Atari STart Magazine Cover Disks
STart magazine ran from Summer of 1986 to April/May 1991. It usually used single-sided disks, but in November of 1989 they switched to a double-sided format but using a special bootsector that made them look like single-sided disks.
This is called the "Heidi Format", and they explain it in an Editorial note.
But the end result is that these disks are double-sided, but disk imaging software may mistake them for single-sided. This happened when all the STart disks were imaged, so existing collections of the disks are actually missing half the content.
I'm trying to organize locating and re-imaging these affected disks.
