    The Solution for Seagate 7200.11 HDDs

    in Hard Drive and Removable Media

    Posted

    I have a hard drive exhibiting signs of the BSY error. When I connect my interface to the drive I get: (see attached)

    Any ideas?

    Thank you.

    I have got the same problem connected with a bulky CA-42 cable.

    Tomorrow I hope to find a RS232 to TTL and i will retry...

    :ph34r:

    how many wires did u connected to pcb ?

    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 :-(

    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

    (ctrl+z)

    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 part

    (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?

    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: :realmad: :realmad: :realmad:
