Pioneer A04 and UDMA mode 2

Hiya,

Before i lost a hd due to a trash! My Pioneer A04 was burning dvd's quite happily in UDMA Mode 2. After the re-install of WinXP, I can no longer use the dvd writer in this mode!

It writes the lead-in and then quits!

However, if I run the drive in PIO Mode 4, everything is fine!

I have updated to the latest ASPI drivers (4.711) and still the same! This is annoying the hell outta me as it used to run fine in UDMA mode!

Anyone else here have similar probs and got a fix?

T.I.A.

Update:

I was getting so pi**ed off that I asked my mate to try the same brand dvd's that I am having the problems with. His writer burned them no problem and his drive is running in Ultra UDMA mode and not PIO!

So this confuses me even more! Like I said above, I never had any issues before with UDMA and my A04, so why has it stopped burning dvd's unless I goto PIO mode?

Anyone? I am spending a small fortune on dvd-r's just to bin them 10 mins later :(

i dont know what the problem could be but i got a question "However, if I run the drive in PIO Mode 4, everything is fine!" if it runs in that mode fine why not just use it in that mode?

Ahhh...

Maybe I should have explained. PIO mode is rubbish! It hogs your whole system and slows everything down. In other words, you can't do much else apart from sit back and wait until the burn is completed.

There is also the chance of a bad write coz the buffer underun kicks in a lot in PIO mode, which is nice to check that buffer underun actually works, but I hate to think of it ever being required. Never had to reply on it before, and dont wanna start now!

Hope that clears that up?

PIO = Slow/Possible underuns
Ultra DMA = Fast/Safer

tried rebuilding the system? although its built properly originally, sometimes going back to basics helps.

This is a Fresh format and re-install of WindowsXP like I said in the original post.

Didnt have any problems before the "going back to base" though! Seems somthing is not quite right!

Oh well...
