How can I copy, or just access a file on the USB drive from Ubuntu Server? This answer here does not work, I am getting

mount: you must specify the filesystem type

which no one explained how to solve. This happens after I type

sudo mount /dev/sdc /media/usb

where /dev/sdc is supposedly my USB.

How can I do it?

    What file system is on your USB drive?

  • because I also have a windows PC, on which I made that USB.. Jun 5, 2015 at 20:18
  • First thing you need to do is to show what command line you used to generate that error. Otherwise, nobody can tell you what you might be doing wrong. It may be a simple syntax error. Jun 5, 2015 at 20:40

You specify the filesystem type with the -t option. As described in man mount:

   -t, --types fstype
          The argument following the -t is used to indicate the filesystem
          type.  The filesystem types which are currently supported depend
          on the running  kernel.   See  /proc/filesystems  and  /lib/mod‐
          ules/$(uname  -r)/kernel/fs  for a complete list of the filesys‐
          tems.  The most common are ext2, ext3, ext4, xfs,  btrfs,  vfat,
          sysfs, proc, nfs and cifs.

So, to mount a FAT32 (vfat) drive, you would run:

sudo mount -t vfat /dev/sdc /media/usb

However, you don't mount devices, you mount partitions. What you're after is probably:

 sudo mount /dev/sdc1 /media/usb

Or, if it still complains:

sudo mount -t vfat /dev/sdc1 /media/usb

For more details, update your question with the output of sudo fdisk -l /dev/sdc.


Launch the app gnome-disk-utility, find your usb on the sidebar, and click the triangle play button under the filesystem graph and it should mount it.

Like this: mountusb:
