Master or Slave?

How does one decide which to make master/slave?

I've got 2 DVDs and 2 HDDs... I'd assume I make the master the "primary" or faster drive and slave the other to it?

Also... On the jumper selector for the DVD drives... When would I use the "cable select" jumper?

Click to expand...

The master should contain your main partition or faster drive.

Cable select chooses master or slave depending on which connector the drive is connected to on the cable; the terminating connector is for master, the middle connector is for slave.
 
put a dvd drive and an hdd on single cable that way u get better performance than putting both hdds on the same cable.
It makes no difference in performance which one is slave or master. Master and slave will only effect automatic drive letter assignment.
 
IDE 1 = Main HD - Master / 2nd optical drive - Slave
IDE 2 = Main optical drive - Master / 2nd HD - Slave
 
IDE 1 makes sense... Why do you switch the IDE 2 order? What's this do for you? I'd assume you'd want the HDD as primary on IDE 2 also, like IDE 1
 
Okay - found this from another site...says that we don't want to put a HDD and an optical drive on the same channel - agree?

Hard Disk and ATAPI Device Channel Sharing: There are several reasons why optical drives (or other ATAPI devices) should not be shared on the same channel as a fast hard disk. ATAPI allows the use of the same physical channels as IDE/ATA, but it is not the same protocol; ATAPI uses a much more complicated command structure. Opticals are also generally much slower devices than hard disks, so they can slow a hard disk down when sharing a channel. Finally, some ATAPI devices cannot deal with DMA bus mastering drivers, and will cause a problem if you try to enable bus mastering for a hard disk on a channel they are using.
 
Ok... you got me... but... see my previous question in the post above about IDE2... What's the rationale for making the HDD slave?
 
I assume these are IDE drives and not SATA. SATA requires no jumpers. Otherwise, I would make it IDE1 master, IDE2 slave and then do the same with your Optical drives.
