OH!! MY!! (The Cables were reversed) ** Controller now talking to DRIVE ***
Classic problem when dealing with these drives - the cables are never keyed. So you have to check them both ends, from diagrams, to make sure.
As for links, I reckon if you check over the boot floppy downloads I recommended (just download, put on floppy, examine floppy contents) should give you a working boot floppy.
The BIOS on these controllers is very, very limited. Typically they do require CONFIG.SYS to have an entry that points at a driver file. They are extremely small, but required. That's booting on a PC.
Reading the BB manual and setup guides is vital to going through Amiga to get at the data. Especially the bit about how JH0, main PC boot disk, is implemented - as PC hard disk partition, as Amiga partition, or as Amiga hard file (not true partition, but encoded). I think those are main 3 choices, this is further on in BB manual.
Yes, the old noises are very encouraging. I think you are nearly there now, in terms of stages. But it's understanding how the different systems need to be setup to access the drive that you are missing.
This last stage will probably take quite a lot of reading and experiment, but the actual steps needed are not that big. It is just getting them right that matters.
Drive sounds healthy, like I said, the magnetic domains are BIG on small capacity drives, so they tend to remember things very well in storage.
