I expect files throwing this error are toast, but try the blind export to .idml explained here: Adobe Community: InDesign 6 is crashing when attempting to open a particular document. All others are opening OK.
Thank you so much for your help. I renamed those two files. Relaunched InDesign and tried creating a new document and saving it.
I wasn't able to save the document in my external hardrive where the folder containing the "toast" files are located (not inside that folder but just in my hardrive separately). I was able to save it onto my desktop however.
Do you have any suggestions for what I should do in regards to that folder and my external hardrive as a whole?
If I wipe everything from my external hardrive, do you think it will be able to work properly again?
Thank you again for your quick and expert feedback!
Your external drive might be the problem. I personally never store anything but backup data on an external drive because they do occasionally simply fail (internal drives do, too, but usually they give some warning, plus you should have that external backup -- odds are small they'll fail together). I just replaced a 4 gb flash drive that went wonky. I tried reformatting and reusing it, but it failed again immediately.

It's also possible there's damage to the file, but the divide and conquer technique si the fastest way to learn anything.
I get same error message from time to time when working in indesign on i-mac but different DBTmp number (mine was 689466067727). I can export to pdf but can't save the document. I get out of it like this: With the offending document open go to the finder and force quit indesign. Re-open indesign and the document restores and is able to be saved as normal! Don't know how that works, would be nice if it didn't happen in the first place_damn annoying these pooter gizmos back the drawing board I say.
