Which is master and which is slave?

HHD or CDROM? I always forget this🙂 Is it motherboard (blue) to CDROM (middle) to HHD (end) or motherboard (blue) to HHD (middle) to CDROM (end)?
 
Doesn't matter. What matters are the jumpers on the back of HD and CD-ROM that make them master or slave.
 
Option 1 is correct. The motherboard blue to CDROM middle to HDD end.

But CDROMs usually use regular 40-pin cables, and ATA66 and up HDD use 80-pin cables (with the blue connector on the motherboard end). Also, it is usually recommended that you keep your HDDs on a separate IDE channel from CDROMs.
 
All IDE cables have 40 pins, the difference is the number of wires. The ATA66/100 cables have 80 wires to reduce interference. They are backward compatible with ATA33 and earlier interfaces.

The position (Middle/End) doesn't make a difference for Master/Slave. It is the jumpers as someone else pointed out.


Having the CDROM & HDD on the same channel will hurt performance if you are ripping one to the other. It would be better (though not essential) to keep them on separate channels. I have my HDD & DVDROM on one channel and my CDRW on the secondary. My (perhaps misguided) theory is that I can copy better from either the HDD or DVD to the burner on separate channels.
