xcdroast errors

xcdroast errors

[Rei Shinozuka]

i've been using xcdroast for years on my thinkpad, but it consistently
reports errors duplicating disks on my new desktop.  i was trying to duplicate 
an ISO disk.  i tried several input disks (as well as isos on my
hard drive) and many output blank disks, both CDR and CDRW.  

the xcdroast always reports the error 
after fixation, the scales are always 100% and 99% for read and write
and yet there do not seem to be obvious errors in the logs,
plus the newly-created disks mount and look good, and i've even booted
off one of them.

i have tried all sorts of options but the failures are always
the same.

note that when i use mondo, i burn using the same Plextor drive
and the same batch of CDR and CDRWs and these disks are fine (i know,
i've restored my system from them at least twice!)

any ideas?

What is the actual problem you are having? You write about "errors 
duplicating disks" and "failures" ... but you also write that "the 
newly-created disks mount and look good, and i've even booted off one of 
them". This last makes it sound like xcdroast is working just fine, except 
for, perhaps, some warnings that don't really matter. The output you post 
below shows nothing of concern that I can see.

I suppose it is possible that the desktop hardware is too slow to support 
the write speed that xcdroast defaults to. You don't describe the hardware 
so I can't really say, but I've seen that problem with cdrecord here (I 
deal with it by setting the speed= parameter down).. But speed=10 really 
isn't all that fast, nor is speed=4.

Or there might be something odd about the drive itself ... are we talking 
about an ATA drive using the SCSI-emulcation stuff in the kernel, or a true 
SCSI drive? Or something in the kernel ... is it different from the one you 
use on the laptop?

What is the exact error that xcdroast reports?

I do notice that you are (in both instances below) creating disks that 
push, or possibly pass, the 700 MB "official" size of a CD image. Are you 
seeing problems with smaller ISOs or only ones that push or pass the limit? 
If these images are not oversize (I *think* 732495872 bytes = 698 MB, using 
the definition that 1 MB = 2^20 bytes), does cdrecord do any better if NOT 
given the -overburn switch? As a general practice here, I use overburn (I 
run cdrecord from the command line, not through xcdroast) only when needed, 
not as a standard part of the invocation.

I haven't used mondo myself. Does it succeed with the same ISO images that 
xcdroast fails with? Does it use a setting that corresponds to cdrecord's 
"-overburn" switch?

If i am not mistaken, you say you have a problem but you also say i can use 
the disks i make, now i ask is that a problem.??
Anyway, i am sure that what you say happens, so i being a great beliver in 
linux documentation would suggest the following URL's to you.

http://www.xcdroast.org/faq/
http://www.xcdroast.org/manual/

I have never to be honest duplicated a cd as i always keep my iso's that i 
have dowloaded, i will on the otherhand this weekend duplicate a cdrom.

To be clear on your so called problem, just how do you duplicate.?
Sounds silly to ask does it not, BUT, its not if you consider... 

1) One may have 2 cdroms, one for reading and the other for writing,
  (You did not say).
2) Are you duplicating on the fly or do you create a file then burn the    
image.??
3) Only have one cdrom and burn on the fly.??
4) Whats the hardware, not only cdrom(s) but CPU memory, what other processes 
are running, all those things are explained in the above URL's, so tell us/
me...

Things like that tell in answering such a question, if i am to try what you 
are doing then i and possably Ray need to know HOW you do it.

If as you say everything is fine and dandy but all i see wrong is some message 
in a the log from a xcd session, then possably a mail to the address(s) 
mentioned in the above URL's may well give you a better responce than we can 
give you here.

I hope that is clear.

Let me/us know, i will see what happens here if the need arise.

Your issue sounds very familiar.

My solution to a similar problem was to through away the disk I originally had 
problem with after I had bought a new package of disk.

Re: xcdroast errors

[Rei Shinozuka]

just a more complete rendering of the story.  i also built xcdroast
from source and am running version 15 instead of 14, but i still get
what looks like a spurious error:

What exactly are you referring to when you say "a spurious error"? If the 
software neither reports nor logs any errors, where does a *spurious* error 
appear?

Does the CD work after burning or not? If it does not work, how does it 
fail? If it does work, than what are you asking us about?

In looking at your screenshots, I notice that xcdroast reports the ISO 
source image as (I think - the text is a bit blurry so I may be misreading) 
"803 MB / 79:38:16", requiring an 80-minute CD, not a standard 700 MB/ 
70-minute CD. I also note that you are copying a CD from another drive, not 
burning from an ISO, as I had previously assumed.

Are you using appropriate media? If not, cdrecord is probably quitting when 
it runs out of room on the target disk (after a bit over 700 MB, that is), 
not when the ISO image is completedly written. If this is what's happening, 
I'm a bit suprised that nothing -- not cdrecord or xcdroast -- generates an 
error message ... but it's been a very long time since I tried to burn an 
oversize ISO, so I don't actually recall how cdrecord deals with size overruns.

In an earlier message, I asked you if the problem occurred with smaller ISO 
images or only ones that pushed the allowable size. You said you'd test 
that. Did you? To what effect?

If you copy the existing CD to an ISO file, what is its size?

Your earlier message also seemed to say that this hardware worked fine with 
some CD writing software that ran on some version of Windows. If you can 
still run that setup, will it copy the exact same Knoppix CD successfully?

I did check and verified that standard Knoppix ISO images are 700 MB, so if 
there is a size problem with this duplication, it is probably something 
non-standard about the image on the source CD.
