The Solution for Seagate 7200.11 HDDs

4,868 posts in this topic

Hello everyone, first of all apologize for my English as it is translated. I have two hard disks affected by the problem of one is a seagate firmware and the other maxtor.

The models are:

Maxtor DiamonMax22 STM3500320AS FIRMWARE MX15

Seagate Barracuda ST500320AS FIRMWARE SD15

I've been reading this forum and I built a cable from data cable CA-42 USB as I reached for another COM port adapter bought on Ebay that also is this DIGITAL CONVERTER KIT CMOS / TTL TO RS232, 3V, Low Power .

What you can see here http://cgi.ebay.es/ws/eBayISAPI.dll?ViewItem&item=200360298309&ru=http%3A%2F%2Fshop.ebay.es%3A80%2F%3F_from%3DR40%26fts%3D2%26_trksid%3Dp3686.m38.l1313%26_nkw%3D200360298309%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1

I use hyperterminal xp professional and properly configured.

Remove the pcb disk and connect the Tx and Rx.

Then I feed the sata connector on the PC.

The question is that with both wires get the same result in hyperterminal

marking the beginning and is Ctrl + F3 T z>

then frame 2 and the result is this

F3 T> 2

LED: 000000CC FAddr: 0025BF67

LED: 000000CC FAddr: 0025BF67

LED: 000000CC FAddr: 0025BF67

LED: 000000CC FAddr: 0025BF67

LED: 000000CC FAddr: 0025BF67

...

Cyclically So I find no way of marking the Z because it lets me get to that point.

I have read every post I could but it's the 2 weeks I am with this and now I can only ask you.

Does anyone of you have or have turned this problem?.

Thanks for your help.

Saludos

try to update the firmware

the bios does not recognize me the disks, I'll try anyway. Thanks

Since the firmware is stored on the drive itself (the platters), I wonder

if you even could be able to do an update... :unsure:

I got a message like this in my attempt when I failed to wait until the hdd has stopped spinning at the very beginning. For me, when I first plug in the hdd, it would power up and start spinning. After about 3-5 seconds, it would stop spinning. Then I would start the hyperterminal and go through the process. If I started it before it stopped spinning, I'd get this error message. So try that.

You will not be successful at updating the firmware in this state.

tried and nothing. continues the same. I turn the HD on, wait to the engine to start spinning, unscrew the screw and then lift up and put a separator. It stops, I try to connect with hyperterminal. Same failure.

...and that's what you're doing wrong. :hello:

Since the firmware is stored on the platters, once you apply power to the drive the firmware

is loaded (and fails), resulting in a busy state.

The trick is to only access the controler, before it is even able to load the firmware and

this is done by temporary disabling the drive motor (by separating it from the PCB).

Now you will be able to access the controler (and it only *thinks* the drive is spun up),

so you have to let it *think* the motor is not spinning again, by invoking the spin-down

command.

After that you can re-seat the PCB (remove the separator) and spin the motor up again.

So the correct order is:

  • Remove PCB (or put something between the drive's motor-contacts)
  • Apply the COM-connection
  • Apply power to drive
  • Spin down motor (it actually wasn't spinning in the first place)
  • Re-attach PCB (or remove motor-contacts spacer)
  • Spin up motor (now it will really spin up)
  • Perform commands to get drive out of the BSY state
  • Remove power and COM-connection to drive
  • Connect drive to SATA-port on PC
  • Power up PC
    • See if it recognises it as a drive
    • Check if the drive is not seen as a 0GB drive

If the drive is seen as a 0GB drive, you'll have to perform the additional LBA0-steps.

When the drive is working again: make a backup of your drive ASAP followed by a thourough

test using SeaTools for DOS.

Greetz,

Peter.

+1 with Peter. You are doing it backwards and that is why you are getting the error messages. As Peter said, you need to put in the separator, screw in the 3 torx screws on the other side and then plug in the sata power. You need to follow the tutorial exactly in its proper order. You cannot mess with things and expect it to work properly. hope you get it working.

I believe my steps are correct, please correct me if I'm wrong.

These are my steps:

1 - Remove or separator in the top 3 contacts the controller.

2 - connect rx, tx and mass

3 - connect SATA power

4 - open hyperterminal

5 - Configure Connection COM10, 38400, 8, nothing, 1, none

6 - Ctrl + z

7-T responds F3>

8-type 2

9 And from that step always responds

LED: 000000CC FAddr: 0025BF67

LED: 000000CC FAddr: 0025BF67

Greetings and thanks for the help.

Hmmm, indeed the steps look alright (I guess you only mixed up the order when posting).

Luckily I saved my log of HyperTerminal when unbricking my drive and this is what it looked like:

  • Disconnected PCB from drive
  • Connected COM-convertor and
  • Applied power to PCB:
    LED:000000CC FAddr:0024A051LED:000000CC FAddr:0024A051F3 T>/2
    F3 2>Z
    Spin Down CompleteElapsed Time 0.146 msecs
  • With the power still applied to the PCB, I attached the PCB back onto the drive.
  • Spin up motor again:
    F3 2>U
    Spin Up CompleteElapsed Time 6.824 secsF3 2>/1
    F3 1>N1
    F3 1>F3 T>m0,2,2,,,,,22Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = 00C8
    User Partition Format Successful - Elapsed Time 0 mins 00 secs
    F3 T>
  • After this, I could access my drive again (over SATA)

As can be seen, my error-message at the beginning was different.

Mine:

LED:000000CC FAddr:0024A051

Yours:

LED: 000000CC FAddr: 0025BF67

So... that might be the problem in your case? :unsure:

These are my steps:

[...]

7-T responds F3>

8-type 2

The fact your PCB responds to CTRL+Z is a good thing, but to enter Level 2 diagnostics you'll have to press:

/2

(Slash 2) not just

2

:huh:

Are you sure you've typed the slash ("/") before the "2"? :unsure:

Greetz,

Peter.

I would reiterate that there are two "school of thoughts", one that insulates Head contacts and the other one that insulates motor contacts.

If with one set of contacts don't work, use the other one.

To be honest: I only followed the initial roadmap by Gradius2 and entirely

removed the PCB from the drive (so both heads, actuator as platter-motor

contacts were isolated), but you'll have to make sure when re-fixing the PCB,

you don't short circuit anything (and fry it)! :wacko:

I just did it for peace of mind: I didn't like the idea the heads would move

over the non-rotating platters at drive startup.

(FYI: the heads hover over the platters by the thin layer of air that is

generated by its rotational force)

Greetz,

Peter.

Thank you!!

It worked for me!

IMHO, WRONG. :(

Correct sequence:

  • Backup the most important data on the drive
  • Verify that the backup is functional contains everything of value to you
  • Find a way to have the drive swapped anyway

Let the guys at Seagate take the responsibility of re-certifying the (existing) drive or giving you a refurbished one.
