The full version (pay) is compiled and locked on the Pc where it will run.

I solved my problem with momentus password and can help you.
Read vendor and give it to me.



Free SeDiv can read but can't write. If HyperTerminal can connect to hdd, free SeDiv must connect too. Check Com Port and Baudrate and other options. I can success connect with Baudrate=9600, Data bits=8, Parity=None, Stop bits=1.
1. Press connect
2. hdd power on
3. See connection log and press CTRL-Z

Sorry for the off topic.
Yes it must show you the terminal log. Drive have to be connected and then you must press "connect".
Then you'll see the terminal. Maybe you should press CTRL+Z to see the T>
Anyway it need terminal connector for seagate.
Soon new version will be available, that will work with WD too.
I will write a review soon.
The full version is not free and you have to contact the author!
