It seems to be a common(ish) problem, mine's doing the same thing but it's out of warranty. I can't even find a replacement drive online! 😱
My drive is a Matshita UJ-857D, what's yours?
Nermal -- Although my MacBook Pro is nearly brand new, it was built in late January and I bought it in late March, I have the same disk player/burner as yours, which is in an, apparently, older machine:
MATSHITA DVD-R UJ-85J:
Firmware Revision: FBZ8
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: Insert media and refresh to show available burn speeds
How does this drive differ from the one in the OPs laptop?
I did some disk burning years ago, when I first got my old PowerBook G4, but havent done any on my new MB Pro.
