  1. Claro que si, pregunta y te respondo, pero mejor hazlo a mi email: jose7007@hotmail.com, que aqui a veces me limitan los mensajes.



  2. I cannot access to the hard details with my PC too and it donot detect in my laptop bios but I think its motor work and I hear its voice good. because I saved my Maxtor hard drive (STM3500320AS) that donot detected in my pc before with this topic ways,I think maybe I could solve this hard problem too with this way. My laptop hard information: Model : WD3200BEVT S/N : WD - WXE508FH4819 Anybody had this problem before? Can you guide me? Best Regards, SHP Anybody donot know the answer? I think you have BSY problem. STM3500320AS of maxtor works as ST3500320AS of Seagate. You need "RS232 to TTL adapter" or "USB to TTL adapter" to repair it. To unmount the PCB you need torx 6 screwdriver.
  3. Sometime I have stopped it and no problem, two hours is too. But it is a risk.Have you BSY problem? Have you unmounted the electronic board? Did you do the required steps of power off and power on after each stage? Can you tell me your firmware version? SD15?
  4. Hello! I have the same problem. HD: Seagate 7200.11 500Gb Firm: SD81 RS232/TTL: Handmade (I made it with ST232 using the unlocking guide ST310014ACE by cyd0g. The capacitors are 10uF (original 0.1uF)) Loopback test: Works fine! I can't tried separated the motor contacts or PCB off the drive. Ideas, please?. Thanks a lot!. PD: I'm thinking purchase Generic CA-42 Nokia cable. It's a good idea?. Have you cross the RX an TX lines? RX Hdd <-- TX cable TX Hdd <-- RX cable GND <-- GND What power supply do you use for the adapter? +5V from floppydisk's connector?
  5. If you don't find the USB device, you can:1.- Test the pinouts of USB connector and mobile connector with a multimeter 2.- Try unmount the plastic case, if there is an electronic board with integrateds circuits the cable is good. If your cable is wrong I can send you the correct cable with all the connectors and cables mounteds.
  6. May be you have a false cable. You can probe it with a multimeter (between USB connector and mobile connector).
  7. Have you unmounted the electronic board?(Before of F3 2>Z)
  8. The TTL converter works, you need power it from 3V bateries or from +5V floppy connector.You never have to get out the PCB with power on. This is dangerous. You have to unmount the pcb, power it, do steps, put the pcb over hdd and spin up the motor.
  9. You don't use the card, it is better unmount the PCB completly.You must join the RXs with the TXs: RX hdd <-- TX Adapter TX hdd --> RX Adapter GND <--> GND If Ctrl+z no prompt then you have a bad connection or your USB drivers are wrong. Can you do a loopback test?
  10. Black arrow is the symbol of Ctrl+z.Your RX and TX wires are joined. You have to separate them.
  11. On HDD:pin 1 (RX hdd) <--- TX Adapter pin 2 (TX hdd) ---> RX Adapter pin 3 (GND hdd) <---> GND Adapter pin 4 (N.C. hdd)
