Hi,
If it is the case, you may need to physically check the
connection of the CD-rom and CD/RW. Make sure the jumpers
have been set correctly. For example, CD-Rom - master and
CD/RW - slave. I think you are using a 40 Pin flat ribbon
cable. Ensure the far end connector is connected to the
CD-rom and the middle connector is connected to the CD/RW.
Then boot into BIOS and check the secondary IDE
connection. Your CD-rom should be in the secondary -
master and CD/RW in secondary - slave. Set the CD-rom to
enable DMA mode and the CD/RW to PIO mode then save and
exit. After windows startup, go to device manager and
click the IDE ATA/ATAPI controller, click the secondary
IDE channel and then click the advance tab, the device 0
should show the present transfer mode is Ultra DMA 3,4 or
5 and the device 1 show PIO mode.
Try copy disk to disk again. If the symptom persists, go
to device manager and remove the CD-rom and then reboot.
Let windows search and reload the drivers and then try
again.
BTW, what burning softwares you are using?
I use Clone CD, Nero 5.5 and XP burning features (Roxio)
in my XP Pro without any problems.
If it is still no avail, there may be a hardware problem
and you may consider for a new DVD rom.
Hope it helps.
