Pri Slave Drive ATAPI Incompatible
Matots Apr-29-02 07:25 AM
Help! My CD drive is not working anymore. Along with the above message, I am having to press F1 in order to completely start up the computer. I have checked the cables and they seem to be working fine. The CD drive was not found in my device manager and I tried to Add Hardware and it was not recognized, then I manually selected the CD Drive and it came back with a message about internal conflicts. Why would that happen when it had been working before? Is it that my CD drive is not working or just setup incorrectly?

Try this:

Restart in Safe Mode.
Goto your Device manager.
Delete ALL cd-rom drives that are present.
shut down the system, Unplug it from power and open the case.
First, check the jumpers carefully:
Hard drive should be set to Master.
CD-Rom drive should be set to Slave.
There are only a few (Server) boards that use CableSelect.
There are also special cables needed for this.
Restart and check if it will be there again.

If not, Shut down again and unplug it from power.
Take the IDE cable from the CD-Rom drive.
If an extra IDE cable present, connect it to the Secondairy IDE on your Mainboard, Jumper your CD-Rom drive as Master (If that position is free afcourse!) and conect it to the second IDE cable.
Restart your system and see if it will do the trick.

If all of this does not work, Your CD-Rom drive has failed.

I have seen major brand desktops that use cable select and I do not believe they used a special cable. Believe ATA/66/100/133 drives will usually work with cable select, but I do not set them that way and have not experimented with cable select much. Larry

I had an course in Windows NT 4.0 Server and Workstation.
One of the things in it was that the student must build a Server himself with given computer parts.
I noticed that from one IDE cable with three connectors (2 for the devices and one for the mainboard) there are leads with has deliberately "broken" (Really, a gap from half a centimeter in the lead)
Each connector had a different "Broken" lead to it.

The master told me that was an Cable Select cable.

So i did come to that conclusion that way.

After poking around the Internet a little... You are probably correct for older 40-wire cables: they have to be modified; I just never noticed it. 80-wire (40-pin) ATA/66/100/133) are apparently wired differently and accommodate C/S without modification. I have not studied this in detail yet. All of the computers I have built use Master/Slave. Larry

So did I Larry.

The Cable Select cable was indeed an 40 Conductor cable.
I lay it aside and choose the standard Master/Slave configuration with the extra delivered IDE cable.
The Server worked well at once.
