cdrecord too slow for Life is Good


after burning a few cds on my LG multiformat DVD/rw cdrecord decided
to try the max speed of the dvd writer (contrary to the first few times when cdrecord selected the speed). it now states that 40x is too fast, that fedora cannot do such a thing, and this makes me stranded(and sad).
how do i adjust the burn speed?
help

Couldn't help with the burn speed, but have you considered trying any other app that may support it better? Most OS come with 2 or 3 cdburnapps at least.

cdrecord speed

i still would like an answer to my first question, but:
what other cd burning apps are included with FC3? i have no internet connection on my linux machine so a download is out of the question.

Code:
cdrecord dev=<your dev code> speed=X /path/to/cd_image.img
If you're not using cdrecord from the command line, then you'll need to read up on your application's documentation to find out how you pass a value for the speed option.

Are you actually trying to burn CDs or DVDs at that speed?
Just checking ... ;}

Yeah, the original question isn't completely clear whether it's CD writing or DVD. I'm leaning more to the CD writing, but if it is DVD writing, realize that there's another set of recording tools available for DVD's: dvdrtools. Here's the page on freshmeat.net: dvdrtools

Also note: 1X for CD's in most definitely not equal to 1X for DVD's

cdrecord

thanks amill dark helmet, ill try this

i am burning cd's.
another question which leads on from this is: what exactly is fedora core 3's burning speed limit for cds?
it told me that it could manage 40X but it didnt tell me what it could manage.
also in; "speed = X" doesnt X have to be a multiple of a certain number? (or can it be any number)

I'm not aware of any intrinsic limit based on a distribution.

The speed limit should depend entirely on the hardware you have. The "big players" are the CD recorder's supported speed (99% of the time this is the limiting factor), the speed of your hard drive to retrieve the information to write on the CD, and the speed of your processor to feed the data to the CD burner once the hard drive pulls it into memory.

Recording speed can be any number. That number itself represents a multiple of 150 kilobytes per second. So if you're burning at 5X, the CD writer is putting roughly 750 kilobytes per second on the CD. If you're running at 10X, that's roughly 1500 kilobytes per second.

You'll usually only see powers of 2, or multiples of 5. Very rarely will you see anyone advertise a 37X or 13X CD writer. Actually, you'd probably be hard pressed these days to find anything under 30X unless it's over a year old. And even then...

What is the speeds specified on your drive? I have never heard of a drive that can write at 40X. Most drives have the speed specified in three parts eg. 8x4x32x this is read from left to write as Write a CD-R/DVD-r at 8x writes a CD-RW/DVD-RW at 4x and reads all at 32X. I think you are trying to write at the read speed which simply won't work.

I dunno, I've got an old CDRW drive in another computer here and it's 32x12x40x and thats CDRxCDRWxCDROM. My DVDRW in the current computer doesn't have speed on it so I can't comment from that.

I must be getting a little behind in some of my hardware.

Can you get CDs the won't shatter in the drive at that speed? Nah that doesn't really suprise me, my 32x burner would be at least 2-3yrs old, probably more.
