Honestly, I don't know how to do ccd myself.  But ccd'ing two ide drives 
isn't going to get you any increase in bandwidth or transaction times.  
Why?  Cause ide is broken and won't allow concurrent operations over two 
drives on a chain.  Which, btw, really sucks, when a cdrom and a fast hd 
are on the same chain so when the cdrom is taking a long time completing 
an operation (especially evident when it has a read error), i/o to your 
hd is completely blocked.  Blech.

If you want to do ccd in any useful form, SCSI is the only way to go.
