First thing I need to know is the O/S
Typically when you add a device the system will recognize it and attempt to install the appropriate driver, you need to tell it to look at the CD I assume came with the device.
Once you have installed it look at the list of devices in DM and see that the correct model devices show up. Double click on the new device and look at properties, make sure it has the correct characteristics of the device there.
Going back to another post, I would ask did you replace a precious device (CD rom) The posters are correct, if the cable has the twist in the leads going to the second position then cable select or Auto will be best. If you had a previous device installed, you may need to remove it from the list in Device Manager to remove and confusion on the O/S part the features this device represents to it
Let me know if this helps
As mentioned in another post, control panel (XP) computer management, storage management will list all available devices. It will assign the next device number to this drive, you can change it there in the future should you need to.
OS is XP. Deleted both CD-ROMs from Device Manager and restarted. Put DVD in top drive (F?) and it recognizes it. Put DVD in bottom drive (G?) and it does not recognize it, although “G” shows up on the list of drives. It asks me to place a disk in drive “G”. So, I put it in the top drive (F?) and it recognized it. So, is the computer seeing the primary top RW drive as both “F” and “G”. Pulling hair out.
