    Posted · Edited by mcsoba

    Hello i need information on MY HD 160GB seagate

    After the command F3 1> N1
    I withdraw the power and wait 20 seconds I re-plug the cable
    And I receive this strange message> InitiatedMarkPendingReallocateRequest for disc_lba

    This freezers the terminal, Where is wrong? 

    After this I enter with Crt command
    After this I enter with  command CRTL+Z And I finish the process..
    F3 T> I4,1,22
    F3 T> m0,2,2,,,,22

    I'm problem with HyperTerminal,, I have connected cable usb/serial + adapter serial/TTL max232 + 3.3v orange power supply and Black GND + TX and RX on HD
     
    when I enter the HyperTerminal CTRL+Z It appears only strange symbols,,, the characters in different keyboards,,,

    I understand that I have to combine this ...
    even missing another converter until the PC port ...
     
    I think myself could fabricate this cable using only one DB9 male to USB, changing the pinout ....
    but i discover now this cable must be a professional,,right?
     
    is not so very simple this cable have to buy same,, why has microchip involved for this conversion,,right? http://www.ftdichip
     
    I thought it was just changing the pin DB9 to USB,,,,D+/TX,,,,D-/RX,,,,GND/GND

     

    thank you ...

    the other side of the board,,but this a bit erased I can identify.....

    VCC = CTS

    DCD = Data Carrier Detect = GND

    DSR = Data Set Ready = RXD

    RI = Ring Indicator = DTR

    RTS = Request To Send = TXD

    From Adapter (TX) to >>> RX (on Seagate)

    From Adapter (RX) to >>> TX (on Seagate)
