In the latter case, a different operating system is worth a try. In the a former case, with a bit of luck, a data recovery specialist with an appropriately equipped lab can salvage its content. If this command results in a message about an “Input/output error”, our drive is broken or otherwise fails to interact with the Linux kernel as expected. This can be verified easily with: sudo dd if=/dev/sdc of=/dev/null count=1 It still appears as a block device to the kernel and in the disk manager, but its first sector holding the partition table is not readable. Sometimes a storage medium simply refuses to work at all. almost instantaneous (unless medium is spun down or broken).only detects entirely unresponsive media.on the terminal look at the output of lsblk and ls -l /dev/disk/by-id and try to find the right device by size, partitioning, manufacturer and model name.Gnome Disks (formerly Gnome Disk Utility, a.To find the path of a storage drive in our current setup, use: Throughout this answer I'll assume, that a storage drive appears as a block device at the path /dev/sdc. ![]() fsckįsck 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. For this reason, it is strongly recommended that users not run badblocks directly, but rather use the -c option of the e2fsck and mke2fs programs. Important note: If the output of badblocks is going to be fed to the e2fsck or mke2fs programs, it is important that the block size is properly specified, since the block numbers which are generated are very dependent on the block size in use by the filesystem. Will check the whole disk and print out all bad blocks encountered on /dev/sda. Sudo fsck -t ext4 -l bad-blocks-result /dev/sda1 To just check, or to check and fix first write the result to a temporary file: sudo badblocks -sv /dev/sda > bad-blocks-result You can also use badblocks sudo badblocks -sv /dev/sda The program is bundled in the gnome-disk-utility package. Even if you don't see any bad blocks there, launch a self-test to be sure. Now if you have a query then write us in the comments below.To check for bad sectors check the SMART data, probably the best accessible by launching the Disks utility ( Palimpsest). You have successfully installed and used Testdisk for recovering files on your system. To exit from the utility you can press q.įor more usage, you can read its official documentation. Press c to copy the selected file to a different location on your system. Once the analysis is completed you will be asked to choose a partition, select one of them, and press p this will display the content of that partition. This will start and take some time to analyze disk or partition – Next, you can choose to perform a quick search or deeper search for deleted files on the disk – Next, select the partition table type on the disk and press Enter.Īnalyze the current partition structure for the lost partitions – Navigate to Proceed and then press the Enter. Press the Enter key and use the arrow key to navigate and select the disk or partition where you want to recover data. Next, run the Testdisk utility by using – tesdisk Now Testdisk has been installed on your system you can run it to recover deleted files and partitions on your system.įirst, use the following command to list all disk and partitions on your system – df -h ![]() This will display the current version of the Testdisk utility installed on your system. You can verify the installation of Testdisk by using – testdisk -v Now use the given command to install Testdisk in your system – sudo apt install testdisk -y Use the following command to update the package list – sudo apt update & sudo apt upgrade -y
