Windows 10 can support multiple hard disks. Some systems may support the internal SSD and the internal hard disk, depending on the motherboard. You can also connect multiple external hard disks (or SSDs) to your computer.

Configuring an external hard drive is not difficult. It is plugged into one USB port, can work with a USB 2.0 or USB 3.0 port, and is plug & play. Windows 10 can automatically detect it and install the correct drivers.

To access the hard disk, open Windows Explorer and it will appear in this section of the computer. You can copy and paste files there as easily as on an internal drive.

Hard disk

The second hard disk was not detected in Windows 10

A hard disk that is connected internally or externally is automatically detected. You should hear the sound of the new detected hardware when you connect it to the device, and wait a few seconds when you install the driver for this drive, but the device will be available almost immediately.

If Windows 10 did not detect your other hard drive, try the solutions below.

Replace the USB port and cable

  • One of the main reasons why a hard drive goes unnoticed is often the cable that connects it to your computer. Replace it and check if the disc is recognized.
  • In the same way, try connecting the drive to another USB port. A loose port can be the reason why a device or hard drive is not connected properly.
  • Connect the hard drive directly to the computer. Do not use a USB hub or extension cord. If you have another computer, try connecting a hard drive to it and see if it is detected.

Check for hardware changes

Windows 10 may not have detected the drive as new hardware. If it does not recognize it as new hardware, it cannot connect it.

  • Open Device management (Windows + X> Device Manager).
  • Click the button Check for hardware changes at the top of the window.
  • Windows 10 recognizes the hard drive and should show upFile management below This PC.

Install your own applications / drivers

Some hard drives come with drivers or applications. The absence of these may prevent the disc from being recognized.

  • Check with your hard disk manufacturer for drivers or applications.
  • Reconnect the drive and check if it is visibleFile management.

Updating drivers

Windows 10 may have outdated drivers on your hard disk. Updating them can allow the drive to connect to the system.

  • Open Device management (Windows + X> Device Manager).
  • Expand the branch Disk drives.
  • Right-click the secondary drive and select Update the driver.
  • Find the drivers online and install the available ones.
  • Restart the computer.

Change the drive letter

When you connect a hard drive to your system, Windows 10 automatically assigns it the drive letter needed to enter the drive’s “address.” The drive letter plays an important role in making the drive itself available. If your secondary hard drive is not recognized, try changing the drive letter.

  • Press the hot key Windows + R to open a dialogue Run.
  • Come in diskmgmt.msc and press Entrance.
  • In Disk Management, right-click the drive and select an option Change the drive letter and paths.
  • Select a new letter for the station.
  • Click To follow and a new letter is assigned to the station.
  • Access to the stationFile management.

The secondary drive, unless it is physically damaged or the data is corrupted, is normally detected without too much trouble. If you suspect that the drive is physically damaged, you should consider data recovery options. You may no longer be able to use the disc to store files. If the data is corrupted, the drive may still be usable because data corruption does not indicate hardware damage.
