Help needed with new 40125W - Please!


I just bought a new 40125w and i’m having real problems copying CDs. This is my first Cd writer, so I may be doing something wrong!

I have 2 x Hard drives on my primary controller and the burner and a DVD drive (aopen 1040) on the secondary one. I have tried the burner as master and slave and there is no difference.

When I try an on-the-fly copy of audio and data Cds I get a ‘Communication Error’ in Nero. The log file shows this :-

14:49:25 #33 SCSI -1024 File Cdrdrv.cpp, Line 1415

Communication failure

I have tried the same via cloneCd and I get a hardware error.

If I use clonecd to create and image then burn it (including simulated) it seems Ok - but only wrte at 18x on 32x media (Imation) and also on 24x Sony media.

Should I be able to connect the burner and DVD on the same cable, or should they both be slaves to the hard drives - but will that slow them down ?

Shouldn’t the speeds be faster anyway ?

I’m using Win2k sp2 and the latest Nero and S05 firmware inthe drive.

Help me please before I go insane…


This is how I would have made the setup.

Primary master: boot harddrive
Primary slave: DVD
Secondary master: Writer
Secondary slave: 2nd harddrive.

cabling may be a problem though…depends on how your case is…

DMA is enabled?
The media supports high enough speeds? (Sony supports 32X max).
The drive starts writing at 19X so the average speed will be lower than the selected writespeed.

btw, upgrade to nero if you’ve not already done so.

Thanks I’ll try swapping the drives around. Will making the writer the 2nd master affect the hard drive’s performance ?

DMA was enabled - at some point !

The Sony Cds say 24x and the Imation 32x



only a info for the cabling according to Speed and U-DMA Modes !

You should conect HDD to the First IDE-Port
an the CD/DVD-ROM/CD-RW to the Second IDE-Port.

New HDD have transfer modes like U-DMA 2/4/5 :

U-DMA 2 = 33 MB/s ( Most/All CD/DVD-ROM/CD-RW and older HDD use this Mode )

U-DMA 4 = 66 MB/s ( Many newer HDD use this Mode )

U-DMA 5 = 100 MB/s ( All new HDD use this Mode )

So if you use a HDD with the U-DMA 5 ( 100 MB/s ) Mode AND A
CD/DVD-ROM/CD-RW with the U-DMA 2 ( 33 MB/s ) Mode On the same IDE-Port.

The U-DMA 2 devices forces the faster devices ( HDD U-DMA 4/5 ) to the slower Mode 2.
The IDE-BUS can only be as fast as the slowest device !!!

It is like a chain :
A chain is only as strong as the weakest part of it !!!

Cabling 1 : Works but not so effectiv !

HDD U-DMA 5-----CD/DVD/CD-RW U-DMA 2------------U-DMA 2

Cabling 2 : Works better than Cabling 1 but is no the best !

HDD U-DMA 5-----CD/DVD/CD-RW U-DMA 4------------U-DMA 4

Cabling 3 : Same as Cabling 1

HDD U-DMA 5-----HDD U-DMA 2-----------------------U-DMA 2

Cabling 4 : Till now the best Max Speed 66 MB/s

HDD U-DMA 5-----HDD U-DMA 4-----------------------U-DMA 4

Cabling 5 : Best Option aviable Max Speed 100 MB/s

HDD U-DMA 5-----HDD U-DMA 5-----------------------U-DMA 5

The same rules are for the cabling of CD/DVD/CD-RW Devices.

So the best cabling for the Max Speed is

CD/DVD/CD-RW U-DMA2--------CD/DVD/CD-RW U-DMA 2-----------U-DMA 2

This is the best cabling for CD/DVD/CD-RW Devices because
the most CD/DVD/CD-RW are currently U-DMA 2 Devices
( only a very few one´s have U-DMA 4 - Acer product´s i think - )
so they do not slow the other devices down.

But this all will be history with the new S-ATA :slight_smile: can´t wait for it.

hope this helps a little bit :wink:


For On The Fly copy´s you should use the config form OC-Freak.
It gives the best performance for On the Fly becaus the two
devices DVD-Rom and CD-RW are not on the same IDE-Channel
and the data-volume should be better handled fom the

good luck

Thanks for the replies.

Fixed by flashing the MOBO BIOS !!!
