even missing from the drive entirely. The copy protection would simply rely on getting what it expects back from the disk drive controller which could be provided via emulation if some kind of standard is agreed upon to represent this.
