Ripping speed (slow)

[fb03er]

Hello,
I have Reference dBpoweramp Release 12.4, and I have a problem now.
I was ripping with ~40x ripping speed, and was very satisfied with it.
But now, I'm getting, at most, ~10x ripping speed, I haven't change any configuration or settings, and my drive seems to be working.
What should be wrong?

My drive settings, if helps:

Ripping with drive 'E: [HL-DT-ST - DVD-ROM GDR8163B]', Drive offset: 102, Overread Lead-in/out: No
AccurateRip: Active, Using C2: Yes, Cache: None, FUA Cache Invalidate: Yes
Pass 1 Drive Speed: Max, Pass 2 Drive Speed: Max
Bad Sector Re-rip:: Drive Speed: Max, Maximum Re-reads: 34

Thanks in advance.

Hello,
I've checked, and what I've found:

Primary IDE channel
Dispositive 0, current transfer mode: ultra DMA, mode 2
Dispositive 1, current transfer mode: DMA if possible, but it's not activated

Secondary IDE channel
Dispositive 0, current transfer mode: ultra DMA, mode 2
Dispositive 1, current transfer mode: PIO mode (I can't change it)

Any ideas?
Thanks
