a lot of rubbish

Hi,

Hope somebody can help me with my problem. I can't get to HDD command line.

My setup - 500gb seagate brick. Nokia Ca-42 cable (powered by 5v from another (faulty) celluar cable), tx and rx lines - loopback test passed, gnd - from Nokia cable, software - Hyperterm. Whole thing seems to be working fine, loopback test passed many times but when I connect power to HDD, I get lines of "garbage", on a page 84 I read that most often it's caused by GND cable problems, did a tripple check and tightened GND but still don't see anything useful in a terminal. I have two sources of power for hdd - 220v to SATA (part of external hdd interface) and a SATA power cable via adapter from MOLEX IDE connector from desktop pc. When I change powersources it result in different amount of garbage in terminal. Maybe someone can have an idea what's wrong with my setup?

Grounding should mean that ANY device connected is grounded together.

I.e. ALL boards/devices/whatever should have the 0V (usually black) cables connected together.

Do check also speed/parity settings in hyperterminal.

Try getting the power for the CA-42 by the SAME 220V to SATA PSU.
