CH2014 Posted July 27, 2018 Share Posted July 27, 2018 Hi, I have a DF application running perfectly on a Windows 10 laptop. There is a Persist directory that contains 104 DAT files (each file is set to hold 3144960 values) file size (approx) 47.9mb each. The application was moved to the clients HMI (also Windows 10). After about a week of random use, the DF application starting to crash on startup (including Daqfactory.exe itself). I was not able to gain access to the DF Command/Alert utility to see what the error might be. However, I eventually determined that there was some sort of corruption within the Persist directory. i.e. After deleting the Persist directory and then allowing the DF to recreate the Persist directory and the 104 DAT files the application started working again. Some questions: - 1. What can cause the Persist file to become corrupted? 2. Is there any way to pinpoint the corrupted DAT file (as it seems a bit drastic deleting all the DAT files)? 3. Is it possible to repair the DAT file (as potentially quite a lot of data could be lost)? Quote Link to comment Share on other sites More sharing options...
