Drive is busy example, not solution: drive ST3500320AS SD15
remove 3 screws nearest heads connector, motor connected, put something between pcb and hda to lift pcb and prevent contact.
power on, wait until drive stops motor, if you dont wait at this moment you got 000000CE error after next command

this part is not necessary, just checking is everything ok, use when first try fails (F712 work only on 500g 7200.11 with firmware SD15, when you updated f/w just skip this partF3 2>/

(finished, power off, connect disk to pc and check your data)
when, finally, my HD will communicate with HyTerm I think I will follow the instruction above... but is all that sequence does with something between pcb and hda?

Thank you, very kind!
Now I know my new chinese cable is not working! :realmad:
hello Magic
look at the photos in my previous post directly connect the interface TTL to the com port.
thanks Tristano...

another question on CA-42.
Once the driver installed is there always 3V on tx/rx or only when HTerminal and connection is on?
Someone could test it for me?
Thanks.

I've colored the important parts in red...please help me!
When start communication with Hyperterminal it starts to type random characters and my keyboard is disabled...
I have used a ca42 pin 6/7 to TX RX, is it wrong? Do I short my cable?
Tokuro, you're right too.3.3v is already in RX/GND and TX/GND. With a little help of a volt meter you can find the ground: connecting the negative pole to the ground wire and the positive to RX or TX you will see that 3.3 voltage in the meter. Once you set up your terminal session, by typing some random chars in the terminal you'll see in the meter that voltage slighty go up or down in the TX line, the other one should stay fixed on 3.3v. With this you can find RX and TX wire too and then you're done, connect TX and RX to the HD and if you don't share a common ground (if you use your notebook for the usb plug and another PSU for powering the HD) connect the ground wire on the HD pin 2 as showed on one of my previous posts.
My cable had 6 wires and the right ones were white (GND), yellow (TX) and blue (RX) but sadly there're no standard colors.
If you don't have a volt meter, you can also do a very rough test. Set up your terminal session and slightly let touch 2 wires at once. If you see come up strange characters in your terminal window, then you have in your hands RX and GND wires. Then, type random characters in your terminal and do the same with the other wire and when you'll see what you type come back in your terminal window it just means you connected RX and TX togheter (a loopback connection!!).
Do some trial and error and don't be hurry! Good luck!
Before I chop its head off... anyone knows if this cable should work or not????It's a CA-45 Nokia Cable. Pictures attached.
It's the same -nameless- brand i bought! The only thing is that mine was CA-42, this is CA-45. I cannot be sure, but I think the only difference is in the phone plug model, the long usb connector seems to be the same as mine. Inside it there's a chinese USB to Serial Arkmicron chip. Note that for those chips there're no Vista drivers, XP only.
You may also check on pinouts.ru website for be sure it has TX/RX/3.3v.
Well, I've just chopped it off. And it has 3 cables: Black, Red and White.
You were right: it installs as "Arkmicro USB to SERIAL" in my XP notebook.
You were also right: my vista PC won't install it. (no drivers)
You were right too: It is a long USB connector identical as the one seen in the CA-42 and DKU-5 pictures on the net.
But... are you sure I've to check if one of the 3 cables is 3.3V???? I was assuming that the 3 cables were for TX, RX and GROUND. Am I wrong???
Greets, ToKuRo.
I guess you are using RX and GROUND instead of TX. If you are SURE that you have TX and RX then you should check if your cables are not short circuiting. (<--not sure if it is the right word)
Greetings.
oh oh... I have tested my CA 42 and doesn't have 3,3V in TX or RX! :realmad: :realmad:

I have tried to connect with hyperteminal but i get it once... below now is always in automatic mode :-(
Another question:
It's better to power off when invert tx rx?

I'm now waiting for the delievery of a ca-42 cable.
I've got a st31000340AS and fw SD15.
Is it better to upgrade quickly to SD1A if I can reanimate the drive?

just tried with
CA42_RX->HDD_TX
CA42_TX->HDD_RX
pin near HDD_TX ->GND of PSU
Nothing changed.
A lot random charachters when connected with hyper terminal.
At now I don't have tried with another converter because it's hard to found it.
Internet, ebay my last chances :-(
