Up to 70% of drives that are returned to the drive manufacturers are fine. Many can be powered back on and, with no additional effort, pass all diagnostic tests. Many of the remaining “failed” drives can simply be reconditioned by recalibrating the heads, rewriting the servo tracks and performing a low-level format of the drive. The bigger fear is that the drive with excessive vibration does not fail right away and causes the two adjacent drives on each side to fail, thereby causing a complete RAID failure.”]
