"disc burner in use by another program"

Well, I spoke too soon. It burned one CD, then no more. Back to square one I guess....

What message do you get when itunes no longer burns discs? My theory is that there shouldn't be any _eject icon_ in the _Finder side bar_ for itunes to burn properly!

I am able to burn a disk from iTunes provided that I click Burn Disc before I insert a CD into the MacBook (the iTunes help file says to insert a CD first, and then click Burn.) When I do this iTunes tells me to insert a disk and all proceeds well - except on one occasion I wasn't able to eject the CD from iTunes after burning it and had to use the disk utility instead. I did not have to eject my WD Combo external hard drive for this to work.

Yup. That works.

I had these issues as well - popped up out of nowhere. followed these instructions, as I have a shared WD 2TB external HD, worked for me:

The common problem with this error recently is the new Western Digital MyBook drives. If you've added one then go to HD/Library/LaunchDaemons/ and delete the com.WD...Plist file that's there

Reboot machine, problem solved.

Woo hoo, that worked! Thanks! BUt I still don't know what the deal is with that bogus message...my burner was not in use... oh well.

yes, this situation where one has to be CUED to insert the disc in order to burn seems to exist on my system only since I installed Leopard. it's also been the case in other disc-burning programs, such as iDVD....(actually, Leopard made my disc-burning capacity in iDVD 5 obsolete and I got stuck buying the whole new iLife series in order to meet a deadline...only to run across the problem described in this thread with iTunes, all over again). annoying and counter-intuitive but at least my CD is burned.

I've got the MyBook Pro II 1TB connected to my eMac running 10.3.9.

Same error. The directory string for me was:

HD/Library/StartupItems/WDDriveService/StartupParameters.plist

Removing the "StartupParameters.plist" file seems to have solved the problem.

That'll stop WDDrvSrc from running at login. WDDrvSrc is (I think) the daemon that updates that neat little capacity light on the front of the drives.

If you don't want to do this, opening Activity Monitor and force quitting WDDrvSrc will also work. It did for me, at least.

That does work. Confirm.

It looks like that, unless cued by iTunes before insert, another program is set up to deal with inserted blank media and it does not step aside when iTunes (or other iLife programs) seeks to use it.

My CD preferences are set to open iTunes when blank CD is inserted but the problem still occurs.
