The write protect notch on 8" disks has the opposite behavior of 5.25" disks. I recently repaired a CGRS Microtech PEDISK II 8" disk system for PET. I had to work through the same issues with the index hole location and write protect notch. Now that my PEDISK II system is working, I can provide a known good 8" single sided, soft sectored, single density (FM) formatted disk with 77 tracks, 26 sectors per track, and a 128 byte sector length. Disks from my system have been successfully read on another. The filesystem is not be compatible with CBM drives but the disk can be used to test sector read and write.
