A firmware update was available, but installing it didn't help. It would burn brand new DVDs perfect every time, but wouldn't burn ANY CDs properly.

Just that I had several of them die this way, but not all of them suffered this fate.
Not all Verbatim discs are using original Mitsubishi AZO dye. Many are from OEMs like Prodisc, Daxon, CMC Magnetics, etc. Its easy recognize AZO discs as the dye color is blue, rather than greenish silver. Referring to the attachments, out of those 3 models of the same brand, only two are using original Mitsubishi AZO dye which are Blue Platinum Super AZO HG and Crystal Black Sonic AZO. The first one is ordinary run-of-the-mill CDR whose OEM was Daxon, which is much cheaper as well.

Could be a problematic or defective drive. In other words, the CD burning side is malfunctioning...

Yes these failed Verbatim discs were deeply blue dyed. Will try to get a photo if I still have any. I threw most of the bad ones out. I do recall in the header it saying "Mitsubishi Chemical" on these discs.

The light green newer Verbatim stuff hasn't failed me yet but they're a LOT newer... I think the newer stuff had ATIP data that was pointing to some Indian company or something rather.

Mitsubishi Chemical is just a brand name, and is the same company as Verbatim. Besides, Prodisc is the only other OEM that has used AZO dye (for CDRs). Another blue color dye is cyanine, which can degrade easily. Some early CDRs uses cyanine (includes those from Verbatim, Taiyo Yuden, Sony, etc). The AZO dye based discs that failed me were those Metal AZO ones. These Metal AZO were deep blue in color. However those Super AZO HG and Sonic AZO discs which were lighter blue in color has been solid, retaining data over the years with hardly any degradation at all. Anyway, I don't buy Verbatim as its too generic (like Sony, TDK, etc), and usually prefer to stick to original Mitsubishi brand and model instead (that way I know which were the ones using original Mitsubishi dye)...

That sounds like Moser Baer...
