Got a new CA-42 cable. The "old" DKU-5 did not work. Hooked up the CA-42, inserted the paper card between the PCB and head connector, hooked up the HD to an independent power supply and, launched the hyper terminal, everything worked just fine. I used this guide. Got to the point when I should enter: m0,2,2,0,0,0,0,22 HD spins down. Nothing happens for 30 minutes. Turned off. Repeated everything. Tried F712 command and got this response: Byte:05A1: Expansion = 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 This time waited 45 minutes. Nothing. Read another 2 hours not much learned. I've got an SD35 firmware. Maybe that's the issue? Anyone can help? Please.
