Help with seagate terminal

[Nick_CT]

Hi all,

I'm trying to get the terminal output from this drive but all I'm getting in hyperterminal is garbage. It's a Seagate 7200.9 ST3160812AS

The drive was previously dead (faulty PCB), after a donor PCB and ROM swap the drive spins up but clicks. Probably heads or something similar but I want to know why I'm not getting anything meaningful from the terminal. If for example the heads are dead, will the terminal out be similar to what I'm getting?

I've tried the following settings and many more with no luck.
bitrate: 38400bps
data bits: 8
parity: N
stop bits: 1
flow control: off

Incorrect baud rate

I've tried 38400 as suggested, and the following:

1200
2400
9600
19200
57600
115200

No luck...

One of the things you have posted should have worked.

test and test again

Default initial BR is 9600 on this drive.

Thanks for the info. Tried again with 9600 BR and still getting garbage as displayed in the pic below.
Getting close to tossing this drive. Any other ideas on how to get something useful out of the terminal?

Hi, There are a few things you can do and check......
Are you sure the setup is good? You could test it with another Seagate drive.
I would carefully inspect the connections between your ttl interface and the drive connector. A bad contact can cause the result you are seeing. I have had this happen to me!

If you are happy with your setup then reboot the pc and leave the power to the drive disconnected.
Open your terminal.
If required power on the interface.
If required open the port.
Carefully plug in the power connector to the drive.

Terminal should now display info about your drive.

If you have set the baud rate to 9600 (which is the correct default BPS for pre .11 seagate drives) then there is likely either:

rx tx are not correctly attached/ on the wrong pins


there is something up with the adapter


Double check those things first!

I've finally had a chance to get back to this. Thanks for the info, indeed there was a problem with my serial connection. I've got a USB to serial ttl adapter. I'd being trying it on my Win7 x64 desktop and was having all the problems mentioned above. Tried another Seagate drive and got the same garbage.

Thought I'd try the adapter on my Win7 x32 laptop and bingo, worked like a charm. Maybe the driver wasn't 100% or if just doesn't like x64. Anyway here is the output the Seagate 7200.9 ST3160812AS is giving me. It sounds like the heads are dead just by listening to the drive, does this confirm the suspicion?

This output is a good indication of a head issue on this one. I would start by looking inside and then trying to find a donor drive. I have seen some that had head crashes on it and before I would get a donor to swap out heads look to see the inside of this drive first. You can examine the heads under microscope to see them better.

The main head looks fine there is problem with head 1 you can reuse the drive by disabling head 1 but for recovering data u need to change heads .
