The 3.5-inch hard disk drive (HDD) bracket that is used in the Sun Server X3-2 incorporates a spring-loaded metal grounding strap, which is located on the right side of the HDD bracket. A deflection in the grounding strap can cause the strap to catch on the server disk cage, which can further damage the grounding strap. Once damaged, the grounding strap cannot be repaired and the HDD bracket must be replaced.
Before installing a 3.5-inch HDD into your system, visually inspect the grounding strap to ensure that the end of the strap is seated correctly in the HDD bracket. See the following figure for an example of a grounding strap that is seated correctly.

If the grounding strap is not seated correctly, or is protruding past the outer edge of the HDD bracket, the HDD bracket should be replaced. See the following figure for an example of a grounding strap that is not seated correctly.
