I'm working with the developer of the Applesauce disk imaging tool in order to iron out some issues with 8" disk support.
I'm using a Qumetrak 842 disk drive that's got support for both double and single-sided media. This means that it's equipped with two index hole sensors, slightly offset from one another. It's my understanding that single-sided media has the index hole in one spot on the jacket, and double-sided media has one in a slightly different location.
The issue at hand is some NIB Dysan double-sided 8" media I have - the disks have index holes in the jacket in both locations. Is this typical, or do I have some weird "special" disks on my hands? The Applesauce author posits that the combination of the dual-sensor drive and the dual-hole media wouldn't typically find themselves together. Is this accurate? If it's not, how would a system contemporary with the media have handled the two index holes?
