Dr Claw

I have tried with Putty, and am getting the same results. If the pcb is connected to the heads and the motor I see the 'LED:000000CC FAddr:0024A051' message, if I disconnect it from both or either of those with some card then I see nothing and CTRL-Z does nothing.

Setup the TTL device with the settings provided, connected the GND, TX, and RX wires, powered up the hard drive and waited for it to startup (waited from a few seconds to a few minutes over various attempts), then tried hitting CTRL-Z to bring up the prompt and got nothing. I don't know GTKterm well, or any other terminal software so I can't be sure that CTRL-Z has the same functionality as it does in HyperTerminal.

I have an ST3500320AS that recently locked itself in the BSY state. When connecting a USB to TTL device up as detailed in this thread, I get this message from the drive 'LED:000000CC FAddr:0024A051' which as I have read indicates the BSY state. I cannot get it to give a prompt to enter any command, I have tried with the pcb on the drive, completely removed from the drive, with some card between the pcb and the motor connection, and with some card between the pcb and the heads connection. I am using GTKterm on Ubuntu 14.04 with an FTDI Friend from Adafruit and am powering it with a power supply from a SATA to USB adapter.
