look like the dma mode of your cdrom is too high... post the output of "hdparm -vi /dev/hdd". For now, a fix could be to turn off DMA (hdparm -d0 /dev/hdd).

i just installed fedora-core-5 hoping that this cd-rw would exist in the driver database. but when i put a cd in the drive it would do the same thing (i had to burn the iso's using m$ windoze me ).

what can be done to get this cd-rw to work in fc-5?
any help is appreciated; let me know what info i need to post.

thanks,

hi i went back to rh9 so the cd-rw still isn't working.

i deleted my m$ windoze partition so i have no ability to burn any iso.

unfortunately, since my dvd drive and my cd-rw are connected to the same ide cable i get a lot of buffer underrun coasters if using knoppix live-cd.

is there any hope for me to be able to use this cd-rw drive ?

thanks,
