Causes and solutions to Acer laptop hard drive not detected

There are 3 main reasons why Acer laptop hard drives not recognized or detected. Next, I will walk you through them one by one and offer the corresponding solutions.

1. The drive is not enabled in the BIOS

If your Acer laptop internal hard disk is not detected, maybe it has been turned off in System Setup. It is also known as the System BIOS or sometimes CMOS Setup. Therefore, you should enable it in System Setup. Some motherboard manufacturers disable the unused ports in the BIOS by default. You need to enter the System BIOS to verify their current state. Different manufacturers have methods to enter System BIOS. For example, you can press F2 to enter the System BIOS for Acer and Dell computer.

Enable Flash Drive Bios

Besides, you can try to change the disk controller setting from AHCI to IDE in BIOS Setup. It is a method that worth trying according to the feedback of some computer users who have the similar issue.

2. Faulty or unplugged data cable

When you find Acer laptop hard 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 the Acer laptop 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. Be sure to check your SATA cables are tightly connected to the SATA port connection. The easiest way to test a cable is to replace it with another cable.

3. Out-dated or damaged driver

If your driver is out-dated or damaged, the Acer hard drive will not be detected. Therefore you should go to the Device Manager and check the driver. To update driver or reinstall the driver, you can follow the steps below.

3.1. To update driver

Access Device Manager by typing device manager in the Search Box and hit Enter. Expand the categories of Disk drivers. Find the name of your hard drive, right-click it and select Update Driver Software…. Then select Search automatically for updated driver software.
