Just a WAG but could it be a drive firmware problem?

I found this thread on rpc1.org


Some Pioneer drives are FLASH_able some are not depending on the OEM. There 
maybe other threads on the rpc.1 forums regarding the  DVR-127D. --glen

Have you tried this in safe mode? I actually don't know if burning will work or 
not, but it will limit the number of variables.

I've never seen this, but I've never done more than one or two disks at a time, 
and haven't run 10.4 in a long time. 

What happens if you do it the geeky way:




Maybe some bug in the GUI version...

hum.  Lemme see if I can dig up an old vers of Toast.


Do smaller files burn OK with the same set up ?


Same symptoms.


All cables and ports clean?


Yea.  Did a deep cleaning with a sukolux recently.  No behavior 
change before or after.

Yes.  No diff.


Other brand disks?


Yes.  TDK, Maxell, and Office Despot.  No diff.  Same results with 
+RW, +R, and -RW.


Is the optical lens clean and free of hairballs? I have had that 
problem with old drives.


Ran a cleaning disc thru several times.  No diff.


Have you tried a logging utility to get a better error record?


As I said in my OP, there's nothing being thrown into the logs other 
than the failure notice.  Is there some other tools that watches 
burners in some special way?

with old drives.

Also old dry grease on the gear track can gum the write process.

Have you tried a logging utility to get a better error record?
