You always put the faster device ahead of the slower one.

What you need is a cradle for the HD and you will then be able to put it 
with the DVD. The last time I ever put an HD in the narrower slots was 
way back sometime in the very early '90s. With a cradle you can also 
remove the HD for security reasons (when I go away all the HDs get 
removed and safely stored).

The other alternative is to have one on channel #1 and the other on 
channel #2 (which I think you already had them this way).

SATA and PATA use the same control channels and instruction set - only 
difference is the actual connector meaning that you can buy a converter 
(SATA>PATA or PATA>SATA). And you can have both SATA and PATA/IDE 
devises in the same computer if this is what is worrying you about what 
you now have.
