Check cable connections Ensure both SATA data and power cables are firmly connected. 2. Try a different SATA port The current motherboard port may be faulty. 3. Try a different cable SATA cables can fail. Swap with a known working one. 4. Check BIOS detection Enter BIOS and check if the drive appears in storage devices. 5. Listen for drive sounds Spinning sounds indicate power. Clicking indicates failure. ## Guided Troubleshooting Answer these questions to narrow down the issue. Does the drive appear in BIOS? YesNo Is this a new drive or was it previously working? YesNo Can you hear the drive spinning? YesNo ## Possible Causes Loose SATA cable Very Common Cables work loose over time, especially during moves. Faulty SATA port Moderate Individual motherboard ports can fail. Drive not initialised Common New drives need initialisation in Disk Management. Drive failure Moderate Mechanical or electronic failure prevents detection. BIOS settings Less Common SATA mode or port may be disabled in BIOS. Power supply issue Less Common Insufficient power or faulty PSU connector. If the cause requires professional attention, see [Get Desktop PC slow performance fixed](/repair/pc/slow-performance). ## Self-Fix Instructions Safe steps you can try at home. 1. ### Reseat all cables 1\.

Right-click Start > Disk Management. 2. If the drive appears as Unknown/Not Initialised, right-click > Initialise Disk. 3. Choose GPT for drives over 2TB. 4. Create a New Simple Volume and format. 4. ### Test in another PC 1\. Connect the drive to a different PC. 2. If detected there, the issue is with your original PC SATA port or cables. 3. If not detected anywhere, the drive has likely failed. ## Safety Warnings - Always power off and unplug before working inside the PC. - If the drive contains important data, do not initialise or format it. - Clicking drives may have recoverable data.
