Got this IDE+Floppy card off ebay and it's dead. Carefully inspected the traces and came across this. Weird damage. Was this a botched repair you think?
This doesn't look like an attempted repair, but to scratching damage. I had something similar happen to my Adaptec 1542B, when I put it into the same antistatic bag as a more modern graphics card. I placed those cards solder-side to solder-side, which usually turns out well, but in this case, the screws used to mount the fan on the graphics card had sharp edges and scratched some PCB traces on the controller. The result looked very much like in your picture. The card has already been repaired.
It looks like you have just a single torn trace. Scratch the solder resist on both sides of the damage, solder strand of copper wire over the gap and isolate/fixate it, for example with nail polish. Also use it to isolate the two traces where the solder resist has been scratched, but the traces are still OK. If you can't do it yourself, find someone who can. It looks like damage that is easy to fix for a trained person.
I agree if all that's wrong is that one damaged trace then the card should be fixable.
Huh.
Believe it or not the traces check out good.
I buzzed them both out and triple checked I was on the right traces. Good continuity. Guess something else is wrong with this controller.
Can you post more pictures of the card? Also check all the chips just in case any of the legs are bent and touching.
It's a pretty basic card. Just IDE + Floppy.
I think the crystal might be dead that's why it's missing in this photo. I get 0Hz on my multimeter when I test it. Whereas I get a reading when I test the mobo oscillator. (Powered up of course)
I already tested all the resistors and D1.
That very well could be it. Can't hurt to replace the crystal and see what happens.
Crystal is missing, someone took it back then.

He said he removed it himself to test it.
Guess what. I'm dumb 🤣.
I was using an ATX->AT adapter and the board required -5 volts. It works now with a legit AT power supply.
Excellent news glad to hear you got it all sorted out
That says lot to make sure you have a power supply with -5V this usually will solve the mystery of not working stuff.
