Howdy...
 
After all these years ...I'm conditioned to save, save, save.
I do ...almost 100% of the time (yeh, I still forget once in a while)
Now a New problem for me...
 
SONAR X2a just crashed ...it wiped out two 2 files (versions) I had previously saved...
Both saved files had today's time stamp.
 
The original version of the project was created 3 days ago ...it survived the damage.
 
I had 4 vocal harmonies perfectly balanced ...several dub kicks all working in conjunction with each other sonically together to create a very nice, crunchy beat with lots of "open" space for the bass, choirs, etc...
 
I'd like to write a litany of all the foul things in my brain ...but that won't help.
I've seen reports of this but never yet experienced a complete wipe out like this one...
 
Anyone ever find "lost files" in a circumstance like this?
I did the hard disk searches...

Ouch!  What are these "files (versions)" you mentioned?  Regular "projectname.cwp" files?  Or the actual version files: "projectname.cwp.datetime"?
 

When I begin a project, I'' save various versions such as <filename>.xxx v1 ...v2 ... or perhaps A, B, C and so on...
The SONAR X2a project usually winds up with at least 3 versions at varying stages of recording, mixing, etc...
 
In this case there were two versions saved today of the same file.
Usually ...when a version crashes ... it is not uncommon to discover it has been deleted (through what procedure I do not know)
I have always been able to go back to a previously saved version and rebuild the mix as it was when X2a crashed...
 
This time ...NO
 
For me ...this is an unusual experience.

I'm not sure I understand your versioning process.  To clairfy: you are NOT referring to the versions Sonar automatically creates "projectname.cwp.datetime"?
 
From what I gather, you are manually saving multiple versions via "Save As"?  And then you change the file name after the .cwp?  e.g. mysong.cwp.ver1 or mysong.cwp.A

It does seem extremely unusual that a file that has already been written to disk would be deleted. I am sure you have checked the Windows event log for any unusual entries. While I do not believe it to be a factor is this incident you are running without write caching enabled (the default) in Preferences > Audio > Sync and Caching

I found the "missing" files!...
Searched in a different way...
 
NOW...here's the fun part ... I just discovered a re-createable circumstance...
 
I was adding Boost 11 instead of using the concrete limiter... experimenting with different mixes...
 
Boost 11 froze the program
Then when the program recovered ... there were instances of Boost 11 and X2a crashed.

If you can reproduce a bug you should submit it.

Well... after refining searches ...I did find the files intact.
 
Operator error on the deletion of files...
The addition of Boost 11 "after" the ProChannel in the Master remains something of a problem ...but all is OK since I do not use that plug much any longer in the editing / finalisation process.
 
Thanks for stopping by!
 

I didn't think Sonar would have lost your files. Do you have autosave on? 

I was confused about the whole "search" thing. If one uses per-project folders, all the files related to a project would be in one directory with very few entries and an audio directory beneath it.
