Grab a PeeCee IDE cable, stripe one of the 40 wires with a blade(but keep the insulation)Follow the broken trace to the nearest exposed point (amiga side), then solder a patch from the first available exposed part of the connector to where it should be reaching to.
Never mind the performance, It isn't the UDMA133 of the modern PC but one of the first IDE implementations to refer to the standard! thus, long clear wires are unlikely to do harm. Even if worried, remove 3 wires instead of one, use the center wire to carry data then ground the 2 external at both sides.
Have done this before- worked as a charm.
Ah, and use a desoldering pump to remove excessive solder next time!
