ide order for hard drives and cdrom drives

[Raul A. Gallegos]

Hi.  I looked in the archives here and could not find anybody's opinions 
on how I should go about doing this.

My current setup is hda=40gb, hdc=40x-cdrw, hdd=16x-dvdrom.  I just 
purchased a 120gb hard drive.

What my question relates to is should I add the 120gb hdd on hdb or 
should I put it on hdc and have one of the cdrom drives on hdb instead?

Thanks.
