Would having both on the same ide channel slow down the dvd copying? its taking me 90 to 120 minutes to copy a 5 gig file at the minute,other times it does it in 10 with the same settings,cant seem to find the link.

Is one set as Master and the other as Slave?

Yep DVD/RW is Master CD/RW slave.

Doesn't appear to be any obvious reason as to why you should have problems unless there's a loose/damaged cable or lead.

Unless you were copying from the CDRW to the DVD writer I can't see why there would be any speed difference whatsoever, odd I must admit. Are you by any chance burning to different makes of blank DVDs because this can make a huge difference to burn speed. I've got 2 makes of DVDs both rated at 16x but one burns at 16x and the other only burns at 8x. I presume either the DVD writer or the software doesn't like one of the brands for some reason.

ensure when you copying on the dvd-r drive that there is no cd inserted on the cd-rw (slave) drive, i have noticed copying slowup if i have a cd in my slave drive as the drive is periodically accessed if i have a disc in, even though i'm copying on dvd-r (master) drive...

I have tried 2 different kinds of dvd one 4 speed 1 8 speed and it takes the same time to copy to both types,i dont copy from the cd to dvd i copy from files on my pc that burn straight to dvd.I dont have a cd in the drive,its odd i cant work it out either,i have a pioneer dvr 107d dvd/rw and an aopen cd/rw.

I looked around the options and my cd/rw drive was set to pio mode because of errors,cant think what errors it means it been behaving as far as i can tell,anyway i took out the cd/rw and left the dvd/rw on its own,have yet to try a copy.

You'll find the explanation here - if you can reconfigure the drives back to DMA mode it will definitely improve matters:

That a good page,im not sure i will put the cd/rw back in this pc may try it in another and see how it gets on.What i dont understand is if the cd/rw drive was in pio mode why that would slow the dvd/rw down,that was still set at ultra dma mode.

Tried another medium a JVC dvd 8x speed and it stated off at 500 minutes! lol then settled at 90 and i cant understand the times they seem to alter when the feel like it.I have checked the cables and they seem to be fine,im pretty sure it should'nt take 90 minutes at 8x speed.
