I think the baud should be 38,400

RX/TX signals on Seagate hard drives:

3. Open up the terminal window, select the port number and speed (for Seagate 7200.10 and older: 9600; for 7200.11 and newer: 38400);

The "[10]24k" would suggest that the baud rate is correct. Other than verifying the parity and start/stop bit settings, I would measure the voltage levels on both sides of the TTL interface. I would also confirm the grounding.

Yes, and the "Mas" is the start of the "Master" output from a healthy drive of this type.

Hello,

Problem SOLVED. It was problem with grounding, like Mr. Zabkar mentioned.
I connect ground directly to HDD.

HaQue, thank you for your baud rate suggestion. For this model is 9600

Thank you Mr. Zabkar, HaQue and PCImage for your replays and support
