Hi

I was wondering if anyone can help me

i'm trying to connect with hyperterminal and im getting the error "Unable to open Com3. Please check your port settings"

any reason why im getting this? and the fix??

So i rebooted my computer and powered it down and still getting the com error.

when i check my device manager it says its a prolific USB to Serial Com Port (com3)

....

what do i do??

help please..

Also, occasionally i'll be able to connect but when i hit ctrl-z nothing comes up

...not much to go on, is it? :unsure:

I don't know what kind of system you're using, what OS, what USB-RS232 adapter,

what driver(s) you're using, whether the COM-port is (potentially) in use by

another application, what other processes are also running, what your technical

knowlegde is, ... :no:

The only thing I do know is that your PC is not able to "Open COM 3", which is

just as vague as saying that the engine of your car isn't running and you're

asking the guy of the garage over the phone why... :}

We need a bit more information to go on. :whistle:

Greetz,

Peter.

Im running windows 7

Im using a ca-42 cable

the drivers installed are prolific usb to serial

there doesnt seem to be any software running that may interfere with the com port

Ah... that dreadful CA-42 cable again :wacko:

Like already mentioned a couple of times in this thread, we can't offer

any real help when using this type of cable, since there are a lot of

different (clone) manufacturers out there, all using their own way of

doing things and each with their own shortcomings, opposed to a "Real"

Nokia CA-42 cable.

Some do need an external (3V) power supply, some don't, while others are

only able to communicate at 9600 Baud (which is too slow for our use). :unsure:

Unless you're at least a bit knowledgable in electronics, there's no easy

and fool-proof answer to give when using it.

Please have a look at this READ_ME_FIRST-thread,

under "10. CONVERTORS (or Data Cables)":

Data cable (typically Nokia CA-42):

This is deprecated.

Not because it won't work, but due to the fact that there are so many different versions of these cables, both "original" and "cheap/fakes" that it may be difficult to find the "right" connections, expecially for a newbie.

I suggest you either seek help from someone with electronics knowlegde or get

yourself a device that is guaranteed to work, even for the less experienced.

There are a few pointers in this thread of people that have debricked their

drive successfully with a ready made and easilly obtainable device.

Don't forget this is "Higher level" electronics we're talking about here, which

can't be compared to things like replacing a light-bulb or installing a TV. :no:

Greetz,

Peter.

Google for a USB to TTL converter and get one. Worked perfect for me.

I also tried my luck with this cable but it was a total waste of time as i got a fake/clone.

sorry to ask just be alot easier

Easier for who? :huh:

I don't know all possible solutions from the top of my head, I just

built a RS232 <-> TTL convertor myself on a piece of Veroboard with

a MAX232, so I could use my on-board COM-port, to de-brick my drive. :)

I don't expect others to (be able to) do the same, but the least you

could do is doing some work (and research) yourself, like using Google

as Salami suggested or scroll back a few pages in this thread. :whistle:

As a last resort you could also ask around here for people that live

in your neighbourhood and successfully debricked a drive in the past;

I'm sure a sixpack of beer would do wonders... :rolleyes:

Greetz,

Just wanted to add my thanks to Gradius2 for this. It did take a few attempts and I wasn't able to get the fix to work by wedging the card/paper in between the PCB and the HDD so removed it completely and it worked!!! Was a bit nervous throughout but it worked, FW update done and 1TB back and looking fabulous!!!

Thanks again people!!

Now that I've fixed my drive, I'm looking for the firmware update. The drive came out of a Lacie, so Seagate says they won't help me (ridiculous). Lacie hasn't responded yet.

Does anyone have the firmware update for my drive? Its information: ST3500620AS, firmware LC11.

I would greatly appreciate getting a copy of this so I don't have to deal with either company's customer service.

So you also have the ST3500620AS, and you managed to get it working with this fix. This gives me hope.

I today received a Pololu 23201a Serial Adapter that seems to be a nice choice, for this fix. I am slowing working up, soldering,

connecting to have a go at it. :wacko:

Tell you later how it works out. :unsure:

Great to hear another success-story, blackbelt007! :thumbup

Please remember that doing a firmware update might not solve the actual problem, and

you should preferably just swap the drive now while it's still under warranty.

I today received a Pololu 23201a Serial Adapter that seems to be a nice choice,

That looks like a good choice indeed and you will certainly be able to "Talk" to the drive

using it, however don't forget to externally supply power to this board between the VCC-

and GND-lines :yes:

So you also have the ST3500620AS, and you managed to get it working with this fix. This gives me hope.

Since your drive has a somewhat different firmware-version, the given procedure here

*might* not work, so be carefull :rolleyes:

Tell you later how it works out. :unsure:

Please keep us updated! :hello:

Hello Guys...i have some question`s about the "power" thing.

Do i have to connect the PCB with the battery AND put a SATA-power cable on the HDD or is the battery enough ?

And in case off only using the battery ... does the powering off and on thing means that i just have to disconnect the battery for about 10secs and then put in on again ?

Hi Zosch,

First of all I suggest you thoroughly read the instructions, since I'm under

the impression you've only picked up some highlights from the procedure and

are getting things messed up :unsure:

  • Not all solutions need an external battery; an external battery is only needed to
    power the RS-232 <=> TTL convertor, if applicable.
    Tell us what convertor you'll be using and we can supply you with the correct answer.
  • While performing the debricking you need to supply power using the SATA-power
    port using a normal PC-power supply (ie. +12V, +5V and GROUND).

Greetz,

Peter.

I'm not quite sure what you mean, I'm going to follow the guide and it has 4 wires going from the board to the PCB of

the 7200.11, and it's also using a normal molex HDD-power connector.

But this with power between Vcc and GND. :wacko::unsure: Hmm..

Dear all

Could anyone kindly tell me what is different between setup the LAB size through the "Seatool 2.20" and use CA-42 cable?

thank you

Hello all,

A just wanted to drop a note that since I could not update the firmware of my drive (fujitsu siemens OEM) after revocery in January, the drive failed again with boot of death within 4-5 months.

I just folloew the same procedure as last time to recover it again. Now, that I have sufficient resources backup the whole drive I might try potential destructive fimrware reprogramming methods, if I find tim to play around.

@PC995 If you do not write a diploma work, what is the question good for?

If seatool works, don't mess around with serial communication.

If your drive is looked unlock it with serial communication and make whatever you want in addition with official tools via SATA.

The serial connection is for serive purpose. If you do not exactly know what you are doing (and you question impliees this) you can screw up your drive easily.

Regards

Chilli
