CD-ROM Jumper settings

I have a computer that has a DVD 8x drive and a TDK 40x12x48x49 (write x rewrite x read x rip). Which one of the drives should be the master on the secondary IDE channel. In the instructions for both of the drives, it says that both of them can be master, but only one can. I do not want to put either of them on the primary IDE channel because that would slow down performance when writing/reading to/from cd to/from hard drive.

Put one (the reader only) on the primary ide as slave with your HD(master) and the writer on the secondary ide as master, this way when copying from cd->cd you will not suffer buffer underruns and from hd -> cd will lose no perfomance either ***************************************
Party on, dudes!

This question comes up at least once a week and we all get into the same debate about what is best because either way is a compromise.
Personally I would leave the hardrive on it's own and set the writer to secondary master, DVD to secondary slave.
Better still buy an PCI to IDE controller card which will give you two extra channels leaving all your devices as master on there own channel. Martin Just trying to help, sometimes falling short, I am only human after all.

Trouble with PCI ide caards is they use up valuable IRQ's and in most peeps machines these days there aren't enough to start with, with the way I suggest you only lose performance copying from the primary slave to the hard disk and thats no biggy if your writer is a40+ speed reader anyway.

The cost of a pci ide controller is somewhere near a 40gig hard disk, buy one of those instead and slap it on as seconday slave and its a win win situation ;-) ***************************************

I still disagree.
You will slow the hard drive down (presumably ATA 100) to the slowest device on the channel (the ATA33 DVD 8x)
The writer is burnproof so although putting it on the same channel with the DVD might slow it down a little the burnproof technology should ensure reliable writing.
But as I said both are a compromise and in real world use you may not even notice a performance hit either way.

It also depends upon the motherboard and interface. Some motherboards put only the Primary IDE interface on the PCI bus. The Secondary IDE interface channel is actually connected to the ISA bus interface, thereby suffering from a substantially slower theorectically throughput than the Primary.
