The Solution for Seagate 7200.11 HDDs

Had no luck with my first try to get some help :}

Maybe this time...

Hi everybody,

I'm sinking into despair after having tried for two days to fix my Barracuda HD. I hope someone could give me some help :}

Ok, this is my HD: 1Gb, ST31000333AS, firmware LC15.

I've been able to set up the connection between the computer and the HD trough a DKU5 cable. I could complete almost all the steps suggested by Aviko, Gradius and some others, getting the expected messages (spin out, spin up...) in the hyperterminal. BUT the last one: when I write m0,2,2,,,,,22 and click enter I clearly hear the HD stops and nothing appears on the screen, no matter how long I wait.

I've tried everything I've found in this forum and nothing works (covering head, motor, both...). If I shut down the HD after N1, as stated in Gradius guide, it seems the HD returns to the busy state and when I power again the HD the hyperterminal doesn't respond.

I've read almost every page in this thread and I've found a few references to this problem of no response after m0,2,2..., but no solution.

Anyone has a clue?

Thanks

Hi,

I am having a little trouble with this fix. My HD is a Maxtor DiamondMax 22. I got all the cables made up successfully and went through to clear the BSY state initially. This seemed to work and all the outputs from Hyperterminal were as expected.

I put it back into the pc (a Dell Dimension 5100 if it matters) and it saw the drive in the bios but the capacity was 'unknown'. I figured I'd try the LBA fix, all outputs as expected, put it back in the PC and the drive was not detected by the bios again.

Ok, so went back and did the bsy fix again including the G-List step, now back in the pc and yay! Detected and found the size (500Gb). Powered down, connected all the drives in the machine, powered up and the drive was no longer detected.

Is it just the firmware problem thats stoppin it working fully or is there something I'm missing? I ended up leaving it last night as I was getting tired and didnt want to make a mistake but I'd really like to get this repaired.

Thanks for any insight.

I face a strange problem with solution (i have the busy state problem)<br /><br />When I try the loopback test (connecting RX-TX cables together) i can see what i type in the hyperterminal<br /><br />

When i connect the cable to the hard disk and try to communicate with the disk, all I get is strange characters.<br /><br />

I have tried with **38400,8,N,1,N** and also with **38400,8,N,1,Hardware** with no result

Hi,

according to description my Seagate 7200.11 is in BSY brick.

I have Siemens IP40 RS232 cable for mobile phones (which is voltage level shifter - so I've been told) and i know which wires i need to use (white is RX, yellow is TX, and black is GND) but i heard that i need somehow to power the drivers which are in RS232 connector (Vcc - the red wire in cable). Full info received from a guy who knows Siemens serial cables is following:

"the Vcc is to power up the drivers which are located in the RS232 connector of the cable. Without the power for these drivers you will not get a connection. This cable is a voltage level shifter so you have to connect the

red Vcc cable to the logic-power-supply of the harddisk (normally 5V I suppose). On the RS232 connector for the PC side you will have voltage-levels of about +/-12V which is normal for RS232 connections! Therfore there is a level-shifter-driver included in the RS232 connector which need at least the power from the target device, in your case from the hard disk."

Now, since i am not engineer I would kindly ask people to simply (electronical schemes do not mean much to me as I do not know how to read them, so please be specific and simple as much as possible) tell me how to do this (powering the cable)? My idea about powering the HD was to simply connect the drive to SATA USB external housing - but what about the power to the cable?

Many thanks for assistance :-)

I've now managed to get my drive back up and running.

Thanks to the OP for the information, saved a lot of inconvenience!

You have a problem (and either an incompetent "guy who knows Siemens serial cables " or you misunderstood him).

There is NOT any "driver" inside the connector.

There is a "converter", and IC (integrated Circuit) that takes the RS232 signals (and yes, they peak at 12 V) and converts them to TTL level.

This IC must be powered and normally it is powered by the "attached to PC" side, but some cables for cellular phones do need to be powered from the "attached to phone size".

Problem is that there are IC's that need +5V cc/0 and some that need 3÷3.3 V cc/0, some that will "like" everything.

As well, there are two different TTL levels, a +5V and a +2.8/3.3V one, and even converters that will choose which TTL level depending on the power you give them.

If you are lucky your cable is one that will like "any" power voltage and anyway output the "right" TTL level (the 2.8/3.3 one).

Read this post, where the matter is a bit more explained:

Hello everyone.

This is my first post here, even tough i have been reading all the info in this thread for the last days

Im, like many others here, desperate.

I have absolute no knowledge of electronics or something like that.

I was using my PC. Turned off.

Next morning, Barracuda HDD wasnt recognized. I can hear the spinning but thats it. BIOS no longer recongized the disc. Thats why i guess i have the "brick" mode. I have run even the soft which i previously burnt in a CD, booted with that and the HDD was not shown there also... im very afraid i have "ruined" the drive...

