You can view the full user manual for backblocks by running: man badblocks Viewing SMART Status in a GUI Using gsmartcontrol However, once completed, you will receive a report on how many bad blocks or sector was found – which can be a good indicator of whether your disk has been damaged. Running badblocks may take quite a while, depending on the size of the disk. Finally, /dev/sda is the path to the device to be checked. sudo badblocks -v /dev/sdaĪbove, the -v option is used, which tells badblocks to be verbose and output as much information as possible while it is running. When it’s done, you’ll get a full report on how many bad blocks were found. badblocks will scan your disk block by block if a block is damaged, it is marked as bad -, and the system actively avoids storing data on that part of the hard disk. It will check for bad blocks on your disk.Ī block (or sector) is an area of the physical storage device where data is stored.

To check the health of a disk in the Linux operating system, we use a program called SmartCTL. You can install it on Ubuntu and Debian based systems by running: sudo apt install smartmontools The smartmontools contains the smartctl package, which can query the SMART status of a physical hard drive. This information can be queried to find out whether a drive is reporting any issues. S.M.A.R.T.
