    Hello,

    we've trouble with strange file corruptions on LattePanda Boards 2G/32GB.

    We using LP on industrial applications by measuring different aspects of air quality. Our application writes the measured data of the sensors to logfiles.
    As OS we're using Windows 10 Enterprise LTSC (drivers from LP Github repository), formerly known as IoT with activated file based write filter UWF to protect the OS against power loss.

    Currently we've about 20 of this devices in our development and production sites and all of them have the same problems.

    Our logfiles, txt format, got corrupted with some different garbage. So far we try in vain to narrow down the problem. For example, we wrote small test programs in .NET and Labview that simply write the same text into a text file. Also this files got corruption.

    To get you a picture of this corruption, here some small sections:

    It seems that sometimes the storages system produces wrong file references or sector links on the ssd. It's an absolutely strange behaviour and not reproduce on demand. The problems appear very sporadically, but on all devices. Sometimes we've such error one a week, and sometimes every day. But it seems only on files that are written over longer period.

    On about 5 devices with also have some sort of NTFS corruption detected by OS and chkdsk will become necessary.

    Could this be a problem with Windows 10 Enterprise LTSC on the LP?
    We've tried to reproduce it on a LP with the preinstalled Windows 10 Home and so far nothing has happened yet. But Win 10 Home contains no UWF and seems less suitable for IoT devices.

    Btw, the same OS and programs on another Computerboard doesn't show such problems.

    Any ideas on this?

    Thanks.
    regards
    Markus
