We have received two of these failed drives recently in succession. Further clean room examination has confirmed that the spindle stack has detached itself from the motor base and coil. When first handling the drive it becomes quite obvious that this has happened as you can actually feel the pack rattling. Surprisingly we cannot see any physical damage on the media or contamination and fortunately the clamp has kept the pack secure. We would not recommend spinning the drive up in this condition. The only rework available is to transfer the pack into a good Seagate donor as part of the recovery process. Pack alignment is a critical part of this process.
