Creo Schematics (and it sounds like Creo Parametric) periodically write to the database in the local workspace when the computer is idle. If the computer is in sleep mode or the hard drive has shut down, it may not write the information completely and corrupt the database. I have been told that this is an issue that Schematics attempts to write the data but that the hard drive is not ready and misses some of it. Walking away from your computer can trigger this.
Can Schematics be updated to look at the hard drive and sleep status before trying to write data to the hard drive, or verify that it was written correctly?
The recommended solution is to change the computer settings to not allow windows to shut down the hard drive or let the computer go into sleep mode automatically. Many companies have group policies that users cannot change. We create a file that indicates that the computer has been used for Schematics that our IS queries when they are doing a group policy update and those computers get the unique settings.
This worked well when everyone was using desktop computers.
Now that most of the people (all within a couple years) have laptops, it eliminates the laptop going to sleep when the top is closed. This is ok when someone is headed to a meeting but causes overheating and battery use if they leave it closed for significant amount of time.
