I hope someone can help. Here is my system:
E6750, Abit IP35 Pro, 1 IDE Connection, 6 SATA, Crucial Ballistic 2048 MB, ATI Radion HD 2600 Pro,
HP DVD+-R/RW DL IDE, LiteOn DVD +-R/RW DL IDE, ViewSonic VA2226w, Windows XP Home SP3, all drivers current including BIOS

I have been very happy with my system EXEPT for the fact that I can only use 1 DVD at a time. (1 must remane unplugged) With both drives connected they will read, rip, but not burn. I have spent many an hour researching this problem, including removing Roxio and Nero, using an adapter to send one drive to SATA, checking cables, etc. Abit is no help- they offer basic troubleshooting help or risky RMA. I finally, out of frustration, took my case to Best Buy and let them try. They were also unsuccessful. I have come to the conclusion that it must be a IDE controller issue. Am I offbase? Anyone else experienced anything like this? Love to hear from you. Please let me know what additional info you need. Thanks in advance....

Looks like you don't have the IDE drives hooked up right. Put one drive as Master other as Slave. Or put it in cable select.

I had a similar issue with an older computer that used Plexor IDE drives. Hooking them up as master and slave didn't help in my case. It seemed to be a controller problem, as you have surmised. The only way I could run two drives was if one of them was a read only disk drive. I simply adjusted to the idea that only one drive could be a write/rewrite disk drive.

Thanks to both of you gentleman. Yes I know of the master/slave/cable direct configuration....
Sailer, how am I going to tell my system that one DVD drive is read only and have it recognize it that way?

In my case, I had to buy a drive that was read only. Once it installed, everything worked fine. I used the read/write drive I took out in a separate computer.
