From everything that I remember, the .4DD file is where the marker was stored. If it was put in another file somewhere else on the hard drive it could get lost or not stay connected to the .4DD file if you moved it around to a different machine or location. I also seem to remember that Paul Carnine — remember him and his DataCheck program — had reverse engineered the location of this flag in the header area of the .4DD. DataCheck had an option to just clear this flag. > If I run a repair on the datafile 4D crashes. I have tried to run the repair > several times and it crashes at the same spot every time. That indicates serious damage to the data file. Record allocation tables ore bitmaps are damaged. Time to recover by tags. > I ran a repair on the structure and it failed reporting that the flush did > not complete. The structure file is actually a special 4D data file used to store all the methods, forms, menu bars, etc. So it can also fall prey to crashing and the cache not finishing flushing. I’ve had this happen to me once in the past. > Finally I ran a repair on the datafile using record headers and it looks like > I am back in.

That’s a Miyako or JPR low level detailed information. I can only relate what I’ve heard or learned over the years.
