have had a 108 for about a week now and I cannot write at more than 2 X. I’ll put the details below, if anyone can see anything obvious I missed then let me know please ! Sorry if its a bit verbose but im hoping the details might ring a bell with someone. If not then I think I’ll be buying a new motherboard
1 GIG ram
80 GB seagate hard drive
Window XP home
GFX 5900 XT
250W power supply
Pioneer 108 if the master on the secondary channel
CDRW is its slave (though I have tried unplugging it)
Hardrive is Master on primary channel (jumper set to cable select)
Software : Latest versions of Alcohol / Nero / DVD Decrypter.
Media : Ritek printable G04 and Datawrite 8x Fuji03
What I have tried : -
Extensive testing of Ultra DMA. According to XP UDMA is active on the 108 (current protocol is Mode 4). I have tried deleting all IDE channels from device manager and let XP redetect… but no change.
There are NO settings for UDMA in my bios - its a ‘bios for dummies’ with very few options to change - no update available.
New IDE cables installed - no change
Changing IDE channel of the 108 - no change.
Complete factory restore of hard drive ! Yip, I was sure this would fix it… took ages ! But no change
Drive installed on mates PC - burns faster than 2 X
Updated drive with hacked firmware - still maximum burn speed is 2 X
What I have noticed
Alcohol and Nero both accept burn speed of 4X / 6X / 8X. They will both tell you the burn has been successful at this speed also. However, the burn always takes 30 minutes (2 speed).
DVD Decrypter - also accepts 4, 6 or 8 speed. BUT as DVD decrypter gives you a ‘current burn speed’ thorough out I can see that it creeps up to 2 X then stays there ! In fact, here is the log, as you can see, 4 speed chosen, Maximum write rate 2.0x : -

- If I actually CHOOSE to write at 2 speed then I get smooth burn with the DEVICE BUFFER staying steadily filled.
If I choose a faster speed, the device buffer if flying up and down throughout the burn (and it still burns at 2 x ).
My CPU usage is at 90 % + during a 2 speed burn.(this is after closing all unnecessary programs down in task manager)
As for reading DVD’s - speed gets up to about 10 X ! Takes about 6 minutes to make an image.
Could my 250 w power supply have anything to do with it ? (I have tried unplugging the graphics card / floopy and CD drive before booting to no avail)
Thats it guys, I’d appreciate any feedback.
