IDE slave/master configuration?

I have a very basic question:

I have two hard drives and an IDE CD-RW. I intend to use the second hard drive for video editing.

Which devices am I better off configuring to share an IDE bus? The two hard drives, the HDD with windows on it and the CD-RW, or the data hard drive and the CD-RW?


Thanks,
weshuang
 
I would have your boot drive as primary channel Master, your second hard drive as secondary channel Master, then put your CD-RW as Slave on the opposite channel from the HD from which it will most often be receiving data.
. Of course the best of all worlds would be to buy an add on ATA adapter card so each could have its own channel. Silicon Image based ATA cards are very cheap (~$20.) and flexible (RAID or normal w/ just about any mix of drives).
. Be sure all drives are set to run in ATA/UDMA mode. If your CD-RW can't do at least ATA/UDMA 33, either get a new one or move it to its own channel.

You just caused me to waste about a half hour researching what UDMA is... 😉

Actually, I am using a drive which has the Highpoint RAID chip, and, I believe, two extra IDE buses. My mobo is the Epox 8K3A+. Any idea whether I can use the third bus so that everything operates as a master?
 
Yes I do believe you can use the Highpoint to drive normal HDs. In your case, I would put your boot drive on the primary raid channel, your second hard drive on the secondary raid channel and your CDRW on the primary normal IDE channel.
. Disable the secondary normal IDE channel in your BIOS. That will free up IRQ-15 for other uses (perhaps the RAID channels will use it). Also set in your BIOS to boot from the RAID controller. DO NOT SET UP ANY RAID in the RAID section of your BIOS - that would damage your data.
