Question about Pioneer DVR-112D DVD RW Dual Layer Burner

2 Answers


Dear Gurus, I replaced my internal DVD burner that shipped my Apple G4 dual 1 gig (MacOS 10.4.11) with a PIONEER DVD-RW  DVR-112D and at first worked well burning CDs and DVDs and reading all the CDs and DVDs I owned. Now I am having trouble reading some DVDs and CDs.....the actual DVD with drivers that came with it can't be read now, although, sometimes it will mysterioulsy read it or if  I shutdown with that DVD still in drive and boot back up....will appear on my desktop.
I used patch burn but have not rest the cuda/pmu chip....

Do I need to update the firmware? The current Firmware revision is 1.09.
The newest  Ihave seen is like 1.21 or something....but I only see updates for PCs, with .exe files, not for Mac OS....

    Hello early1234 and all Gurus....

    Thanks for the reply. I tried to clean the lens with the Maxell Lens Cleaner CD-345 (Brush system, no liquids or wiping by hand). It did not work.

    I also can't burn 32x CD-Rs. The specs say I should be able to burn up to 40x CD-R. When I attempt to burn thru iTunes, I get the this message" The attempt to burn disc failed. The burn failed because of a medium write error."

    When I use the application Toast 8 to burn a CD I get this message:

    The drive reported an error:

    Sense Key = HARDWARE ERROR

    Sense Code = 0x44, 0xD9


    I have had this less than a year. Again I am trying to run this on an Apple Power Mac G4 (Quicksilver 2002) Mac OS 10.4.11

I've just come across this notice from Pioneer. Sounds like you might be having the problem that they are describing in the faulty drives.

Pioneer is aware of a potential issue with the above drives’ CD (not DVD) read/write capability.

Check with a NEW PC - DVD Cable, if it is NOT that.. then I am sorry, but I reckon it's gone faulty somehow? Especially if it causes the PC to not boot. This is a common occurrence, even for NEW units..
