EIDE Cables

I understand the concept of Master, Slave and Cable Select
associated with the EIDE devices. But I have a problem
understanding the cable. If I have a cable with black,
blue, and gray connectors, do I use the Cable Select
jumper settings for the two drives? If I have only one
drive, I know I have to use the end connector, but do I
set the jumper to Master or Cable Select? Are there any
noticeable feature on the cable to suggest Master/Slave or
Cable Select, particularly the rounded cable?

Thanks!

Mostly it doesn't matter which you do.

Normally those colour coded cables are ready to use with cable select.
I think it's usually:
Blue - motherboard
Black - Master
White - Slave
So normally you can just leave both the drives as cable select.
Or you can set the jumpers to master and slave too if you wish.
Just occasionally you will find an old motherboard which will not let
you use cable select even with the colour coded cable in which case you
must set the jumpers on the drives correctly for master or slave.
 
Go to the web site of the drive manufacturer. They all have very good
instructions on how to manage their respective hard drives.

Thanks for your reply.

If I decide to use the Master and Slave jumpers for two
drives, do I then must conform with the cable connectors?
That is, do I connect the drive with the Master jumper
setting to the Black connector? And correspondingly,
connect the drive with the Slave jumper setting to the
White (Gray) connector?

Thanks again.
 
If the drives are jumpered master/slave then position on the
cable doesn't matter. If set to cable select then position
control the setting.

The colors are for convenience.

Hello
The difference between the cables with the blue end they are 80 wire 40 pin
IDE cables, blue end to the MB.
It is always better to set the jumpers to Master and slave, never hook a
single or master drive to the center of the IDE cable.

A standard 40-wire IDE cable WILL work with ATA-33, ATA-66, ATA-100 or
ATA-133 drives but it will only allow 33MB/s performance. However, it is
recommended that you use an Ultra ATA 80-wire/40-pin cable no matter what
your drive rating for several reasons:

1.. 80-wire/40-pin cables offer improved data reliability and signal
integrity by adding 40 more ground wires than standard 40-wire/40-pin IDE
cables. The extra 40 strands in an 80-wire cable act as insulators between
the 40 signaling strands to prevent and reduce crosstalk.
2.. Using an 80-wire cable allows for the use of ATA/66 and ATA/100 modes
with drives and systems that support these rates. If you have an ATA/100 or
ATA/66 drive without the 80-wire cable, the drive will only run at 33MB/sec.
3.. You can use an ATA/33 drive on the same cable as an ATA/100 drive, and
with a current controller that provides independent device timing, it will
not affect the operation of an ATA/66 or ATA/100 drive. This is not possible
with a standard 40-wire IDE cable.
