[redhat 9]whenever i put a cd in my cd rw drive it will cause my computer to freeze (i will have to do a cold boot).[/redhat 9]

Code:

[schneidz@lq]$ uname -a
Linux lq 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 i686 i386 GNU/Linux
[schneidz@lq]$ dmesg

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).

thanks elf,

here's my hdparm output:

Code:

[schneidz@lq]# hdparm -vi /dev/hdd
 
/dev/hdd:

i'll try to disable dma and post if that works.

shutting off dma worked but i haven't tried to write yet

schneidz · 09-01-2005, 09:50 AM

now the same thing happens when i try to write. unfortunatly, using the burn bottun on 'nautilaus' or using 'gnome-roast' doesn't yeild any output messages,

any ideas?

Half_Elf · 09-01-2005, 07:16 PM

hmmm sound like broken hardware to me... do you have dual boot? have you tested this drive on another system?

schneidz · 09-02-2005, 11:04 AM

yeah i duel boot.

it works in m$ windoze.

schneidz · 07-10-2006, 01:31 PM

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,

I had a similar problem, I tried different media and it worked.

schneidz · 07-11-2006, 11:40 AM

thanks kdb4, i tried multiple types of media during the last year and it would freeze my computer indiscriminately.

anyone else have similar problems?

schneidz · 07-17-2006, 03:44 PM

is there a way to trace what it is getting stuck on upon inserting a cd?

schneidz · 07-21-2006, 02:29 PM

was able to iso-write 'dsl' with it in knoppix live-cd.

schneidz · 11-30-2006, 09:41 AM

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,
