So I recently came into possession of a new-looking DVR-112D PATA burner (not a single scratch on it, and almost not a speck of dust in the tray), which was clearly disclosed to me beforehand as having problems, but since the cost to me was essentially about $5.00 USD, I decided to acquire it out of curiosity and to test.
The drive came with stock 1.21 firmware and had a manufacture date of June 2007. Testing the drive out of the box, it burned and read DVDs just fine. Then I tried to burn a CD…
Not only could the drive not burn CDs, but it wouldn’t even load or recognize blank CD media, nor commercially pressed CDs.
I then flashed it to stock 1.24 firmware, using the official Pioneer flasher, and went through the tests again. Still handled DVDs fine, still no recognition of CDs. I concluded I had one of the classic Pioneer defective DVR-112Ds, which were not supposed to exist as late as June of 2007.
While the drive is out of warranty, past statements by Pioneer seemed to indicate that for drives that had this very specific problem, which amounted to a recall, they would repair or replace them, irrespective of warranty length. Of course, I doubt that is the case, since they are a corporation after all, but I may just harass them a little just to see what their tech support is like, before I have to use it for something important.
In any event, the original point I wanted to make is that Pioneer lied (big surprise…NOT!), and their entire production run of DVR-112Ds may have been defective.
That is all.