I have (and i fully know its my fault)all, and i mean ALL my precious and all my important info in that HDD (i bought it not many months ago). Among other stuff, i have ALL the pictures taken with my camera since i own one, including my sister´s wedding and my best friend´s wedding, all my collegue papers, info, ebooks, documents including my final thesis and stuff like that. again, i know i should have done a backup before, but thats exactly why i bought this HDD.

I have tried for the past few days with no success to connect the HDD to the USB port.

I have tested and broken 5 different CA-42 cables, with different colours and amount of cables.

With the first cables i couldnt even install the USB driver (i received an exclamation mark and the USB-URLA device not installed properly and couldnt find the **** driver over the net, even tough i tried everything including Nokia´s driver)

After buying my second batch of cables, i managed to install them properly but...i received a "COM3 port is already in use by other device". I tested that with at least 4 different COM ports with no lucks

Finally, the last cable i bought (they are not original Nokia branded but other ones very common generic (and lot cheaper) in my country (Argentina) was installed succesfully (COM3). I entered Hyperterminal. The longest i could go was i got strange characters...then, absolute nothing. Nada.

I have no idea how to identify which cables are TX and RX. Have no way of measuring, nor electronical skills. I dont even know if i have done right the job of putting the cables in some old pins i have from an old Pc cable. So i cant even be sure if the cables are actually doing any contact with the HDD pins and thats why i got nothin gfrom Hypertermina.

I have followed exactly all guides with the last details here (included the one in spanish) with no results at all.

So, i have nowhere to go. I dont know anybody here in my city (Buenos Aires) who would help me. Thats why im asking desperately help here

If anybody has already used a cable with success, i would love to buy it (i can pay a very good money since i have invaluable data on that hard drive) and im close to giving up , resigne, cry a little (or a lot, for the loss) and throw the hdd to the garbage.

Please, please, somebody help me. I am willing to pay for an already made cable/adapter/whatever who has already done its job perfectly, so i can fix my disc.

Any help/tips/hints/advices/suggestions are more than welcome, even if they are a how-to-for-dummies-like-me with pictures about what im doing wrong/what else do i need/how to know which cable is which, etc etc etc. I have no tester/multimeter or such a tool and i remotely know how to use it.

You guys are my last resource. And believe me, im very very sad, and depressed. I have vaguely slept in the last few days. Im like a zombie, all day thinking about the **** disc and blaming it, and blaming me....and buying new cables CA-42 (or DKU-5) in order to achieve this...with absolutely no success...

Please, i beg for your help

Kind Regards

Sebastian

@Nc1224

see the post below by Tracy on p. 117. Notice the picture. Look carefully at the 3 wires colored black, white, and blue. Notice that the black wire is soldered on the back of the board, this is your GRN. Look for the same position on yours. it might be a different color wire.

Likewise, notice the white is at the top right (not on the edge of the board) and the blue is at the top of the edge. Those are the 2 positions you want to look for in your CA-42 board. Again, your wire colors might be different but these two wire positions are your TX and RX wires.

btw, no need for power since this cable gets its power from the USB port. But make sure it is a powered USB port, not part of some hub!

Another HD fixed! :) A big Thank You to everybody who has contributed to this thread.

I used this CA-42 cable of ebay,

74fce464715242.gif

It has this chip inside. ( PL-2303 )

71102564715247.gif

Black = Ground, White = Rx, Blue = Tx,

Sebastian,

Rather than sending you a cable that works, let's work through your situation. Since you said that you have 5 CA-42 cables, we only need to get one of them to work. Look at the picture above of the CA-42 USB side. If you use something sharp to separate the plastic cover, you should see the wires soldered on the chip. Look for the ones that match the position of the 3 wires above. Those are the 3 wires you need. If you look carefully at the picture, you can see that the blue and white wires are near the top of the chip (the white is to the right of the blue) and the black is at the bottom. Look for the wires that correspond to those positions in your cable.

By the way, the above photos are from CA-42 cables made in china. I believe the ones made in Thailand are wrapped in some type of hard to remove plastic shrink wrap.

Take a picture of your chip once you open up the USB side and post it. We'll walk you through it.

Hi mundy

Thanks a lot for your tips

Here is my cable and a screen capture of what kind of things i see when i run Hyperterminal (i see them randomly, sometimes i connect and nothing happens. Sometimes i connect and it looks like the pic)

BTW, box is similar to the one above. My cable is from Chine but packaging is exactly the same

I hope this can be the beginning of my solution....hope the pics are good for you

You mean the side with the cables, opposite to the side with the USB port? You need a close picture, right?

no, I need a picture of the other side of the board that attached to the USB port.
