RRB NTPC 2025 Graduate Level CBT 1 Question Paper (25-Mar-2026) (Shift 3)
The correct answer is

Tighten screws evenly and firmly without over-tightening

When mounting a Hard Disk Drive (HDD) in a desktop computer, it is crucial to ensure that the screws are properly tightened to secure the HDD and prevent any potential damage through movement or vibrations. Let's analyze the options given and understand why the correct method is important:

  1. Tighten only one side: Tightening only one side of the HDD is not advisable as it can lead to imbalance and potential damage due to vibrations or movement during operation. Such uneven mounting can cause undue stress on the HDD and may result in failure over time.
  2. Leave screws slightly loose for HDD to move freely: Allowing the HDD to move freely is also incorrect. A loosely mounted HDD can shift during operation or transport, leading to connection issues or potential physical damage. Secure mounting is necessary for the stability of the drive.
  3. Tighten screws evenly and firmly without over-tightening: This option is correct. Tightening the screws evenly ensures that the HDD is mounted securely without any tilting or stress on any one side. It is important to tighten firmly but not overly tight to avoid stripping the screws or damaging the HDD casing.
  4. Tighten as much as possible with full force: Over-tightening can strip the screw threads or damage the HDD case, potentially leading to malfunction. It is unnecessary and risky to apply excessive force.

Conclusion: The best practice for mounting an HDD is to tighten the screws evenly and firmly without over-tightening. This approach ensures a secure fit, protects the drive, and ensures proper operation of the HDD, thereby enhancing the longevity and reliability of the drive.
