Hmmm. Sounds like I should get the original drives from the VCF warehouse at Infoage.

This is where I'd suspect that the originals were written with a mis-aligned drive. I've run into this myself and have a drive reserved for "tweaking" the alignment. That is, it's not suitable for writing disks as the alignment is fiddled with, depending on requirements. Of course, disks written with a mis-aligned drive will read just fine on the same drive. --Chuck
