- The Component: Multi-bay desktop enclosures (ThunderBay 4, ThunderBay 8) utilizing SoftRAID, OWC’s proprietary software-defined storage management layer for macOS.
- The Failure (Driver Architecture Breaks): Unlike hardware RAID enclosures that manage arrays on an internal chip, OWC ThunderBays rely on macOS kernel extensions or system extensions via the SoftRAID app. When Apple pushes a major macOS update, the operating system's security architecture frequently blocks the SoftRAID driver.
- The Symptoms: The volume completely vanishes from the desktop after an OS update. Opening the SoftRAID application may show the array as "Degraded" or "Missing Tiles," even though all physical hard drives are completely healthy. If a user tries to rebuild the array while the driver is unstable, it can result in total directory corruption.
