Ok . try to install the latest aspi layer ( system aspi ) from adaptec and reboot .
Check with nero infotool system aspi after that . If it is ok , try to burn .

You can try to set your CD/RW drive as master alone ( without the cd-rom drive ) then to set it as slave ( and the cd-rom drive as master ) .
Sometimes there is some weird issues .
You can try to uninstall your cd/rw drive in peripherals list ( at reboot it ll be redetected , i use this trick for some DMA issues under windows XP ).
if you have installed a virtual cd-rom/dvd-rom drive device uninstall it .
If it doesn't work may be you should go to your retailer to obtain a new drive or send a report/mail to MSI because in this case i think the drive can have some materials defects .
To your retailer say that nor nero nor cdrwin are able to use the drive on your computer and that it must have some defect .
Anyone has other ideas ?
if you want another reply from me or another people you should better to post your system config .
