Re: cdrecord dies on CD to CD copy
Joerg Schilling [EMAIL PROTECTED] advised: I switched to using dd if=/dev/scd0 bs=64k as the source of the pipe and the buffer reported being 100% full all the way; it worked fine, additionally. Don't do that, cdrecord does the job better. In any case, it is a good idea not to copy without image. Definitely agreed. I have a situation which requires burning from an NFS mounted ISO image, and that's essentially the same problem as read and burn copy. I write at low speed and use a large fifo, but I would keep a copy of the image on local disk if I could. On the other hand, there is something to be said for NFS, someone else buys the storage and must do backups! That covers a lot of inconvenience. -- -bill davidsen ([EMAIL PROTECTED]) The secret to procrastination is to put things off until the last possible moment - but no longer -me -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

cdrecord dies on CD to CD copy
Hi, I'm using a vanilla CD-Rom + HP CD-R IDE setup through ide-scsi and sg on a Linux 2.4.7 box, and I've noticed the following: when copying to /dev/scd1 (0,1,0) using cdrecord -v dev=0,1,0 -isosize /dev/scd0 At the end of scd0 cdrecord reports an error (can't copy now, but the gist of it was input stream ended) and fails to fixate the disc. Basically, all the data from the CD has been read, but since the reading child dies, I think cdrecord notices it and dies on the spot. I would very much like to hear a report that this works - what happens when the source CD ends? No error message? The CD recorded was, of course, lost. So I attempted (successfuly) to copy using the crude: cat /dev/scd0 | cdrecord -v dev=0,1,0 -waiti - And this worked, though it reported fifo=0% through 99% of the process. Is there a way to do this in a more intelligent fashion? TIA, folks.

Read README.copy README.verify I'm afraid I wasn't logging with the proper facility, so the error is lost. It's basically an error reporting the input stream ended. From what I can grasp from README.copy the problem is probably the two unreadable sectors at the end of the disk, perhaps combined with read-ahead on the device.

Re: cd to cd copy
"Mike R. Cannon" [EMAIL PROTECTED] asked: Is it possible to burn a cd from a cd with out first making a iso? I use these commands to produce a cd: mkisofs -r -J -V cd_name -o cd_image img/ cdrecord -v speed=4 dev=0,0,0 -data cd_image We just received a new machine to set up as a universal cd writer. I want to put linux on it, but others want windows. Biggest complaint was they would not be able to simple copy cds, the would need to make iso first. Is there a way to just copy without making an iso. First, you just want to copy data off a data (mountable) CD, the mkisofs isn't needed. You can use dd or sdd to pull the data. More to the point, unless you have one of the burn proof CD writers, you will find that any slowdown in the incoming data which results in the buffer going empty will also generate a bad CD output. So the read and burn is certainly more reliable. You can run the output of a raw reading program into cdrecord, but the reliability is not as good (and direct copy on Windows is not as reliable, either). Something like: sdd if=/dev/cd1 | cdrecord dev=0,0,0 speed=4 -pad Adjusted to your device names and numbers, and whatever speed you like. You can uncrease the buffer in cdrecord, or drop the speed to improve reliability. For music I would always rip using a good program, then burn. -- -bill davidsen ([EMAIL PROTECTED]) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Hi, I use cdrdao to make 1:1 copies: cdrdao copy --paranoia-mode 3 --on-the-fly --device 0,0,0 --driver generic-mmc:0x10 --source-device 0,1,0 --source-driver generic-mmc:0x0 --buffers 30 paranoia mode is for Audio CDs on the fly is self explanatory and you specify the source and target writers and the driver to use (if the CD driver to use is not autodetected) buffers is to give it a bigger buffer. If you don't want to take care of all the options you can also use gcdmaster (former xcdrdao) that comes with cdrdao. It currently uses gnome. Of course I'm sure you can use a pipe or use some n-curses base programs that use cdrecord and simplifies things a lot.

Well, I have write a simple program could copy "CD-DA", "mode 1", "mode 2", "mode 2 form 1", "mode 2 form 2", "mixed mode", "multisession"... "VCD 1.0", "VCD 1.1", "VCD 2.0", "SVCD", "CVD"... directly. Are you interesting in my program? Would you want to try it? For now, it only run on linux smoothly. But I have to say very sorry about I could not open source codes. And I don't know where I should put it on. If anyone is interesting in try it, I can mail the binary to him. The program I named it "cdcopy". It links Schilling's scsi library, all other parts are coding by myself. I don't know much about copyright. But, could I just open binary not source codes?
