when i initially installed a cdwriter on this machine i could never
enable dma on that drive. the drive would dissappear from explorer,
would not be recognized by nero, etc. I used a dvdrom on secondary
slave. the dvdrom drive would work fine with dma enabled and finally i
gave up trying and used the cdwriter with PIO mode only. now that i
have upgraded my cdwriter to a dvdwriter i am faced with exactly the
same problem. i know i can increase my write speeds if i can get the
devices to allow dma, but how??
mboard-kd7 vanilla (no raid, no serial ata, etc)
running winxp sp1
primary master -80gb WD hdd
primary slave -20gb maxtor
sec. master -afreey 12x dvdrom drive
sec. slave -liteon ldw-451s 4x dvdwriter
PS- i tried switching the dvdrom and the dvdwriter with the result
that the writer would not accept dma mode in either master or slave
configuration. thanks!

This article may help explain why you're having the problem. Near the
bottom of the page, it shows you how to enable DMA (if XP will allow
it).
One other thought; you should be using a 80 conductor, 40 pin IDE cable.

ICee-
Thanks for the help. Somehow tho, I've been able to change both
optical drives from PIO mode by disabling UDMA access for the
secondary ide channel in the bios. now both drives are running in:
Multi-word DMA mode2 - whatever that is... hopefully since it has the
word DMA in it then it is at least a little faster than PIO mode...
PS- I am using a ata133-80conductor/40pin cable... forgot to mention
it. If someone out there still wants to help me get these drives
working in Ultra DMA mode- please! thanks everyone.

Well, you're up to 16.6 MB/s transfer speed with Multiword DMA Mode 2
(twice POI mode 4 speed). Have you tried the DVD-RW drive alone as
master on the cable; does UDMA work then? What is the maximum transfer
speed of the DVD-RW?

I would try another cable and install the DVD-RW drive as master and the
other as slave. Some CD-RW/DVD-RW drives must be set as master for them
to work correctly.

Icee-
I'm going to try to enable UDMA with only the dvd burner installed as
master on the 2ndary ide cable- if that works then the Afreey dvdrom
drive is the suspected culprit in the whole deal; ironically it has
had no trouble being set as UDMA !! :) It kindof figures. :)

Sounds like a plan. Yes, sometimes different drives don't like to play
well with others. :) Post back with the results and we'll go from
there.

Icee- I got my copy of Nero finally so was able to play with the
drives- and since I can do onthefly cd copies in about 6-7minutes and
dvd copies in about 10-11minutes (that doesn't include decoding
time-just burning time!) I am gonna leave everything like it is for a
while. at least I'm not running in PIO and I feel like the drive is
plenty fast as far as burn speed. especially for a 4x drive. Thanks
again for the help-

Sounds good. Thanks for the update, and you're welcome.
