If that doesn't work, unreadable may mean that Windows thinks it is broken. If you've only got a single drive on the cable, and it is set to slave, that may well be the problem - you can't have a slave without a master.
My suggestion is that you set any devices that you are going to connect via that cable to "CS" (cable select). Once you've set them in that mode you shouldn't have to worry about changing the jumpers ever again, the cable position will sort it out.
If you are going to connect 2 drives to the cable, it doesn't matter which is connected where, the one at the end of the cable will be the master, the one in the middle will be the slave.
However, if you are only going to connect a single drive then you MUST connect it to the end of the cable. That's because there must always be a master on the cable, and with CS that's the end position.
Once you've set the jumpers correctly, go into bios and select IDE auto-detect. Make sure the bios detects the drives properly. If it detects them but windows still doesn't like your drive then it is probably faulty.
