still not as clear as i was hoping for , first of ide cable & floppy drive cable are two diffrent types of cables and a floppy cable cant possibly connect/work with a hard drive or optical drive , now for the basics , every ide drive have a jumper settings in the back of it that determines if the drive will be a master or slave (this doesnt affect its performance it just determines which drive will be identified first,or will get a drive letter first) , when connecting 2 devices on the same ide cable its important to have em jumpered properly,its also a good practice not to connect an optical drive along with a hard drive on same ide cable , example of how to properly connect an ide cable:imagine this is an ide cable
connector 1 (blue) - goes to the motherboard ide socket
connector 2 (grey) - goes to the slave drive
connector 3 (black) - goes to the master drive
thats the standard color coding of 80 wires ide cables,in 40 wires ide cables all of the connectors are black but the principle remains same (middle connector to slave drive and the connector after that to the master drive) , considering your pioneer drive is udma4/ata66 you must use an 80 wires ide cable for it to work properly.
assuming its all jumpered/connected properly and with an 80 wires ide cable , then check the DMA , have a look here http://club.cdfreaks.com/showthread.php?t=101616
