This is a different problem from the usual Roxio repair. I have two dvd/cd read writers. Sony DRU 810A and DRU 840A. One is a master on a single eide ribbon. The other is a slave on a second eide ribbon. Let's call them D: and E:. If I go the properties of D: and click and apply ENABLE CD recording on this drive, when closed it works properly, but E: will GIVE me an ERROR message if either a blank cd is inserted or the drive is empty. I can do the same to E: and then D; will give me the error. If a blank disk is in the drive it will say X:\ is not accessible. Incorrect function. If nothing is in the drive it will say Please insert a disk into drive X: It is not possible to get them to live in write mode at the same time. Is this a normal function of Windows or something in my setup? Nero will burn a disk in either position when asked, but if I want to drag files to the cd window to burn them on the fly, I can do it with only one of the drives at a time.
The system is W XPs3, 1 gig of ram. p4 processor. Not sure when this started, but it bugs me.You should chose which drive.to do whatever you want............

[conflict of drives USED to perform funtions!]Have you tried to SET up the second drive on the same ribbon?The optical drives should be setup on IDE2 as master and slave on the same ribbon cable...
Replace the ribbon cable.

Any reason you have it setup this way ? ?
