Reasons and solutions to Acer laptop hard drive not detected
There are six main reasons why Acer laptop hard drive not detected. I will walk you through them one by one and find the corresponding solutions.
1. The drive is not enabled in the BIOS
If your internal hard disk is not detected, maybe it is turned off in System Setup. System Setup is also called the System BIOS or sometimes CMOS Setup.

When you find laptop disk is not detected in BIOS, you should inspect the hard drive connections and the motherboard. Do not be cheated by seemingly normal cable from the exterior, any folding, creasing, crimping data cable can cause the wires to break inside the insulation.
The BIOS will not detect a hard disk if the data cable is damaged or the connection is incorrect. Serial ATA cables, in particular, can sometimes fall out of their connection.
