All 7200.11 drives *should* communicate at 38400 Baud, so that should be okay. Just some pointers: Make sure TX, RX and GND are connected correctly (TX of RS232 to RX of drive, RX of RS232 to TX of drive, GND to GND) When the PCB is fully attached to the drive and you only apply power to it (so no SATA-data), you *should* hear it spin up as normal When powering up the drive (with RS232 attached) you should get some messages in the terminal display (even without CTRL+Z), like: LED:000000CC FAddr:0024A051 LED:000000CC FAddr:0024A051 When the PCB is not attached to the drive and you apply power to the PCB with the RS232 attached, you *should* get a prompt after pressing CTRL+Z (keys at the same time) Apart from that, I can't think of anything else Good luck, Peter. Hmm. I don't hear it spin up. That's probably the issue then. When the board is disconnected, I don't get anything, so that means my board is fried? Am I out of luck? Should I try a different board? I have a 7200.11 1 GB, and the boards look similar, but I'm guessing they aren't compatible.
