After installing a new hard disk, the DVD drive no longer works. What should you check first?

1. The software drivers

2. Make sure the DVD drive cables are connected

3. The power supply

4. The BIOS settings

The correct answer is: Make sure the DVD drive cables are connected

When dealing with hardware issues such as a malfunctioning DVD drive following the installation of a new hard disk, the first step is to ensure that the physical connections are secure. Checking that the DVD drive cables are connected correctly is crucial because the installation of a new hard disk may inadvertently disturb the existing connections within the system. It's possible that during the installation, cables were disconnected or moved out of place, either directly affecting the DVD drive or causing other components to shift and misalign. Verifying that the cables are firmly connected rules out a simple connectivity issue and can quickly point you toward further troubleshooting if needed. In contrast, while examining software drivers and the power supply may also be necessary later on, they are not the first points to check since the immediate physical connection often provides the most straightforward resolution to such issues. BIOS settings would generally be considered after ensuring all hardware connections are intact, as they typically pertain more to the recognition of devices rather than their operational status following physical connection changes.
