Bought a new Western Digital or IBM drive? Read this!

WD and IBM/Hitachi drives have specific jumpering for installations with and without slave drives.

IBM/Hitachi

Best practice these days is to just use Cable Select on all drives.

For a good explanation of cable select see

"Best practice these days is to just use Cable Select on all drives."

A rule I live and istall IDE devices by!

Seriously its litterally PnP for IDE. And any newer mobo of the past, what- 4 years. Supports CS. So why not use it?

If you happen to be using an older 40-conductor IDE/ATA cables , then you can not use cable select. If you do it will set both IDE devices to master and cause a conflict.

There are 40-conductor IDE/ATA cables available and if you use the link Clive Burns posted you will find out how to identify them.

Only one more thing, the Master/slave plug locations are reversed from 80-conductor cables. Master will be the middle plug and slave will be on the end.

Huh? Who told you that?

I know because I had one.

Went and found this to back up what I said....

Amazing - you learn something new every day!

Bill, there's another 40 conductor cable select enabled cable that has the master plug at one end and the Slave at the other.

The controller plug was in the middle.

I've never seen one, just read about them.

Cable Select is not something the mainboard needs to support. It's entirely between the cable and the drive. So what you actually need for CS is a CS-enabled IDE cable. Current 80-wire cables practically have to be; while with the older 40-wire flavor this feature is rarely seen outside major brand boxes.

Added a second WD HD on a 40 pin cable. Had to jumper the new drive as slave instead of CS because it did cause a conflict with the old one. Received an error message upon boot up saying that I had no HDs installed at all.

Left old WD drive jumpered as CS, new one as Slave and then booted up w/o any problems. Might also have happened as this is a Compaq with a Bios dating from 9/1999

Diana01,
Most 40 conductor cables are not cable select enabled. When you set the drive to CS then the cable will set the drive as master.

If you set both drives to CS then you've really set them both to master.

Good observation there, Bill. Maybe make this thread a sticky.

Hmmm - I thought it was already.

Using Cable Select with the standard 40-pin ATA ribbon cable configures the drive connected to the middle connector as the Master drive and the end connector as the Slave.

Using Cable Select with the 40-pin/80-conductor cable configures the drive connected to the end connector as the Master and the middle connector as Slave.

40-pin ATA ribbon cable and 40-pin/80-conductor cable???

is ATA ribbon cable the thick wired cable and the 80 conductor cable is thin wired and has more wires than ATA ribbon cable?

And what do cd roms use? like dvd rom and cd rw
Because my cdrom and cdrw are connected by think wired cables which i think is 80 conductor cable... Did i do anything wrong?

The thicker cable with fewer wires is the older 40-wire cable. It won't hold position when you bend it. The thinner cable that holds where you bend it is 80-pin. They are both ATA.

You can use whatever you like on CD drives.
