Hard disks and CDR's on same IDE channel.

[KimLeece]

I ran AIDA32 last night on my system and noticed that I have put a CDRW on the Primary controller with the system hard disk (master and slave). On the second controller I have a CDR. This was probably because at the time I thought that I would be able to copy CD,s faster that way. Now I realise that I might have slowed down the hard disk. My question is this:- If I have an ATA100 hard disk as a master on the same channel as the CDRW (as slave) does this always limit the hard drive to the ATA66 (or whatever the CDRW's rating is - I'm not completely sure) or will the speed drop to the lower one only while the CDRW is in use, i.e while the CDRW is not in use will the hard drive run at ATA100? As I hardly ever do copy CD's I am beginning to think that I would be better to change the configuration and put both CD devices on the Secondary controller. The motherboard is an Asus A7V333/Raid. I have a RAID array for DV editing.

They share the bandwith in the ide channel . So it reduces tansfer rate if both are used simultaniously .
E.g it's faster to burn files from HDD on ide0 to CDRW on ide1 .
