Well Im giving up for tonight.
flashed 47N9 to 47L9 (it warned about being an older version).
I assume I don't have to go back to an early version, and flash forward?
Next copy stopped at 99%.
I watched the dialog box, and at 99% it did a bit of a minute pause then the close "X" icon in the top right of the nero burn box became active.
Clicking on it, gets the message the program is not responding and the disk will not eject from the drive. I had to do a re-boot.
Maybe I need to update XP, with service pack 2. I stayed away from it because I heard there were initial problems with it, but I assume it is ok now.
Maybe I'll take it to another computer with USB2.
If it fails there, then it is the drive or media.
I updated Nero from 22.214.171.124 to 126.96.36.199a.
4 disks ok, 5'th one stopped at 99%.
This is about what I expected if it didn't work.
The disks Im using right now are Fuji - Taiwan ProdiscF01 . dvd-r
I can try some +r, or maxell, memeorx, benq, dynex, Riteck, Ridata, Fuji - Japan TYG02, but I don't drink enough coffee to justify that many coasters.
I've been burning these Fuji all at 4x since qscan reports them as unacceptable at 8x. The nero burn options go up to 12x burn speed with the ProdiscF01.
The transfer and all the other tests on the main screen worked ok, good results.
The media check took 4 tries, but I got a cd-speed media check done with a quick scan.
It is intermitent, and stops with the parameter error (052602) error randomly, that I reported in another message in these forums.
The PIE avg 2.30 max 7
The PIF avg 0.17 max 4
Jitter avg 6.32% 11.3% max
PO Failures 0
cd-speed media check will run always to completion with firmware 47N9, but doesn't report the PIF errors.
I'm wondering if these 2 problems are related and is it only my configuration that is having these problems.
I will plug into another USB on this computer if that will help, and unplug my usb printer, and firewire scanner.
Any suggestions would be appreciated.
I'm not much into hardware and tweaking, although I can wield a 5 pound sledge hammer if I have to.
