The Solution for Seagate 7200.11 HDDs

[PDogg]

@nino do you mean the "tube" around the blue cable? like at the pic

@klingklang

is this the correct setting for my cable? I have numbers at the "cable board" 1 2 3 4. So can I be shure they are equal to the numbers at the picture?

Okey i have done everypart in the guide succsesful but when it comes to:

"Power OFF/ON the drive (very important!)

Wait 10 seconds and now Power ON your drive.

Press CTRL+Z on terminal and type:"

The terminal wont let me type after i pressed CTRL-Z. What can be wrong? I am still connected.

*edit*

Okey this is unbelievable. I successfully restored my harddrive!! Something made my cable disconnect and loose all my drivers to the cable when i disconnected the power from the harddrive in "Wait 10 seconds and now Power ON your drive". I reinstalled the drivers from this page: http://www.the-stickman.com/files/irda-ma6...ivers-Dynex.zip and went to hyper terminal again. I tried to connect and it connected but i couldn't type anything. After a little research i tried to change the com port on hyper terminal to the same as the one that was given by Windows. I tried CTRL+Z again and it worked! I just resumed with the "m0,2,2,,,,,22"- command and pressed enter. Then i got the successful format message and replugged the harddrive to the computer and rebooted. And it worked.

I am so happy i didn't think i would made this but i did it, and i am so glad. I want to thank everyone on this forum that are charing all you thoughts and infos. And i want to thank Nitrohelix that made this video that made everything so simple: http://www.youtube.com/watch?v=29FztWJVxbM

Thank you

Hm. I powered down for sixty seconds. Don't know if that makes a difference.

ABSOLUTELY NOT!

That is the schematics for ANOTHER adapter!

We have NO way from a distance to know which is which.

You need to find it yourself, by using a multimeter and experimenting (or, as SEVERAL times advised to less-than-fully-knowledgeable people, buy a "real" TTL adapter, with KNOWN pinout).

The only one that is obvious from the picture you posted is that the black wire (that goes to number 5 ) is the GROUND.

Check the FIRST image here:

http://www.msfn.org/board/index.php?s=&amp...st&p=881965

Open the "other end" of the cable.

Check that Pin1 in the picture is connected to the black wire (and to number 5 on the board).

Check that possibly Pin5 in the picture is maybe connected to green wire (and to number 1).

...and so on.

The Chip is a prolific PL-2303-HX, here is the datasheet/pinout:

http://www.stkaiser.de/anleitung/files/PL2303.pdf

verify with that pinout.

Hi every one, I'm new here, hope I'm posting in the right place. I have a seagate hard drive, Barracuda 7200.11 500Gb ST3500820AS Firmware SD25, in an external box of Iomega, connected via USB. A few days ago after a power down and on again, the windows xp couldn't recognise the partition on disk, giving me an unformated local disk. But if I disconnect the USB cable and reconnect it again, nothing comes up, it is if there is nothing connected. My question here is, is it possible that my drive has this 0 LBA error or a BSY error? Or, how can I know it? I have updated the Firmware to SD1A, but it stayed the same. I'm still waiting for my RS232 to TTL converter to arrive, but I'm not sure if I can effectively apply this solution.

I have lost 500gb of data, any reply would be helpful. Thanks

I contacted Seagate and they told me to send the drive in for a replacement, but I don't care about the drive, but only recovering the data.

I have the CA-70 Bluestar instead of the CA-42. I would also repair the hard drive?? Thanks

It was my false checked it when I had read the post again. If someone have the same cable from Bluestar (Bluestar.pl) The setup is:

black GND, white RX, blue TX. At the first time I made a misstake and connected TX with TX and RX with RX (because I thought white is TX an blue RX). But it was ok. It destroyed nothing (only Hyperterminal wasn't able to communicate with the HDD).

I fixed it with a ca-42 Cable annd a sheet of paper

So many thanks to Gradius 2, my77stang (overclock.net forum), the youtube guy (http://www.youtube.com/watch?v=29FztWJVxbM&feature=PlayList&p=B2DFC95751AC2830) and the other helpers :-)

To pffacf:

If your drive is not recognized in the bios, then it is in BSY mode.

If your drive is 0mb in bios, then it is in 0 LBA mode.

To PDogg:

Actually, the "Youtube Guy" is a girl.

If you look at the swiss army knife, its engraved with "Vanessa".

I dont want to be rude to anyone, but PLEASE use the search function or read from page 1.

Of course could we answer your questions but please try to find the answer by yourself.

Many thanks jaclaz for your prompt & clear reply concerning upgrading my SD35 firmware after recovery (your post 1971, p.99)

Seagate was not able to "help me" or should I say that they were reluctant to help ....

Thanks to all of you once again

Please can someone help me with my problem?

To Messiah24

Have you opened it?

Do you have the needed circuit inside?

have you done a pinout-check?
