Hi all, I’ve been reading through this board for the last hour and a half and if anyone can help me out, I know its gonna be you.
I’ve had the 40125S for a few months now. It’s been burning fine, but never reallly got up to the full speed capacity of the drive. I’ve tried several different types of media. On all of them, when copying from disc to disc for instance, it takes almost 8 minutes. Finally I got fed up with it and tried to change a few things:
(for everything below, I’ve been using TDK 32x media)
First I switch the master and slave set up of my drives. I used to have the cd-rw as the slave, now its the master. No change. Actually, after this, Nero wouldn’t even give me the option of burning at more than 24x.
Next I upgraded the firmware. No change.
Checked DMA enabled - yes, no change. (it actually says it’s using UDMA)
I searched this forum for an hour and read the posts, about putting in the media first, then starting Nero. Uninstalling Nero, and trying again, etc. Nothing seemed to make a differnce.
Finally I was able to get Nero to allow me to burn at 32x, but only by disabling Smart-Burn which I read you’re not suppoed to do.
What else can I try? With Smart-Burn disabled, burning a full CD of mp3s took 3:30. Is this normal? How much extra time should be added for the decoding of the mp3s? Also, am I always going to have problems going from CD to CD since they’re on the same IDE cable?
Sorry for bombarding with questions. I’ll take any and all answers. 
Here’s the rest of my info:
Win 2K Advanced Server (SP3)
LTR-40125S
TDK 32x Media
Nero 5 (came with burner)

I just ran the speed test - the results are positive I think:
