MacPro Optical Drive – Won’t read burnt DVD’s
My DVD drive does not seem to be working properly.
I’m running a MacPro from early ’05….the optical drive is a Pioneer DVR-111D.
I don’t think I’ve ever had this problem before, so no bad history to describe….
The drive will not read certain burnt data DVD’s. I was trying to download files from a client that they sent on a burnt DVD, and it won’t read it. After a minute it just ejects it. I tested an authored DVD (official DVD Video), it worked fine. I tested a purchased Adobe data DVD (official DVD-ROM), it worked fine.
It’s reading CD’s fine….burnt or replicates (purchased).
Just yesterday I was able to download data from burnt (purple-backed) DVD’s. But not today.
The only DVD-R’s that it will recognize are blank ones. It recognizes them Just like normal.
I restarted the computer, blew some compressed air into the drive slot, wiped down the discs….still nothing.
I also tried burning some data onto a DVD-R. At the end of the burning process, it gave me an error code, saying that the burnt disc will not be reliable. When I re-entered that disc, it registered as a blank disc.
Any thoughts? Much appreciated.
