Just a quick question, is the drive set to be secondary master? Also (and this may help) make sure that the driver for your IDE primary/secondary channel controller on the motherboard are set for the defaulth MS ones. You can do this by following the following steps:
Right click on my computer->Properties->
Hardware tab->Device manager (middle -right)
Expand IDE ATA/ATAPI controllers
Will have intel / Via / nvidia Ultra ATA storage controller (or similar)
Don’t do the primary or secondary channels. They are children of the main.
Right click on the Via /Intel / Nvidia Ultra ATA / IDE controlller and select “Update driver”.
Then select “install from a list or specific location”-> next
Select “Don’t search. i will choose the driver to install” -> next
Select “standard Dual Channel PCI IDE Controller (or similar)” -> next
Reboot machine to take effect.
Also, I think there are other posts regarding DVD drives being recognized as only CD-RW drives so try doing a search as well. Hope this fixes any problems
