Simultaneous CD Burning
 
A friend of mine managed to get authorization to install Linux on one of our old P2 350s. The idea is to make a system that can burn half a dozen to a dozen of CDs by pressing a buttong, or entering a simple command.

Thus far we've tried several how-tos and scripts. Has anyone gotten two or more CD burners to burn the same data simultaneously with RedHat?

i know k3b (as of version 0.50) is capable of burning two cds at the same time but not sure about more than two...

Yeah, you cant burn more than 2 cds at a time without serious issues on a modern processor, let alone a P2.

What you want to do is pretty impossible.


If you want to burn cds one after the other, thats possible.

Yep, impossible... unless you make some linux controlled lego technic device to auto change the blank and burned cds ;)

Well, my coworker is pretty sure that his inability to write to more than one drive at a time is a limitation of IDE. He's pretty confident that on SCSI or Firewire it would work. Care to comment on that? Are we wasting our time pursuing this route?

Is there some other hardware modification we might use to achieve this? Perhaps some sort of adapter that, for example, had one I/O cable to the IDE buss, and several OUT, one IN cable going to multiple identical CDRW drives.

Basically the idea is that with identitical drives recieving identical data simultaneously we would thus be able to burn CDs simultaneously.

Thanks for the info on the dual CD burning option though, we'll definately look into that.

The limitation isnt in the Cdburners, its in your processor.

CD burning is a VERY intensive task, and burning lots of CDs at once will producs lots of coasters.

Hell, surfing the web and burning can do it, and on a 200Mhz processor, its IMPOSSIBLE.

You'd need at least a 2.4Ghz to attempt it.

DrOzz 09-08-2003 10:34 PM

hey i am not worried about what processor you need, he asked a question and he got the answer...and that is that..
you say you can't
proud says impossible...
and i just wanted to point out, that you can and that its not impossible..

Proud 09-09-2003 04:38 PM

I meant more than 2 cds at a time would be impossible/limited by the physical fact that you only have 2 cd writers to take and burn 2 cds at any given instance :P

If you have a large number of writer drives connected or accessable in some way (network shared?) then multiple instances of your burning app should be able to do it on a powerful system. Using the command line and a script would probably be more reliable than having X + Kde apps running.

onu,

Any success? Yours is the only post I could find at LinuxQuestions that addresses this subject. I'm wanting to do the same, copy a master to multiple burners at the same time.

Would really be interested to hear what results you had.

Thanks so much for any feedback!
