Mounting Drives on Linux

In this post, we will look at different mounting options.

Mounting external drives in read-write mode

source: http://www.cyberciti.biz/datacenter/linux-unix-bsd-osx-cannot-write-to-hard-disk/

mount -o remount,rw /media/"disk_name" 

Replace disk_name with the drive name

List the disk formatted in NTFS

fdisk -l | grep NTFS

Mount the drive formatted in NTFS

sudo mount -t ntfs-3g /dev/NTFS_PARTITION /mount/DIRECTORY

Where, NTFS_PARTITION is the partition of the drive you want to mount not the device and DIRECTORY is the the location where you want to mount

Rename USB drive in Ubuntu (source)

Firstly unmount the device

sudo unmount /dev/sdb1

sudo ntfslabel /dev/sdb1 my_external

Now remove the device and put back again and mount it

Unmount a busy drive

sudo umount -l /PATH/OF/BUSY-DEVICE

List block devices

lsblk

With some additional parameters

sudo lsblk --output NAME,FSTYPE,LABEL,UUID,MODE

Mounting LUKS encrypted disks

Install crytsetup

sudo apt-get install cryptsetup

Find the full path of your device (e.g. /dev/sda)

sudo fdisk -l

Unlock encrypted disk and create a mapper

sudo cryptsetup luksOpen /dev/sda first_disk

You can check the status of the above mapper using the following command

sudo cryptsetup -v first_disk

Mount the mapper

sudo mount /dev/mapper/first_disk /mount/mount_directory

Unmounting and lock LUKS encrypted partition

Unmount the disk

sudo umount /mount/mount_directory

Lock the partition using cryptsetup

sudo cryptsetup luksClose /dev/mapper/first_disk
