I can't understand this. My cd/dvd drive on my macbook pro has recently not been mounting blank dvd's. This also occurs with dvd's that contain data. Yet, cd/rw's and regular cd's mount fine. anyone know a fix to this problem?

So this happens with all DVDs or just blanks and data discs? Put in a DVD that your drive doesn't like, then open up Terminal and type sudo dmesg | tail and post the output here.

Are you running a Parallels VM while this is happening? If so, make sure you've installed all the guest tools correctly.

Another possible reason the drive is not reading DVDs: Usually when the optical sensor light on the drive is failing, the first type of media it refuses to read are DVDs. Why? Because reading and writing to a DVD requires more power. So while CD type media can be written to and read, DVD media can not.

Try cleaning the drive with a cleaning kit and see if that helps any.

Regards.

chscag, this is exactly what's happening to me. I can read CDs, but not DVDs.

When you say that optical sensor light is failing, do you mean like dying for good or just sensor being dirty? :)

Will try cleaning anyway.
Thanks.

Oh yes, forgot to paste what I get when insert a DVD and run sudo dmesg | tail in Terminal. Thanks for that tip.
