 |
|
Hi.
I've got Gentoo Linux with KDE 3.0.4 running on several machines (both x86 and PPC), but only one with a CDR drive (my mom's main machine). When she wants to copy music cd tracks, either as WAV, MP3 or Ogg Vorbis, it's so slow that she gets bored after just a couple of tracks.
i checked it today, and everything seems ok, using ide-cd for both the CDR and CDROM drives, the tracks are eventually read, but its really slow, you can actually hear the mechanism going down between reads.
should i disable ide-cd for the CDROM drive? i think the disc to disc copy wouldn't work this way... |

| It sounds as though DMA may not be enabled on your IDE device(-s). You might try compiling support for your IDE controller into your kernel if you haven't done so already. |

| DMA is enabled on the kernel IDE driver, but i think the ide-scsi won't use that. |

I think what the above poster meant, was something in the direction of
| Code: | | hdparm -c1 -d1 /dev/hdc |
while using the device in IDE-mode.
Also, a few programs allow you to select ripping speed, for accuracy/speed. Is CD-Paranoia-mode used?

i'm mostly using KDE's Audio CD IO-Slave, just dragging the music icons to a directory. How paranoid is it? |

The fact that it spins up, and spins down again indicates that it fills up a buffer, and waites to do some more. Perhaps it is set to rip at 1x? I am not familiar with the KDE method, but I have used a program called "rip" before. It's very simplistic, but it's not a GUI application. (emerge rip)

Actually, it seems to work fine for me. After I put support for my VIA chipset into the kernel I never have to run hdparm on any of my IDE devices, and the ide-scsi devices I have are running at 33.3MB/s with UDMA enabled. You can check to see what your devices are doing by running "cat /proc/ide/chipset_name". |
