For those using text browsers, the error message reads:
Unable to burn [disc]. The device failed to calibrate the laser power level for this media.
In all seriousness though, in all my years of burning optical media I've never come across this problem before. I'm crossing my fingers it's because the disc is dodgy and not a sign the laser mechanism is on its way out.
For those interested, I was burning a copy of FreeBSD to a DVD-R disc. Usually I use DVD+R media but this particular coaster was destined for an older machine.
