[Grml] Slow access to CD

Hi

My CD accessing speed is extremely slow.

For "cdrdao read-cd", which normally takes 5~6min, takes 5 times as long:

real 24m54.889s user 0m0.004s sys 0m0.016s

For "vcdxrip", which normally takes same as "cdrdao read-cd", 5~6min, literely takes forever:

#extract[avseq01.mpg]: 148720/354829 (42%) ^C

real 83m17.571s user 0m0.000s sys 0m0.012s

Everything has been fine in Debian Sarge. What could be wrong?

PS. I've turned dma on for my CD:

% hdparm -d1 /dev/hdc

/dev/hdc: setting using_dma to 1 (on) using_dma = 1 (on)

please help

thanks
