Normally the disk space is printed in units of 1024 bytes, but this can be overridden. With no arguments, ‘du’ reports the disk space for the current directory. ‘du’ reports the amount of disk space used by the set of specified files and for each subdirectory (of directory arguments). Using the df command with -a or –all it shows dummy file systems information along with all the basic file system disk usage info:ĭf -a Linux Command To Check Hard Disk Size in GBĪs the disk space is shown in 1K blocks by default, users can use “-h” command parameter to show the file system disk space usage data in “human readable” format.ĭf -h Command to Display the Total Disk Usage of the Current Directory

It shows the device name, total blocks, total disk space, used disk space, free disk space and mount points. When executed the df command displays the information about the file system disk space usage. They also provide quick (historical stats only) so you can use without any scans. If an argument is the absolute file name of a disk device node containing a mounted file system, df shows the space available on that file system rather than on the file system containing the device node (which is always the root file system). 1 I'd use the smartctl or gnome-disks tools you have already mentioned they read the health of the drive from the circuitry of the drive itself, and not file-system, thus do not care if the drive contains ntfs, ext, btrfs, xfs or any other file system. Always unmount a partition first before you can run fsck on it. Warning: Try out fsck commands on test Linux servers only, unless you know what you’re doing. Execute sensors command to find out CPU temperature in Ubuntu Linux. Run hddtemp command to see SSD and hard drive temperature in Ubuntu.
#Hard disk health check ubuntu install
It is a front-end for several filesystem checkers. Install the lm-sensors and hddtemp (NOT available in Ubuntu v22.04+) packages in Ubuntu using the following command: sudo apt install hddtemp lm-sensors. Disk space is shown in 1K blocks by default, unless the environment variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used. fsck Filesystem Consistency Check fsck is a system utility used to check and optionally repair a Linux filesystem. If no file name is given, the space available on all currently mounted file systems is shown.
The df command displays the amount of disk space available on the file system. The “df” command is for “disk filesystem” and is a great tool to know about the disk space usage on Linux Systems. du command – ‘du’ reports the amount of disk space used by the set of specified files and for each subdirectory (of directory arguments).Disk space is shown in 1K blocks by default. df command – Shows the amount of disk space used and available on Linux file systems.
#Hard disk health check ubuntu how to
In this tutorial, we will see how to check the health of our disks in Linux. But hard drive failures are a well-documented issue. That’s why many users do not even consider the possibility of losing data due to hardware damage. It also indicates when tests have been performed and what the results of those tests were.įor more options about smartctl, please check here or here. Overview All of us today have great expectations of data-storage reliability. This shows various SMART status information, such as the drive temperature, how many hours it has been powered on, and so forth. The -a option shows the specifics of the SMART attributes and test history. SMART support is: Available - device has SMART capability. Model Family: Seagate Barracuda 7200.10 familyĭevice is: In smartctl database ĪTA Standard is: Exact ATA specification draft version not indicated In a system with a lot of drives, having this information recorded can assist in knowing which drive device (i.e., /dev/sda) corresponds with which physical drive.
#Hard disk health check ubuntu serial
With the -i option, you can view the type of drive, its serial number, and so forth. Obtaining information on the drive is useful as well. SMART overall-health self-assessment test result: PASSED Smartctl version 5.38 Copyright (C) 2002-8 Bruce Allen You can quickly check the overall health of a drive by using: # smartctl -H /dev/sda Compare the features of the different Hard Disk Sentinel versions in the store to decide which is better for you.
#Hard disk health check ubuntu download
The smartctl program also allows for you to view and test SMART attributes of a drive. Download add-ons, extensions for Hard Disk Sentinel Check out our HDD Monitoring Blog. On a Red Hat Enterprise Linux system, use: # chkconfig smartd on When smartd is configured, make sure to enable the monitoring daemon if it is not already started.
