I've been duking it out with my EZQuest Boa 12x10x32 lately. I've owned the burner for about three years, so I realize having to do minor voodoo to get it to work is normal and it doesn't phase me.
But in the last week, it has failed every time I've tried to burn a CD. It's a fairly small one that I was trying to burn; just under 200 MB. Sometimes it would fail at the start of the operation, sometimes in the middle, and sometimes in the end. Up until this experience, the only problems I've had involved having trouble getting discs to mount.
I decided to take the drive apart and see if anything was wrong (given my knowledge of electronics, it wouldn't have made any difference - I just took some Hubert Farnsworthian pleasure out of dissecting its brain). I found nothing out of the ordinary. So I was up much of the night digging through the MacNN forum archives and the Internet, tweaking what I was doing as needed... tried a new FireWire cable, tried a different brand media, tried logging in as root to do it in case permissions were flaky. Nothing solved the problem. I wondered if the data could be corrupt, so I tried burning different data. I tried burning a music CD in iTunes, but it also failed. One last try with the Finder, but no luck. At the end of all this, I went to bed at 5 AM.
I woke up this morning, powered up my machine and crossed my fingers one last time. I clicked "Burn Disc" in the Finder, as I had been doing all along, and it worked! I couldn't believe my eyes, so I put in another disc, and voíla! It worked again!
The only reasonable explanation I can think of is that overnight I sleep-walked to the nearest shaman...
