![]() If you do such a thing, there is a high probability that it can damage the system. ![]() However, this fsck command is unusable on a mounted partition. This command will check the sda1 partition only. ![]() All you have to do is open a terminal and write: Fsck is an abbreviation for the 'File System Consistency check’. In the Linux operating system, a powerful command exists, known as 'fsck’. Other than that, the 'y'option can be used in place of 'a’.įor performing the error check on just one partition, you can run the command from your terminal: To check the error and repair it at the same time, use 'a'option. It performs a similar function as 'chkdsk'in the Windows operating system.įor checking the Linux filesystem for errors, the fsck command comes in handy more than often. The 'fsck'is quite handy in the Linux system as it is used for checking errors in the filesystem. This command finds out simple I/O performance. Step 3: The dd command is also used to check the server latency dd if=/dev/zero of=/tmp/test2.img bs=512 count=1000 oflag=dsync Step 2: In order to measure the server throughput (writing speed) dd if=/dev/zero of=/tmp/test1.img bs=1G count=1 oflag=dsync You can also login to a remote server if need be. Let us see how the 'dd'command is used to check the I/O performance. The 'dd'command in Linux is used to check the reading and writing performance of the disk on the Linux platform. This is why they are mentioned for your familiarity. ''sudo dnf install smartmontools’’ OpenSUSEĪs we can see, all of the different Linux distribution systems will display different commands. ''Sudo apt-get install smartmontools’’ For Arch Linux ''Sudo apt install smartmontools’’ For Debian Before looking at how to use this tool, let us first examine how the health of the hard drive is checked with smartctl.įor installing the Smartmontools, you need to open the terminal and follow the given instructions that show on your particular Linux distribution (there are so many). But the quickest of the lot is probably smartctl. In the case of Linux, there are multiple ways to affirm the S.M.A.R.T status of your hard drive. You may also check the box it came packaged in. A fast way to check if your hard drive is equipped with the SMART feature is to extract it from your personal computer and check the information given on the label. It is a useful tool, which allows the OS (Linux and Windows) to check up on their health and overall functionality. The modern Linux hard drives come with the S.M.A.R.T function. Follow these simple, quick commands and you can execute a range of functions with it. It can also perform a range of functions that will be examined below. To your benefit, Live CD of any given Linux Distros can easily detect the drive corruption and allow the users to recover their much-needed data in its original form.įsck function is not just used for checking the hard drive in Linux systems. It often occurs when the situation has gone from bad to worse. Bad sectors present on the hard drive: Bad blocks on the hard drive could cause drive corruption. It could also be due to access to unknown internet connections.ģ. It is often due to accessing of compromised websites from where these elements enter the system. ![]() Infection due to viruses: Malicious software or virus infection could be another cause for the corruption of the drive. This is often due to a lack of understanding or toying with files that you may be unaware of in the system.Ģ. Accidental data deletion or some human error: Due to accidental deletion of key data, the Linux drive is often corrupted. The Linux drive often gets corrupted to these common causes:ġ. The particular behavior of fsck can differ, but it generally follows a specific protocol for internal operations and give the users a common command-line interface. It works on the data structures directly, which are stored on the disk. For the most part, fsck is activated by the system administrator manually or is automatically used at boot time. The Linux check disk (fsck) is a standard operation in Unix-based operating systems, the likes of which includes Linux and Apple operating systems. In certain systems, fsck often runs by default, usually, after the system shuts down improperly or after a series of reboots. Using a set of built-in tools, it checks the disk and then auto-generates a report of its evaluation. Simply put, it is a utility that helps a user scan the file database for any existing errors and repairs them if need be. In Linux, the check disk command is represented by fsck, which is an abbreviation for file system consistency check. The Linux check disk option checks bad sectors and errors on the drive.
