The Solution for Seagate 7200.11 HDDs

Recommended Posts

@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,

It has this chip inside. ( PL-2303 )

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

Sebastian,

can you take a picture of the other side of the cable?

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

I have already posted that pic i think....i posted 3 pics. One with the strange characters i see on the Hyperterminal..and the other 2 showing both sides of the cable in the USB port side....

Maybe you need better pics???

Gavilan,

I'm sorry I missed the 3rd photo. However, the reason why I asked you to take pictures of both sides of the USB board is b/c I cannot see what color wires are at the various solder points. In your two photos, are you sure you are taking a picture of the same board on both sides? I ask b/c in both photos, the red wire is soldered to the photo side but there are soldered to different sides and different points on the board, which cannot be since there is only 1 red wire in both photos. I hope you understand why I am unable to help you right now.

Please post a photo of both sides of the USB board of the same cable, not of different ones. They are not wired the same so you need to show me photos of the same cable but of both sides of the USB board.

Yes, i completely understood what you said

But, believe it or not, pics are actually from the same cable.

And yes, this cable was wrapped in some type of hard to remove plastic shrink wrap as you pointed out. So it was really hard to go until the usb board itself.

Im at my girl´s house now. be back in my flat in about 3 hours.

I will take in-detail pics of both sides of the cable. Maybe that will help you (and me) to try to go one step further on this.

Thanks for keeping my faith alive

:)

Great job Gradius! :thumbup

And why did the guy above quote the entire fix?! Edit:LOL

BTW Maybe you should PM the moderator to ask if this topic could also be moved to the "sticky" section.

I joined this forum, only to thank you. I found this topic by google search engine. It is very simple and

perfect indeed. I would like, please, to exchange more information. I don´t know how to contact you in this

the "humble" professionals who believe in sharing knowledge.

Thank you very much,

My best regards,

Toni
