The first one sounds like an ok ready-up, if the cable is bad, then the second one could be scrambled signalling

The cabling is done as 2 pairs. One long, one short, for each pair. I have labelled these with [1] and [2] respectively. The leftmost of each type is for HDD1, and the rightmost of each type is for HDD2.

Wrong!

Data cable connectors are separate for each of the drives.
Control cable connector is only one - in this case, there can be two HDDs on one control cable.
Some controllers even allow for four HDDs, all on one control cable.

The other 34-pin connector is for FDDs.

Exactly this. The 34-pin connector on the far right was indeed connected to a 3,5" floppy disk drive.

I'll try to fix the cable this weekend and test the hard drive on Monday.
