I bought a new 500 gig hard drive today. It came with an IDE cable with
a blue tip and the fine, tiny wires flat ribbon cable. Well it didn't
work with that cable. I have another cable like that that came with
another harddrive a few years ago. It don't work either. Only the old
fashioned IDE ribbon cables with the fat wires work. I thought the
wiring was the same; straight through; on both. So, what is it that I
don't know?

The newer style cable has 80 wires - 40 extra grounded wires to reduce
cross-talk between adjacent signal wires. Another difference: on the
old style, wire number 28 was cut between the two drive sockets. This
was support for cable select (CS) mode operation of two drive on one
IDE channel: the master drive was connected to the middle connector and the
slave to the end connector. For the newer 80-wire cable used with CS,
the master drive is connected to the end connector, slave in the middle
and blue connector goes to m/b.

So I take it if you have the 80 wire cable and do not have harddrives jumpered for cable select you get a defective condition?
