Hi

My machine is recognising commercial CDs and CD-Rs with data on, but not blank CDs. I can't hear the disk spinning and it doesn't mount. I've tried a couple of different brands. When I restart with a blank CD in, my machine tries to book from it and then, of course, tells me it can't find a bootable volume.

Any ideas as to what's going on?

Thanks
Ben

Disk utility tells me the discs are locked and not writable. Not sure how/why, etc.

Did this happen after you updated to 10.3.7? If so, repair permissions. It may not fix it, but it's cheap and easy to do.

Sometimes after an OS update, new files are left with incorrect permissions. If the required driver for burning blank media has the wrong permissions, OSX may be unable to load that driver. No driver, no blank-media functionality.

Is this an original Apple-shipped optical drive?

Thanks. Yes, it's the original drive. I've been reading lots of stuff about this on the web. It seems there are lots of others with similiar issues, having updated to 10.3.7

I've repaired permissions with no joy. There are one or two suggested fixes, one of which requires locating a file I don't actually have in my library.

There are various threads on the macosxhints forums. Do I just wait for some offical fix?

Waiting for some official fix would require that the software and hardware on your machine be perfect. Experience tells me this probably isn't the case. Just from straight up statistics from my time on the bench, this is probably your optical drive going out. There is the possibility that this is software related, though. If you have another install of OS X that you can boot from to diagnose, do that (like another hard drive or Mac in target disk mode).

Thanks folks.

I seem to have found a fix - simply choosing 'open finder' under the blank CD options in Preferences. This isnt actually launching a finder window, which suggests that my machine is still not fully recognising the media, but opening one manually shows the CD listed with my drives (which it didn't before since this update).
