Identifying Bad Sectors. A sector is the smallest physical storage unit on a disk. On most file systems it’s a fixed 512 bytes in size for HDD, 2048 for CD-ROMs, and DVD-ROMs. The latest HDDs and SSDs use 4096-byte sectors. Sectors are also referred to as blocks. Check Bad Sectors in Linux Disks Using badblocks Tool. A badblocks program enables users to scan a device for bad sectors or blocks. The device can be a hard disk or an .

Check Bad Sectors in Linux Disks Using badblocks Tool. A badblocks program enables users to scan a device for bad sectors or blocks. The device can be a hard disk or an external disk drive, represented by a file such as /dev/sdc. In this tutorial we saw how to install the smartmontools package on some of the most used Linux distributions and how to use the smartctl utility to check the status of S.M.A.R.T parameters on a storage device. We also saw what are the possible tests we can run, and what are the differences between them.
badblocks is a program to test storage devices for bad blocks. In modern HDDs and SSDs firmware automatically detects defective sectors and, where possible, takes action to correct the situation. However, firmware becomes aware of a corrupted sector only upon an attempt to use it. Badblocks may be used to test the entire device at once. My hard drive is partly visible (only 4.1 GB of 2TB) in "Disks" and has a bad sector. I have tried using the smartmontools to check for bad sectors and then used badblocks -svn /dev/sda for which I get the response. badblocks: Permission denied while trying to . Disks. To check for bad sectors check the SMART data, probably the best accessible by launching the Disks utility (Palimpsest). Even if you don't see any bad blocks there, launch a self-test to be sure. The program is bundled in the gnome-disk-utility package. Run gksudo gnome-disks.
Learn how to scan hard disk (or drive) for bad sectors or blocks with badblocks command in linux. If you'd like to do a surface scan of your drive you can use e2fsck. Use the -c option to do a bad sector scan. It should also be mentioned that nearly every Linux distro is also configured by default to periodically scan your fixed drives on boot. Use fsck to check your file system if your system fails to boot, if files on a specific disk become corrupt, or if an attached drive does not act as expected. Unmount the disks you intend to work on before attempting to check or repair them.
There are two ways to get the disk to notice bad sectors: Use smartctl -t offline /dev/sdX to tell the disk firmware to do an offline surface scan. You then just leave the disk alone (completely idle will be fastest) until it's done (check the "Offline data collection status" in smartctl .
