I work in AutoCAD 2014 but saveas 2004 as I exchange files with a lot of older CAD users. It seems that they can open any file I save in 04, however Xrefs that have been loaded in my drawings appear to be getting corrupted. The 04 users can not open them until I open them in 2014 and save them. They are easy to spot as they lose their thumbnail preview in Windows Explorer until they are saved again. It appears as if the Xrefs referenced in my drawings are being saved as 2014 even though I am not editing them. How can I prevent this. It didn't seem to occur until I upgraded from 13 to 14.
I have Xrefs set to Demand load Xrefs "Enabled with copy", with Retain changes and Allow others to refedit both checked. If that makes any difference.

At the moment you modify the XRef it will be updated to the current drawing format.

That is not the way that should be default. You work with a current software and try to save it like a software 10 releases before. That can be compared to take a glass, push it to the floor so get's broken to 1000nds bits of glas (save new elements back in a way that 2004 can do anything with it) ... and when opening in 2014 (as you want to have the full new properties for all objects) AutoCAD needs to take the puzzels and tinker them together. It's not only a lot of time that makes saving and opening slower, you also risk that some elements are not reconstructed without errors.
If you have people that work with older AutoCAD releases then they can install Autodesk TrueView (free to use, >>>download<<<) to open your files and save them back to an older release. But I would really avoid to have my working files saved back!

In a perfect world everyone would be using the latest version. But that is not an option here. Also in a perfect world AutoCAD would not be writing changes to files that are only loaded into a drawing read only. I am not edting these files, they are Xrefs in the drawings I open. They are somehow getting currupted in the process. So does anyone have any real answers here or should I just go back to using 2013?
>> Also in a perfect world AutoCAD would not be writing changes to files that are only loaded into a drawing read only
For me AutoCAD does not change the content of the XRef'd 2004-DWG as long as I don't modify it (as I wrote in the above answer).
With other words or steps:
- I create a drawing A.DWG in DWG2004 format (save and close it)
- I start AutoCAD 2014, create a new drawing B.DWG, start command _XREF to get the A.DWG referenced and displayed.
- I save this drawing as B.DWG and close it.
- I open the A.DWG ... it is in DWG2004 format, it is not rewritten (filedate has not changed after step 1)
and I can open it in older AutoCAD releases.
So it works for me as it should.

In a none perfect world AutoCAD has to play puzzle everytime to save your current geometry into a technology that is 10 years old.

I guess we should be able to reproduce it to find answers, at the moment I have no workflow to reproduce your issue
Can you describe what you do (exactly) to get that problem or is it depending on specific drawings (so can you upload one of those)?

I open a control panel drawing containing multible Xrefs of the internal parts. Check a dim and close the drawing without saving it. Later another user complains that a few of the Xrefs in his drawing wont load. When viewed in the file open dialog box, they lack a preview image, but open normally using 2014. I open and save the drawings and the other user can now load them.
I didn't have this problem in 2013, it only started after I began using 2014. The PC and OS is the same.
Your close; I open file XYZ containing 10 Xrefs, I pan and zoom and then pull a dim from two points. That is all I needed to know and i exit without saving. Coworker opens file ZYZ that contains 7 of those 10 Xrefs. 3 of them don't load. They instead display the path in text format as you would with an invalid path. The 3 files have not been opened individually, but are common Xrefs to both drawings. When viewed in AutoCAD the thumbnail preview is gone, but I can open that file individually without error message. I do a hide on it to give it the preview I want and close saving the file. Coworker can now open file ZYZ and his Xrefs load properly. If the coworker tries to open any of the 3 Xrefs he gets an invalide file error message.
It's not consistant as I have tried to reproduce the error, but have not managed to do so since last time.
I'm not sure to really understand file XYZ and ZYZ and what AutoCAD version another employee had who opened a drawing that had 3 or 10 or 7 XRefs that are together referenced in XYZ as well as in ZYZ.
But one option you might try: look to sysvars XLOADCTL (>>>details<<<) and also XLOADPATH (>>>details<<<) to avoid that your referenced files are cached locally. Maybe that avoids some issues (hopefully). Check that on all workstations!
>> That is all I needed to know and i exit without saving
If you closed your drawing without saving it ==> look to the referenced files ==> have they changed their "modified-date/time" now?
