Fix Linux Hard Drive Not Detected

If the newly added hard drive is not showing up in the Linux system, it may be due to the following reasons:

1. The hard drive is not properly connected: make sure the hard drive is securely connected to the motherboard and power supply, and all connection cables are firmly attached.
2. If the hard drive is not recognized: run the following command in the terminal to check if the new hard drive is recognized by the system:

sudo fdisk -l

If the hard drive is not listed, it may be necessary to restart the system or reconnect the hard drive.

1. The hard drive is not mounted: If the hard drive is recognized but not showing up in the file system, it may be because the hard drive is not correctly mounted. Run the following command in the terminal to mount the hard drive:

sudo mount /dev/sdX /mnt

/dev/sdX is the device name for the hard drive, and /mnt is the mounting point.

1. File system error: If the hard drive has been properly mounted but still cannot display, it may be due to a file system error. You can use the following command to repair the file system:

sudo fsck /dev/sdX

Please note that the “/dev/sdX” in the above command should be replaced with the actual device name of the hard drive.

If the above methods still cannot solve the problem, it may be necessary to further check for hardware malfunctions in the hard drive or try connecting and testing the hard drive in another system.
