That would be a > good start... They wouldn't necessarily have to sacrifice capacity per-se. The current problem is that unlike SCSI disks, you can't seem to reformat SATA ones to arbitrary sector sizes. However, I could see the SATA manufacturers selling capacity at 512 (or the new 4096) sectors but allowing their OEMs to reformat them 520 (or 4160) and then implementing block guard on top of this. The OEMs who did this would obviously lose 1.6% of the capacity, but that would be their choice ...
