Be very carefull when heating those aluminum caps with hot air, they can explode easily.

Here we are

There appears to be a single oscillator on the PCB which clocks all the chips. Also, the two SATA-IDE bridges appear to share the same supplies, so this would rule out these two possibilities.

Is it possible to connect a drive to the data port of SATA 0 and then power it directly from your PSU, without going through the PC3000-UDMA card's current monitor circuitry? If this works, then try the same for SATA 1. This will tell you if there is any weirdness in the power section.

Sir im not sure what you are asking me... i can connect the sata directly to the motherboard but pc-3000 wont see it as sata 1 right? it will be seen as external drive therefore wont access to the HDD utility right??

i dont know why but with the multimeter the sata 1 controller IC gives wrong values.. "even if i swap and solder sata 0 controller IC over sata 1 location!
is it possible to bridge the sata filters from sata 0 to sata 1 IC controller?

Use the external sata power, connect sata data as normal. You will need to power up the channel to activate it in pc3K but it shouldn't matter where the power from the drive comes from - obviously you wont have control over the power from pc3K but that shouldn't matter for test purposes.

thank you for the explanation Sir i will do it

Sir i did what you said
"connect the HDD power DIRECTLY to the motherboard and sata cable to pc-3000"
but as i tought the PC-3000 shows the same status port 0 is ok but power 1 same status!

I think that your tests prove that the Spartan IC is faulty.

aaaaaaaaaaw you mean the main chip Sir??? thats a disaster! i guess is not easy to find on sale...right?

is it safe to reball or reflow? what temperature will you suggest??

As I see it, you have eliminated everything except the main chip. What else could it be?? As for reballing, I have no idea. You would need to consult the datasheet.

i guess maximum 260C for reflow

may i ask Sir? whats the voltage suppose to be on those pinout in the photo??
is it ok if i bridge with a wires from sata 0 controller IC to sata 1?

Yes, something is wrong there, but I don't understand what it is. Clearly the DC bias level of the Tx/Rx pairs differs between the two channels. There is a 1% 6.04K precision resistor (REXT) that sets the bias current (ISET) at pin #26. I would compare the voltages at these resistors.

See REXT/IEXT in this circuit diagram:

https://www.hddoracle.com/download/file.php?id=10650&mode=view

The REXT resistors are those two resistors in your most recent photo.

The only other thing I can suggest is to compare the voltages on each pin of the two bridge chips.

BTW, I notice that pin #29 of the bridge ICs in the circuit diagram is connected to a 3.3V supply, whereas on your PCB this pin appears to be grounded. :-?

Frank ,
Another Very Common problem is power section of this board

@Amarbir, the OP still has the same problem after bypassing the power section of the PCB by connecting the drive directly to the PSU.

Hello again Sir
unfortunatelly the pins are not numbered..

can you tell me with a photo which are pin 26 and pin 29?
i dont have the chematic of pc-3000 udma

pin1 is marked with a dot on both the pcb and the chip. count it.

Sir iv notived a difference of voltage in pin 28 & 27 ! on sata 0 is about 8V but on sata 1 is only 3V.
i made a bridge with a thin wires but now both SATA 0 and SATA 1 is not recognized on pc-3000

any advice Sir?
