It wouldn't cause any issues changing the drive. Were just talking  
about the cable. If you use an ATA33 drive on a 80 pin cable it works  
fine it just runs at ATA33 speed. My problem is I have an ATA100 drive  
and 80 pin cable but Linux thinks I have a 40 pin cable therefore it  
is only running at ATA33 speed.

Thanks - Joe
