My new NEC DVD-RW drive, ND-3550A, is extremely slow at ripping audio
from CDs. Maybe 5-6x at most. On the same computer, when booted into
Windows XP, the drive is lightning fast (20x or higher).

This is Suse Linux 10:

# uname -a
Linux myhost 2.6.13-15.12-smp #1 SMP Thu Aug 24 11:23:58 UTC 2006
i686 i686 i386 GNU/Linux

DMA is enabled:

# /sbin/hdparm /dev/hdb
/dev/hdb:
IO_support = 3 (32-bit w/sync)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
HDIO_GETGEO failed: Invalid argument

I am using grip 3.2.0 for ripping, which seemed plenty fast with the
previous drive I owned.

Any ideas what to try next?

I haven't a clue, but maybe the ripping software. I noticed that things
were very slow when I used a GUI ripper (I forget which one), but when
I shifted to a command line ripper, it zipped along.

riplock perhaps? I know it affects DVD ripping. NEC are very
flashable. I have the exact same model... I flashed mine to remove
riplock. Google for more info on how to do this. Flash
utility runs on Linux.
