I have looked everywhere and not found the answer to this.
 
I keep "losing" audio files. Here is what I think is happening....
 
I record 28 channels at my band room during practice. I make a CWB and bring them home, where I edit. At home, I also record like crazy just playing around in the studio -is it possible the numeric ( Track 1 (Bounced, 270).wav is duplicated in the CWB I bring back and screwing things up? I am running a HDD to HDD transfer 3X  a week in the meantime so I will always have a copy of what gets eaten.
 
Whats the best practices for CWBs if you move between locations a lot? Is it possible this is something else? I am an IT guy, this shouldn't be that hard, but its got me stumped.....for now.

Personally, I wouldn't bother with CWB files.  Just make sure you choose "Copy all audio with project" and save each project in its own folder.  That way, the audio will be stored in a subfolder of the project folder so everything will be self contained with no possibility of filenames clashing.

If you new recording back at home is in a new project, then it won't affect any audio already on the disk at all.
 
If you open an existing project then record into existing tracks, if you save the project, next time you load it, it will be in the state it was when you saved it.
 
If you want to record new stuff without a risk of affecting the existing band tracks then I suggest putting the new recordings into fresh tracks. If you need to edit an existing track so some of the content is silent, chop the track into clips and mute (not delete) the clips you don't want to hear. That way nothing gets deleted or over-written.
 
Though I wouldn't use cwb's at all. Like AntManB says, save each project in its own folder with the preferences set to store audio in "per project" folders. Keeps everything together with no risk of losing everything if the bundle gets corrupted in some way.

YUP! I always leave things in project folders and simply create the one going with me or being transferred using Save As, into a new folder, with the Copy all audio box checked, and it's ALWAYS all there (in Sonar's regular format, with the Audio sub-folder populated with all the correct clips), just open it up when you get to wherever you are going, and it will open perfectly fine every time.
 
A nice bonus with the above is that when you do the Save As and the Copy All Audio, it only copies audio clips that are ACTUALLY REFERENCED by the project to the new Audio sub-folder, so it's not carrying a bunch of dead clips around.  That really helps to keep things cleaned up nicely.

I've done plenty of live band recordings, most are 12 - 14 tracks. I too would never use CWB I don't understand where people get that idea from?? .That's like 1998 .  Cakewalks project files ( CWP)  are 100% transferable. 
 
Record your projects to an album folder and date it. 
 
Take it home and mess about and date that too when done. 
 
If more overdubs are needed later at the rehearsal place put the files back on a portable HD and go add new  parts and Date that. 
 
I never delete the dated folders until I'm dead sure I don't need the originals.
 
Always use the COPY AUDIO option and your files will be 100% .
