Sep 7, 2024 at 7:11 comment added Netch @ChrisDodd Thanks for the notice. So there was a principal difference in mechanical design of the drives that Agat versions (by "Izot" from Bulgaria) didn't tolerate this clatter. The drives utilized a flat plastic disk with a spiral furrow residing on a stepping motor shaft; R/W head was linearly moved by the groove "plough". (Sorry for terminology mismatch.) Maybe tuning would have been easy but at school we weren't having respective tools...
Sep 5, 2024 at 21:58 comment added Chris Dodd Apple ][ disks don't have a zero track sensor and use the same "unconditional step down" when booting to access track 0, resulting in the distinctive loud clatter from the drive hitting the end stop when booting. I don't recall seeing problems with the head getting misaligned, however.
