Seagate Bricked Firmware Drive Fix (With Pics) - Page 15

post #141 of 279
Success! Thank you to almost everyone on this thread, but wrench in particular for his PMs guiding me through the process, which I will post below for others who are having trouble:

-Nokia CA-42 cable, Made in China, but dark blue ends
-9-pin Female D-Sub Connector from RadioShack (~$1.99, part #276-1428) for its pins (I used 6 of the 9 because I messed up a few times, but you only need 3)
-Heat Shrink from Radio Shack (~$3.49, 1" tubes)
-Wire Strippers (or small scissors and LOTS of prior experience stripping wires)
-Possibly a tiny knife (such as one found on a Swiss Army Knife)
-Drivers (http://www.usglobalsat.com/download/546/win_drivers.zip)

I obtained a CA-42 cable from eBay seller "gadgettown" because it was the cheapest and closest to me of the US sellers. Furthermore, I inquired if their cable was made in China and they stated that it was (for other US sellers whose CA-42 cables are of Chinese origin, see two posts above). Also, wrench confirmed this information in a PM as well since he purchased the item from the same seller.

I cut off the entire Nokia phone end, I stripped down the insulation about two inches with Swiss army knife scissors (no wire strippers at home), and then I VERY CAREFULLY did the same for the individual wires. The small wires are so small and fragile that you can literally just strip the insulation with your fingernails after a tiny incision with a Swiss army knife-sized scissors/blade.

There were five wires - I got the same cable as Dia's (find his post a few pages back) - and so I snapped open the USB end with the Swiss army knife to see exactly what wires were soldered where: green and orange ones aren't soldered, black is GND, blue is RX (connects to TX on HDD), and white is TX (connects to RX on HDD).

I VERY TIGHTLY placed the pins from the D-Sub connector to the ends of the blue, white, and black wires with pliers. I made sure the wires did not easily pull out of the pins, which caused me problems once during operation of the terminal (so I had to redo the entire thing).

I used a Bic SureStart lighter to carefully shrink the heat shrink on the appropriate wires - maybe 1 to 2 seconds per wire is all that is needed. Don't over-shrink the ends that go into the HDD because if they are thick and snug they won't move/fall out of the HDD, which works out in your favor very well.

I connect the wires to the appropriate pins on the device - thanks to the heat shrink they fit very snugly - and did the LBA=0 fix (CTRL-Z, wait for F3 T> prompt, then the "m2" command) because my drive was detected as a 0MB drive (if you are doing BSY you need to do the whole business card thing with all the other preliminary steps).

It took 45 to 60 seconds for the terminal to report "Partition format success" or whatever the message is (the same in the original post minus the second line) and then I restarted my PC and I was good to go.

I would recommend that you start a new thread as this one is dealing with a very specific problem and solution. You are asking for diagnostic questions which is really not the point of this thread.

I'd like to add a few useful notes. I found this when I tried to figure out the right wires to connect:

If you're using a german keyboard (QWERTZ-Layout) and Ctrl+Z doesn't work, try Ctrl+Y before switching RX/TX.

Also you can figure out RX and TX quite easily: Connect two wires and type something on the console. If it does echo, you hit the right ones! Now you have to check which one is RX and which TX.

Thanks to the previous posters for their useful intructions.

WOW Guys, this is my first post, and this post is a great big thank you for all your help.
Without this post my life would of been a 1TB misery of disaster, and my seagate 7200.11 LC11 went down, and thanks to 'Ezygroove' who is my hero.

My data is now successfully recovered and i'm on the hunt for a bigger and better drive. RAID 2TB probably.

One thing i will say, is that if you are having problems like this but you manage to just get the drive recognised by the machine then try using Data Rescue 3, somehow a full scan didnt work but a quick scan found my original directories and file structure.

again, thanks for everyones help

I have a 1.5tb seagate that spins up but isnt seen by windows. I have tried the nokia cable route using a few different cables to no success. I just got a RS232-to-TTL board and followed instructions I found on the net. I have the RS232-to-TTL board working with a loop back as a test. I have the cables hooked up right as the recieve light on the board lights up but I can get no response from hyper terminal unless I jump the tx and rx pins. I have everything hooked up it seems. I power on the drive and RS232-to-TTL board then launch a hyper terminal session with 38400 8 n 1 config but I get nothing on the screen. I tried swapping the wires on the drives pins...the rx and tx but nothing happens. This seems a pretty easy deal to do but I cant get the drive talking to hyper terminal. I have searched and read TONS of instructions on this.

Anyone have any hints on what I am doing wrong? I have lots of financial stuff on this drive so dont want to send it to seagate if I can get around it and fix it myself.

thank you in advance for any advice!

What is the firmware on your hdd? My initial guess would be that you are dealing with a different problem especially yours is a 5900 rpm where most of the problems have been with 7200 rpm.
