Sudden power loss or forced system reboots without proper unmounting of ACFS volumes can leave the file system in an inconsistent state, causing metadata corruption.
⚠️
ACFS Software Inconsistencies
Rarely, specific bugs or race conditions within the ACFS software itself might lead to metadata corruption, manifesting as invalid `_ParentID` values.
⚠️
Improper File System Operations
