The reasons that may cause the Windows 10 computer to fail to recognize the second new hard drive installed generally include the following aspects:
● Connection problem: A new hard disk may not be recognized by a Windows 10 computer if not properly connected.
● The hard disk is not initialized: if the new hard disk is not initialized, the hard disk cannot be recognized normally.
● Unpartitioned hard disk: An unpartitioned hard disk won’t appear in Windows Explorer because its space is unallocated.
● No drive letter: If the hard disk partition does not have a drive letter, it cannot be found in Windows Explorer.
● Outdated disk driver: When the driver of the new hard disk is not updated in time, your computer cannot detect and recognize the device.
The above are the main reasons why Windows 10 cannot recognize the new hard disk. After understanding, let’s learn how to solve this problem.
When your new hard disk isn’t recognized by Windows 10 , check the data and power cables . Unplug and reconnect them while the computer is off . Try connecting the data cable to a different SATA interface on the motherboard or replace the data cable to resolve the issue.
When a hard disk lacks a partition , it may not be recognized. To resolve this, initialize the disk and then create a partition . The steps are as follows:
Step 1 : Connect the hard disk to the computer, then press Windows+X and select Disk Management from the pop-up list.
Step 2 : Right-click on the hard drive that is marked “Unallocated” and select the ( Initialize Disk ) option.
Step 3: Select the partition style MBR or GPT and click OK . Choose GPT if your hard drive is 2TB or larger. Select MBR if it is less than 2TB. You may also click here for a detailed introduction to MBR and GPT .
Step 4: Once the hard disk is initialized and the status changes to Online, right-click the unallocated space, select New Simple Volume , and proceed.
Step 5 : In the New Simple Volume Wizard, set the volume size and click ( Next ).
Step 6 : Select the drive letter for the partition and click ( Next ).
Step 7: Choose NTFS as the file system, keep Allocation Unit Size at default, and set the partition name in Volume Label . Select Perform a quick format , click Next , and then Finish . Click here to learn about the NTFS file system.
Outdated drivers may prevent your Windows 10 PC from recognizing your device. To ensure smooth operation, upgrade the hard disk driver to the latest version. Here are the steps to update the driver on Windows 10.
Step 1: Start the Windows 10 computer, connect the hard disk, and press Windows + R to open the Run window. Enter devmgmt.msc and click OK to access the Device Manager.
Step 2 : In “Disk Drives”, right-click on the new hard drive and select the ( Update Driver ) option.
Step 3: Select Search automatically for updated driver software and follow the instructions to update the hard disk driver. After the update, restart the computer to check if the problem is resolved.
