|For your jumper setting chart if it is not printed on the hard drive you just need to Google the model number of the drive with 'jumper settings' right after it (no quotes and not other words). Try each of the first 6 or so results. as an alternative you can go to the hard drive manufacturer's website and go to Support and search there for your manual/chart.|
I recommend the Master setting for the primary drive on the cable and slave for the other. Using the 'cable select' option available on later IDE drives with the later cables is mainly so the factory assemblers do not have to stop and consider the jumpers while assembling the machine, they just need to remember which connector goes to which drive (all are preset for them).
You have to be a little bit crazy to keep you from going insane.
