Seagate Bricked Firmware Drive Fix (With Pics) - Page 20

post #191 of 279
Hi, first , thank you for all posts relating the seagate problem.
I have one qestion: Has anibody used a serial DAU-9P data cable to do the job?
http://yournokia.free.fr/nokia/cable.php3
If yes, pls some help with drivers needed , hiperterminal and port configuration if possible
I've used the dku-5 configuration parameters for the com port
The only answer from the HDD in hyperterminal, when i send the ctrl-z command is an arrow to the right , if i send some characters "A" in hiperterminal i see oval faces....mad.gif
Any Help appreciated ....

Where can I get those square gold connectors from? I checked radioshack and they don't sell it. Where else would I be able to pick them up? I need them to connect the cable to the serial port on the drive.

I just want to say this is complete GENIUS. I never knew what those four pins were for on an HD, but now I know they're an undocumented firmware communication interface. biggrin.gif

Has anyone worked out the available command set information?

Also, why do you need to lift the PCB off the HD when you unbrick it? I'm curious about that bit.

Maybe to override some kind of protection?

Or it's to prevent access to the actual drive heads. That would prevent damage to the data on the drive.

I am using TTL to RS232 converter i've problem coming to the command. any suggestions?. i've attached the pic with description .404

Please I need some help! Just one little step and I'll succeed.

I've got everything working....cable, wires, driver, hyperterminal.
But when I put down the power for a few seconds before going further to step 13 hyperterminal STOPS or breaks the connection!!!
And I have to start over from step 4. How can you put the power down without breaking the connection with hyperterminal?

I don't read anything about this problem.

before you type the command m22,0,0,0,0,22 you need to disconnect power and reconnect.. wait about 10-20 seconds then enter that command or else it will not work.
***edit***

Step 13: Type m0,2,2,0,0,0,0,22 and press enter. (Note the "m" is lower case and the 0's are zeros). It should say.....

Well, I decided to use an actual serial cable, hooked up to an actual serial port instead of a USB to serial interface, and NADA. 2X checked the cable wiring, even tried reversing the TX and RX. Nothing. 2X checked the com port configuration. Nothing. I get nothing back from the drive. With or without a card separating the head contact from the PCB. What is going on?

Hi,

I got a Maxtor DiamondMax 22, STM3500320AS with firmeware MX15.

I try to connect by a serial cable to a serial port of the computer. I dont habe a nokia usb cable.
When i try to connect like its told in the how to, nothing happens. Crtl+z and Crtl+y (i use a german keyboard layout) are not working.
When i remove the paper witch covers the data ports of the pcb and connects the power cord again, the console returns some hieroglyphics frown.gif
I double checked the correct baud rate. But i think this could be a problem.

When i switch the Tx and de Rx pins i get not return from the console.

Can someone help me?
(sorry about the bad english, iam from germany wink.gif )

Greetings
