Overcoming CDRecord problems

[I.M. Weasel]

I am trying to get CDRecord working on my machine. I am using an older version of cdrecord, version 1.1.3. With any of the newer versions, including the pre-compiled binary for rhapsody, I get a killing error.

I am following the steps/backtracking from this post.

Everything is ok ,except for the second to last line:

WARNING: padding up to secsize.

Even though I am using a different mac , I am still getting that same warning in the output that I got in previous linked post. It creates Coasters with 1 audio section as the second track, 5:02 in length. Does anyone know how to prevent this padding?

Does anyone know how to prevent this padding?

-nopad should do it.

[Ex-Cyber]

The "padding up to secsize" warning typically means that you're using the wrong mode for burning the image that you have. You can suppress it with -nopad, but what you really need to do is figure out why your mode is mismatched. If cdrecord -help says:

-xa Subsequent tracks are CD-ROM XA mode 2 form 1 - 2048 bytes
-xa1 Subsequent tracks are CD-ROM XA mode 2 form 1 - 2056 bytes

then you probably want -xa instead of -xa1; Joerg changed these options around at some point and versions with the new options give wrong results with all the old Dreamcast burning guides.

You probably already realized this, but I want to just say that -nopad will probably not produce a working disc. The data is not going to be in its correct sectors, i.e. 8 bytes of sector 2's data will be in sector 1, 16 bytes of sector 3's data will be in sector 2, etc.

This may not help, but have you tried using cdrecord 2.x? More drives are supported I think. I've used that version in the past without any issues. These were with Apple stock drives. Not sure about 3rd party. I'd send you a pre-compiled binary, but that machine has long died.

edit: I just followed that link to the old thread. I completely forgot that we have been down this road before and there wasn't a resolution.

[I.M. Weasel]

I have tried both -nopad & -pad with padding up to correct size, and neither produced a working disc.

Although I will try to switch the xa modes to make it work.

I used the precompiled binary for OSX rhapsody in the cdrecord gopher site, and i get that same error I got last time 'SEGMENTATION FAULT'. Same with the compiled version 2.0.1 that you sent me, way back when the original thread was made (gets the same error).

I'm glad you posted, I was gonna hunt down your email to try and get your help.

In that thread I used an iMac with a stock cd-rw drive, this time i'm using a g4 b&w with a pc standard DVD-RW drive. I still get the same error with -xa1.

As per the info in toast, it is a iso file size of 2048 + (12 byte subheader) = 2056.
This is the output I get with -xa2, they are defined -xa1 & -xa2. I actually does not burn the disc at all,with either the first or second session. ./cdrecord: Undefined error: 0. write_g1: scsi sendcmd: no error .... is the main error that is generated.

And it will have Trouble flushing the cache @/after the 2nd session.

Could It be from the mkisofs creation not being perfect? Toast recognizes the iso created from the below commands as a XA track just fine..

Code: Select all

mkisofs -C 0,11700 -V INDUCER -l -d -o ~/temp.iso Inducer
( cat Ip.bin ; dd if=temp.iso bs=2048 skip=16 ) > temp2.iso
isofix temp2.iso 11700 /mac

[|darc|]

You need to use -xa, not xa1/xa2.

Or change your mkisofs command to output at a sector size of 2056 ("-secsize 2056"?) and then use -xa1.

[emptythought]

You need to use -xa, not xa1/xa2.

He's using 1.11x. I don't even think -xa is a option in that version, like Ex-Cyber said, Jorge changed the commands a little. He should be using -xa1 for 2048 size sectors for his version...

I'm not sure if you really need isofix to make a Mac ISO. Older version of CDRecord should also start the second session at 11702...

But I've been doing some Googling. It looks like you also need to unmount your burner before you write the second session.

cdrecord cannot access non-blank discs on its own. These discs are controlled by the Mac GUI. To disengage the CD from the Mac GUI, you have to dismount it, either using Disk Utility or the terminal. With the terminal, you need the disktool command and the bsdname of the mounted CD-Rom. To get the bsdname, try the df command and look for the line /dev/disk[?]0 in the output. The disk[?] will be the bsdname, i.e., /dev/disk2s0 would provide a bsdname of "disk2." Unmount the disk as follows:

Code: Select all

disktool -u disk2 0

Any time you want to access a non-blank disc using either cdrecord or one of its sister tools, you will need to use this disktool command to disengage the disk from Mac OS X and unmount its image from the desktop.

Sorry, I misunderstood Ex-Cyber's post to imply that he was using the newer cdrtools.

[abydos1000]

Yes, making sure the disc is unmounted is an important point. I assume he is using the directions I posted in the original thread which I think had that command in there. You can also go to the system preferences and and set the finder to ignore inserted blank discs, but that only works for the first track. Once something is written to the disc, the finder will mount it.

I'm too busy the rest of the week to look into this again. Maybe this weekend. From the original thread, I can't see why I was getting working discs and he was getting coasters. Honestly though, I haven't burned a disc for the DC in over two years.

Ok, I thought xa and xa1 were the same. 1.13 only has xa1 & xa2, no just 'xa' option. I would much rather use 2.01 or cdrtools, but every precompiled binary i get of those versions does not run of my machine. (see first post).

But I might give that a try with mkisofs. I have tried to deviate from the regular 3 line comands in the past (that i posted above), for making DC cd's but little has worked.

disktool -u disk2 0

I have been using disktool to unmount the cd after the first burn. I didnt mention it earlier, because I cant even get the first session to burn right. but yes, I use disktool inbetween.

I know it has been awhile, but there is one thing in particular I need to know. On page 2 of that previous thread, you showed a step by step successful breakdown of your use of cdrecord. What I need to know is what ISO's did you use in that? ISO's made by Mac Dream Tool? ISO's made through terminal commands? or ISO's made with another mac booting program (my regular selfbooter, weepels)?

[|darc|]

Have you tried compiling your own version?

Given that was 3 years ago, I can't give an answer with 100% certainty. The source of the images was likely one of the following:

1. Images made by MacDreamTool (what ever was current in 2004)
2. Images made by CDIRip from a DiscJuggler Image (e.g., something from Dcevolution).

I suspect it was #1, but I can't be certain. However, those were the only images I ever messed with.

As for compiling, I used Fink to compile 2.X from source way back. However, IM doesn't want to install that. He should be able to find the source code, and I think one can dig around Fink's web site to see if there are any dependancies before building.

[Calavera]

Does anyone know how to prevent this padding?

-nopad should do it.

I actually had this problem when I was on a Mac and that actually did help me produce a working disc. Your experience may vary of course.
