Very Computer

Output of cdrecord -scanbus was 0,0,0.

I use ASUS 2410 A (24X 10X 40X) CD writer.
I used koncd to do CD writing. Usually I create a directory, copy the master
CD contents in it, and use "Data CD" option of koncd, indicate the newly
created Source directory and complete the CD Writing without
any problem. But if I want to do CD to CD copying , koncd will start, but
will eject the CD with error message 255.
I thought I will do CD writing using commandline using cdrecord. I read the
CD writing howto which said for CD to CD copying give the following command

"cdrecord -v dev=0,6,0 speed=2 -isosize /dev/scd0"
My CD ROM drive is /dev/hdd, cdwriter is /dev/hdc (/dev/cdrom, /dev/cdrom1).
I put master CD in CDROM drive, blank CD in my CD Writer.
Since my cdrecord -scanbus output was dev=0,0,0
I gave the following command
"cdrecord -v dev=0,0,0 speed=8 -isosize /dev/cdrom"
in pure CLI mode (no X). writing began and  it wrote 576 KB of data and
trashed the CD.
Tried it again . Same result.
What mistake am I committing?
Pl help.

dd if=/dev/cdrom of=/tmp/temp.iso bs=32k
(wait for it to finish)
cdrecord -v dev=0,0,0 speed=8 /tmp/temp.iso

Please note that this *won't* work if the source CD has copy-prevention
*or multiple sessions on it.  That's when you put the source CD in
the CD-RW, then do "cdrdao copy --device /dev/sg0".  HTH, use

CD burning.

Also IDE doesn't work very well copying between two devices on the same
channel.  You may find your buffer doesn't drain so badly if you
transferred your CD-ROM drive to primary slave (/dev/hdb).  Doing this
could reduce your hard drive to a crawl if your CD-ROM doesn't support
ATA-100 (or possibly 66).

Alternatively you could just copy to the hard drive before burning to the
CD.

Styvaen.

Everything else looks normal to me.

You may also want to check out the following CLI options,
minbuf
fs
burnfree (if its applicable to you)
debug

You may also want to post to comp.os.linux.hardware to get more
response. Gl.

One recommendation is to put your source data on a different IDE bus
than your CDRecorder is on, just to avoid this bus contention issue. For
you, this might mean moving /dev/hdd to /dev/hdb.

Sorry to say this again, pls dont crosspost, if you do ( which is ok
here), specify the Followup-To Newsgroup like this,

Followup-To : comp.os.linux.misc

(make it neutral without any distro specific ;) )

Now, you can see, there is already one posting missing in other two NGS
:(. This is exactly what we want to avoid.
