![]() ![]() 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. It's a robust command with lots of useful options, and it's a great way to take control of how you manage your data.To check for bad sectors check the SMART data, probably the best accessible by launching the Disks utility ( Palimpsest). The nvme-cli command is released under a GPLv2 license. The same warnings apply here as with the format process: Back up important data first because this command erases it! $ sudo nvme sanitize /dev/nvme0nX Try nvme-cli When you get ready to sell or dispose of your NVMe computer, you probably want to erase the drive securely. Change the X to 1 or the appropriate location as listed in the results of nvme list.) Securely erasing an NVMe drive (For safety, I've replaced the actual location of the drive with X to prevent copy-paste mishaps. The subcommand is format: $ sudo nvme format /dev/nvme0nX You can format an NVMe drive with nvme-cli, but beware: This erases all of the data on the drive! If there's important data on your drive, you must back it up before doing this, or else you will lose data. This provides you with the drive's current temperature, the hours of use it's had so far, how many times it was unsafely shut down, and so on. Smart Log for NVME device:nvme0n1 namespace-id:ffffffffĮndurance group critical warning summary: 0 You can read about the overall health of a drive with the smart-log subcommand: $ sudo nvme smart-log /dev/nvme0n1 You can get even more information about the drive and the features it supports by using the id-ctrl subcommand: $ sudo nvme id-ctrl /dev/nvme0n1 It lists the serial number, brand, size, firmware revision, and so on. Node SN Model Namespace Usage Format FW Rev I used it and found an NVMe drive at /dev/nvme0n1. The sudo nvme list command lists all NVMe devices and namespaces on your machine.

For instance, on Fedora, CentOS, or similar: $ sudo dnf install nvme-cli You can install nvme-cli from your distribution's package manager. Those questions led me to an Internet search that yielded an open source project with a collection of tools to manage NVMe drives. Could I securely erase the drive? How could I check its integrity? That was interesting, but I wanted to know more about my particular NVMe drives, and I wanted to know how they compared with other drives. I learned that NVMe drives consume less power while delivering much faster access to data compared to even SSD drives over SATA. It also didn't take long for me to get curious about the technology driving this ultra-fast storage, so I did a little investigation. ![]() I love how quickly my computers boot and how quickly they're able to read and write data. My laptop has an NVMe drive, as does my desktop. Free online course: RHEL Technical Overview.
