A classic WD issue where the drive identifies correctly but becomes incredibly slow, eventually freezing the operating system. This is usually caused by an overflowing G-List or corrupted background allocation logs (Module 32). WD Marvel can clear these logs instantly, restoring normal drive speed. 2.
