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. You can also use badblocks sudo badblocks -sv /dev/sda will check the whole disk and print out all bad blocks encountered on /dev/sda. fsck itself will not help you find bad sectors, worse still, if there are a lot of bad sectors it can damage your data even more. Use it only when the disk is healthy. share|improve this answer edited Jun 1 '15 at 22:20 Dave Jarvis 5011417 answered Aug 29 '11 at 6:53 arrange 9,1462525 1 Thanks a lot, that gave me the bad sector info I was looking for. –Guillaume Coté Aug 30 '11 at 1:04 1 Actually badblocks's manual discourages from using it directly and directs users to e2fsck with "-c" (for read only check) or "-cc" (for read write check) option. –mrówa Apr

Disk Error Checking Taking Forever
before everybody else. RSS ALL ARTICLES FEATURES ONLY TRIVIA Search How-To Geek The Beginner's disk error checking software Guide to Linux Disk Utilities Knowing how to check the condition of your hard disk is useful to determine when to replace disk error checking log your hard disk. In today's article, we will show you some Linux disk utilities to diagnose the health of your hard disk. Image by Scoobay S.M.A.R.T System Most modern ATA and SCSI hard disks have a Self-Monitoring, http://askubuntu.com/questions/59064/how-to-run-a-checkdisk Analysis, and Reporting Technology (SMART) system. SMART hard disks internally monitor their own health and performance. The SMART tool assesses the condition of your hard disk based on: the throughput of the hard disk, the seek errors rate of the magnetic heads, and other attributes that your hard disk manufacturer built into their hard disk. Most implementations of SMART systems allow users to perform self-tests to monitor the performance and reliability of their hard disks. http://www.howtogeek.com/howto/37659/the-beginners-guide-to-linux-disk-utilities/ The simplest way to perform a SMART system test with Ubuntu is using the ‘Disk Utility' under the ‘System' > ‘Administration' menu. The disk utility lets you see the model, serial number, firmware, and the overall health assessment of the hard disk, as well as whether a SMART system is enabled on the hard disk. The ‘SMART data' button lets you see the SMART features of your hard disk. The ‘Run Self-test' button lets you initiate a short,extended, or a conveyance self-test on the hard disk. When you execute these tests, you'll see a progress meter, letting you see how far through the test is and what the estimated time of completion is. The ‘Attributed section' lets you see the errors and self-test information. File System Check There some other tools, beside the Disk Utility GUI, that we can use to diagnose the health of our hard disk. The File System Check (FSCK), that only comes as a command line tool, is one of the tools that we often use to check the condition of our hard disk. You can use the ‘Check Filesystem' feature of the ‘Disk Utility' to perform the same check,if you are not a command line geek like us. Of course, there are some situations where we have to use the command line tool to check our file

(Photo credit: Wikipedia) If your system regularly does ubuntu check disk or scan disks on boot up and if it often finds errors during the disk error check, its highly possible that you have bad sectors on your hard disk. In such cases its highly recommended to do a disk check to detect if you have bad sectors on the disk. What is a bad sector? A bad sector is a sector on a computer's disk drive or flash memory that cannot be used due to permanent damage (or an OS inability to successfully access it), such as disk error checking physical damage to the disk surface (or sometimes sectors being stuck in a magnetic or digital state that cannot be reversed) or failed flash memory transistors. The simplest way to do a check on a disk (ubuntu check disk) is to use the badblocks command from the command line in Linux. Here is how to check a disk partition(in this case /dev/sdc1) for errors: sudo badblocks -v /dev/sdc1 The output will be in the following format: tech@hacks:~$ sudo badblocks -v /dev/sdc1 Checking blocks 0 to 130954239 Checking for bad blocks (read-only test): 5621828 done, 3:37 elapsed 5621860 done, 8:43 elapsed 5621861 done, 13:25 elapsed 5621862 done, 17:57 elapsed done Pass completed, 4 bad blocks found. If you find bad sectors it usually means its time to change your disk. The situation will most probably get worse over time, but there is a tiny possibility that these are false positives(mostly coz of problems elsewhere in the system). The alternative option is to mark these blocks as badblocks and tell your system to not write any data there. This will surely buy you some more life of the disk. Note: The second option is cheaper(takes a bit of time though) and effective way of finding over time if your disk really
