Hi Ethan, I'm using new Athana 5.25 disks with the 8050. They should work fine. I found the following information in the 8050 Troubleshooting Guide at Zimmers.net: PROBLEM: drive appears to load but won't run. SOLUTION: check 6532s and UK3 controller ROM. PROBLEM: drive won't write/format. SOLUTION: check write protection tab in disk and switch on drive. check write circuitry on analog board. check write enable on digital board. Unfortunately, I have no idea where these circuits are located or how to check them. I don't even know where to find parts. I appreciate any and all help. Thanks!
