[G4] What Have I Done To Deserve This

[gifutiger]

Greetings ( + )!( + )

I concede, if there isn't a Cable Select jumper on the drive then they  
should be jumped as Master/Slave. However with the cable that is  
provide with the G4 the Master drive will still be the one that is  
closest to the Disk Controller.

One last point that I would like to make is that the jumpers on all  
drives are not the same. Even if they are from the same manufacturer  
the jumpers may be different. So make sure that you read the  
documentation on the drive and set the jumpers accordingly.

Once upon a time I installed a drive and just copied the jumper from  
one drive to the other. That didn't work because of a number of  
things. One being that I missed a jumper that told the IDE electronics  
on the drive that the complete size of the drive should be made  
available to the controller.


Cheers
