Strange things with my hard drive

This is not a good idea unless ide channels are limited.
The reason for this is that once one device is accessing the ide bus the other
device doesn't get a look in until the first device has finished.
The practical upshot of this is that installs from cdromt o hard disk go really slowly because
both devices want contention on the ide bus.
With the multitude of IDE devices these days it can be difficult to get the combinations right.
Slaving a cdrom to a burner is ok provided you don't want to do on-the-fly
copying with your cdrom to burner.
Slaving a burner to a hard drive can also cause problems if your i/o subsystem is not up to 
keeping both devices busy.
If you have a cdrom only put it master on the secondary controller if you don't have 2 hard drives or put it as
slave on the secondary if you have a hard drive on both controllers.
If you have a cdorm and a burner I cable like this:
primary master, hard drive.
Primary slave, empty
Secondary master, cd burner, secondary slave, cdrom.
I don't on-the-fly copy from cd to burner, I let the computer
put it on the hard drive as an intermediate step.

Regards, Kerry.
