Hi,
I 'm running Debian Woody and I have ide cd writer LiteOn 40x24x10. For
burning I use scsi emulation. All modules like ide-cd, ide-scsi, ... are
compiled as modules.
But copying from cd to the hdd is very slow, approx 2.5MB/s and
processor usage is 100%(like PIO??). I tried to use hdparm to enable
ultra dma, but using it on /dev/hdc , /dev/cdrom, /dev/scd0 I received
"device not supported". I tried also to run hdparm in rc.d before
modules are loaded, but I got another error.
Is there any possibility to enable udma on cdrom drive using scsi
emulation? Or it is possible before copying from cd to disable scsi
emulation and have "ordinary" ide cdrom, on which I can run hdparm?

Thank you for any hints

R.Pencik
