I got a new DVD burner a few weeks back. I thought it would enjoy life on my desk, but apparently not: it lies to me.
If I tell iTunes to burn an album to CD, the burner goes through the motion: LED flashing, motor whirring, etc.. And it finishes without reporting any errors. And then iTunes shows the contents of the newly-burned CD. And if I use Windows Explorer to look at the disc, I can see the songs files. It looks like the process worked.
But if I then eject the disc and look at it, I don't see that telltale slightly-lighter band where the songs should be. It looks ... blank. And if I put the disc back in the burner, the burner grinds and coughs as if I inserted a blank disc. And if I then look at the disc with Explorer, Windows tells me the disc is blank and asks me what I want to do with it. This is the same disc that Windows just said was full of music.
And yes, the disc is actually blank: I can burn it again. And sometimes the contents will actually be written.
This is baffling.
