For a long time, I have had problems before boot: My primary master disk is sometimes not detected, and thus, the machine doesn't boot.

If these actions have an effect, I really do not know, and sometimes, like this morning, a lot more fiddling was required...


i'd replace the ide cables ... with new 80 conductor cable


What I see is that if the primary master disk isn't detected, the primary slave isn't either.


that'd depend on:
	- the jumper settings on your disk
	- the manufacturer of the disk
	- the disk controller

- it is normally, supposed to find the slave disk, even if the master
  is dead or non-existent


However, if I pull the IDE cable from the primary master, the primary slave is detected.


that probably means your jumpers on the disk is not right
	- set the jumpers on the disk to be both cable select
	or explicity set master on the disk at the end of the cable
	and explicity set slave ont he disk int he middle of the cable

	using master on the middle of the cable can create whackyness


Alvin,

But with 2 disks + CDR-W drive and no special IDE controller card the cable for ide1 to the second drive does not reach the CD in the middle position and the drive at the end. So it has to be done with the CD plugged to slave and plugged at the end of the cable.
