In some client’s pc,like windows10 professional edition.
After install our minifilter driver,when creat/rename file in C drive or F drive,will show up error with:Unable to read source file or disk.
But it is ok with D drive or E drive,it means that just one drive has this problem.
Even if I just return FLT_PREOP_SUCCESS_NO_CALLBACK in PreCreate,the problem still exist.
Why?
You have a bug…Could be anything so you need to debug your code (Process Monitor is your friend).
