As far I know, my drive is mounted under /dev directory as /dev/sda and the partitions are mounted as /dev/sda1 or /dev/sda2 but I have to go to /media/DATA to access my data on a partition. This page says that /dev/sda is called a drive and /dev/sdb1 is called a partition. I want to ask what /media/DATA is called and how do I find(using command-line of course) /media/DATA if I know of /dev/sdb1 or vice-versa.

  • /media/DATA is a mounted file system that exists on a partition /dev/sda1 that exists on a drive /dev/sda. – jc__ Aug 19 '16 at 18:31

/media/DATA is your mounted file system.

/dev/sda1 is the partition.

/dev/sda is the drive.

If you wanted to interact with the file system, say create a file, you would interact with /media/DATA.

If you wanted to interact with the partition, say format or create a file system you would interact with /dev/sda1.

If you wanted to interact with the drive itself, say backup your partition table dd if=/dev/sda of=/media/DATA/partition_table.img bs=512 count=1 you would interact with /dev/sda.

  • Use the mount command. It will list the mount point to the partition. Depending on your version you may need the list switch. mount -l. – jc__ Aug 19 '16 at 18:56
  • Just one last question: Is it possible to backup a partition same way as you took a backup for the drive? – 7_R3X Aug 19 '16 at 19:00
  • Not sure what exactly you are asking. If you want to create a backup of a partition, say your OS, you could use tools like clonezilla or even dd. – jc__ Aug 19 '16 at 19:03
  • What I want to ask is whether it is possible to use dd to create backup of a partition as in dd if=/dev/sda1 of=/media/somewhere/abc.img? – 7_R3X Aug 19 '16 at 19:05
