The Solution for Seagate 7200.11 HDDs

Recommended Posts

Thanks to Seagate's utter incompetence and willingness to disregard their customers, I find myself here after finding my ST3500320AS is now completely bricked.

I have studied this thread as thoroughly as I think I need to complete the fix, although with minimal electronics knowledge I have one main question. I am going to use the CA-42 cabling method as I have a few on hand that seem to be in working order, but my question comes in regards to the connection between the cable wires and the PCB. I have no soldering equipment so anything to do with that is not an option, are there some sort of jumpers I can purchase that will fit the PCB connection? What would the consequence be if the RX-TX wires accidently shorted during the terminal session?

If someone could provide close up pictures of their cable wire to PCB connections it would be much appreciated. Are there any hints or tricks without the need of a soldering iron? I don't want the connections to drop out midway through the terminal session or at any stage of the process to be honest. Cheers in advance for anyone who provide help :)

No problem if you short TX-RX, you will simply do a "loopback" test. :)

There are several detailed view of the connections in the thread, take your time on it and you will find them.

Best, without a soldering iron, is to use some copper wire non-flexible, typically telephone cables (not the ones from the phone to the wall outlet, the ones from the wall outlet onwards) or network cables are good.

You simply get a nail, slightly smaller in diameter than the HD pins and wrap a piexe of the naked cable around it in a TIGHT spiral.

You will see how you can easily slip it off the nail (or pin) if turning it in one direction and how steady it is if you try turning it in the other direction o simply try to pull it off.

Then you simply intertwine the other end of the piece of cable with the wire coming off the converter and wrap it in insulating tape.

The technique is called "wirewrap" and is was commonly used in telephone PBX's and the like:

http://en.wikipedia.org/wiki/Wire_wrap

If you want to create your own "poorman's" wire wrapper tool, all you need is a small metal tube (Hint: the needle of a big syringe - like those sometimes used to apply lubricants or compounds) with a cut notch on one side will do.

Hello,

I'm new here, this is a great thread but I have a problem, I have done exactly what has been said on here regarding unbricking my seagate drive, however when I come to switch off the power then switch back on, I cannot talkle to the drive via Hyperterminal, I can only talk if I unplug my drive a second time, then of course the commands don't work.

I'm using a computer with xp, a nokia CA-42 data cable so using the right stuff, don't know what is the matter.

Has anyone else had this problem?

You're the 2nd person in recent days to say the exact same thing. I have 2 questions.

1. How are you powering your sata hdd? Using your old computer?

2. Are you making sure that it is sharing the same ground?

When I did it, I was using a the desktop with a different hdd and the CA-42 cable. They were sharing the same ground.

but when i reboot my computer...bios is "locked" and cant find my Seagate...

The HyperTerminal-log in the pic looks fine to me... :unsure:

But... It can be that the SATA-interface is defective as well, like I had.

After my Seagate bricked itself (connected to my mobo's VIA controler) and I tried

to connect another (working) drive instead, on that same controler, it wasn't seen

and the BIOS hanged (until a timeout) while searching for attached devices.

At first I thought only my controler was defective, but I soon found out that both

my drive as the controler were dead :blink:

Luckilly my Asus K8V SE Deluxe motherboard also has an extra promise SATA controler,

so I was able to use that one instead... :thumbup

Like Mundy says...

If you ever plan to experiment/work with harddrives, you should at least get yourself

an USB-to-(S)ATA adapter; these cheap devices are really they're money's worth :yes:

When you use such an interface:

  • You don't have to reboot your computer everytime you want to test things out
  • The drive is powered externally, so you don't need to use the (short) power
    leads from your PC's power supply and you can apply power to the drive when you
    wish (you don't have to power down your PC).
    (You do have to make sure though, that the ground-signal of both drive as RS232-
    interface are connected if only the RS232 connection is used).
  • It's just a nifty little tool to quickly diagnose (S)ATA devices without opening
    (or possibly destructing) your computer

Greetz,

Peter.

Hi,

I am using a proper external power pack coupled upto the drive, a Nokia CA-42 cable to connect drive to the computer (a laptop) the three pins on the drive are all connected via the CA-42. I have also tried using a cmos/ttl serial port via a USB connection and that had the same trouble. I don't know what I'm dong wrong.

Ian

Hi there,

Just received this USB-TTL adapter: Adapter Link

Unfortunately, when I connect this adapter to my computer the computer makes no indication that anything has been connected (no popup in the taskbar and the device manager doesn't refresh or display any new devices). I have tried this on two different computers and I've plugged the adapter in with and without VCC connected to GND.

Any suggestions?

Hello,

I'm having problems with my Touchsmart PC I can't boot it up since it can't find the C drive. My PC has a Seagate 7200.11. Does this fix work in a HP Touchsmart PC?

If your PC has the faulty model and firmware, then yes, you will also have this problem. You can take the serial number of your seagate hdd and go to the seagate website and type in the serial number.

go here http://seagate.custkb.com/seagate/crm/selfservice/search.jsp?DocId=207931&NewLang=en

and choose #2 "click here to use the serial number check utility"

it will tell you if it is one of the affected models. that is the sure way to know if it is this problem. btw, it doesn't matter the brand of your pc, if they used the faulty seagate hdd, then you will have this problem.

Great job, Simba, that might be usefull for other members with your

type of drive/firmware :thumbup

Although I would like to emphasize that playing with the command-line

options of the firmware-updater is at the user's own risk.

Flashing a drive with incorrect/incompatible firmware will kill it.

Greetz,

Peter.

This is true, but the drive came from an Iomega enclosure. The model numbers matched, but because it was an LC firmware (not SD), it wouldn't flash. So, I had to force it.

It's been a couple weeks and haven't bumped into any issues.

So don't we (to use Jaclaz' famous words: "I have my crystal ball at the shop for a retune") :whistle:

First make sure you've got a properly working TTL-RS232 connection before doing anything else.

  • Install the interface's (USB) drivers.
  • Check that a loopback-test can be performed at (at least) 38400 baud
    (Remember that not all CA-42 adapters are created equal; see other posts in this thread)

Once you've got that working, come back here and describe exactly what you've tried and done.

Unfortunately, when I connect this adapter to my computer the computer makes no indication that anything has been connected

Like most (if not all) USB-devices, you first have to install the drivers before you plug it in.

(Though Windows *should* respond and detect an "Unknown Device" once you've attached it) :unsure:

Possibility 2:

You *could* have received a DOA (Dead On Arrival), if so return the interface for a replacement.

Greetz,

Peter.

Hi,

I can communicate with the drive, so I think the connection is correct, I can enter commands into hyperterminal ok unitl it comes to switching off the power at the HDD, once I connect it again I cannot enter anything into hyperterminal,(i've tried ctrl-z) the only way I can do that is by disconnecting the HDD power source again, but when I do that I can enter commands again but the process has been interupted and won't work

The CA-42 cable is connected to a laptop via a USB connection, I have got a connection on all the three prongs that are used on the HDD (gnd, tx,rx) and I am using a external power supply like the picture in videoripper's post.

I don't know what else I can try.

Regards

Ian
