When you are finished with the device, don't forget to unmount the drive before disconnecting it. See MountingWindowsPartitions for more information. Note: You must have the ntfs-3g driver installed. Sudo mount -t ntfs-3g /dev/sdb1 /media/external Otherwise, if the device is formatted with NTFS, run: If you don't use those extra options you may not be able to read and write the drive with your regular username. Sudo mount -t vfat /dev/sdb1 /media/external -o uid=1000,gid=1000,utf8,dmask=027,fmask=137The options following the "-o" give you ownership of the drive, and the masks allow for extra security for file system permissions. Let's say the device is /dev/sdb1, the filesystem is FAT16 or FAT32 (like it is for most USB flash drives), and we want to mount it at /media/external (having already created the mount point): Instead, use an underscore to separate words (like "my_external"). You can call it whatever you want, but if you use spaces in the name it gets a little more complicated. Now we need to create a mount point for the device. For more information about filesystems, see LinuxFilesystemsExplained. Sudo fdisk -lFind your device in the list. Most flash drives are FAT16 or FAT32 and most external hard disks are NTFS. First, you must know what device you are dealing with and what filesystem it is formatted with. Once a filesystem is mentioned in /etc/fstab, we can mount it by just giving the mount point or the device.Sometimes, devices don't automount, in which case you should try to manually mount them. Thus, if we add the following line in this file, the archLinux.iso image will be automatically mounted on /mnt/archIso after system boot: /media/Data/archLinux.iso /mnt/archIso udf ro,relatime,utf8 0 0 dev/sda2 /media/Data ntfs-3g defaults,locale=en_US.UTF-8ĐĐ dev/sda3 /media/Backup ntfs-3g defaults,locale=en_US.UTF-8ĐĐ dev/sdb2 /home ext4 rw,defaults,noatime,data=orderedĐĒ dev/sdb1 / ext4 rw,defaults,noatime,commit=120,data=orderedĐđ Let’s see an /etc/fstab example: $ cat /etc/fstab The /etc/fstab file contains lines describing which filesystems or devices are to be mounted on which mount points, and with which mount options.Īll filesystems listed in the fstab file will be mounted automatically during system boot, except for the lines containing the “ noauto” mount option. The /etc/fstab file can help us to achieve this. In addition to searching in /dev/disk/by-label, we can also identify the block device file of our USB device by using the fdisk command with the -l option:įor some filesystems, we may want to have them automatically mounted after system boot or reboot. CirrOS, for instance, doesn’t populate the by-label directory by default. However, not all Linux distributions will populate the /dev/disk/by-label directory. The ls -l output shows the block device file of our USB stick is /dev/sdd1. Lrwxrwxrwx 1 root root 10 Nov 1 18:07 SanDisk_16G ->. Lrwxrwxrwx 1 root root 10 Oct 28 23:47 Backup ->. Say we plug in a 16GB USB stick that has a single partition, which is formatted in ext4 format with label “ SanDisk_16G“: $ pwd Let’s see an example of how to find the device we’re about to mount. To identify the partition on the USB drive, we can go to /dev/disk/by-label to find the block device by checking the label of the partition. Most modern Linux distributions will populate a /dev/disk/by-label directory by udev rules. To mount a USB drive in Linux, first of all, we have to find out the name of the USB device we want to mount.Īfter we plug in a USB device, the Linux system adds a new block device file into the /dev directory. ![]() media/Data/archLinux.iso on /mnt/archIso type udf (ro,relatime,utf8) 3. Let’s see how to get the mounting information only for udf (Universal Disk Format) filesystems: $ mount -t udf However, if we want to check the mounting information of a particular filesystem type, we can make use of the -t type option. The command mount will, by default, report all mounted filesystems, including the virtual ones such as cgroup on /sys/fs. We’ll cover some commonly used mount options in the following sections. ![]() This is the directory the device is mounted to - the root directory in this case. In this case, it’s the first partition on the second hard disk. The device or filesystem name we want to mount.Let’s pick the last output line as an example to understand the information that the mount command gives us: /dev/sdb1 on / type ext4 (rw,noatime,commit=120) dev/sdb1 on / type ext4 (rw,noatime,commit=120) media/Data/archLinux.iso on /mnt/archIso type udf (ro,relatime,utf8) Run on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)Ĭgroup on /sys/fs/cgroup/rdma type cgroup (rw,nosuid,nodev,noexec,relatime,rdma) Sys on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)ĭev on /dev type devtmpfs (rw,nosuid,relatime,size=8133056k,nr_inodes=2033264,mode=755) Proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
