Fix HDD Detection Issues with an Asus HDD Controller Board

Stable Power and Data Access for Your Laptop Drive

If your hard drive is not recognized, frequently disconnects, or spins up and then stops, the culprit is often the Asus HDD controller board. This essential module connects your internal HDD or SSD to the laptop’s motherboard, providing a secure path for SATA signals and power delivery.
Typical symptoms like boot loops, intermittent drive errors, or unlisted HDDs in BIOS often point to a damaged or loose board. Swapping out the HDD controller board is a cost-effective solution compared to a full motherboard replacement or premature drive upgrade.

Why Replace the HDD Controller Board?

1. Restores consistent drive detection
2. Secures SATA and power cable routing
3. Prevents motherboard wear from direct cabling
4. Fixes random disconnections and boot errors
5.

Supports drive stability under movement
6. Aligns with drive bay housing perfectly
7. OEM interface maintains data integrity
8. Enables continued use of internal drives
This board is perfect for laptops where the hard drive fails to spin, disconnects when moved, or isn’t detected by the OS. Instead of replacing your drive or laptop, simply replace the interface board with a model-matched OEM part.

Frequently Asked Questions

Does the board include the SATA/power cable?
It typically reuses the original cable. Please inspect your cable for wear before reinstalling.
Will this fix drive not found errors?
If the drive is functional and the BIOS doesn't detect it, replacing a failed board often restores full access.

Where can I find the right model?
Check the OEM number on your original board or use our My Equipment tool for exact matching.

Do I need to format the drive after replacing the board?
No. Your drive data remains intact if the issue was the board, not the drive itself.
How do I test the new HDD board?
Power on and access BIOS. If your drive is listed, the board is functioning correctly.
What precautions should I take during install?
Always ground yourself, align the board properly, and avoid flexing or crimping the SATA cable.
