Ubuntu – Can’t mount / format USB stick

mountntfsusb

I have formatted USB stick and now I can't mount it.

Command sudo fdisk -l outputs this (shortened to only show info about sdc and sdc1):

Disk /dev/sdc: 8075 MB, 8075120640 bytes
64 heads, 32 sectors/track, 7701 cylinders, total 15771720 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x22fb6a74

   Device Boot      Start         End      Blocks   Id  System
/dev/sdc1   *           0      407551      203776   17  Hidden HPFS/NTFS

Disk /dev/sdc1: 208 MB, 208666624 bytes
64 heads, 32 sectors/track, 199 cylinders, total 407552 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x22fb6a74

     Device Boot      Start         End      Blocks   Id  System
/dev/sdc1p1   *           0      407551      203776   17  Hidden HPFS/NTFS

If I try to mount sdc1 with sudo mount -t ntfs /dev/sdc1 /mnt the output is:

NTFS signature is missing.
Failed to mount '/dev/sdc1': Invalid argument
The device '/dev/sdc1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

EDIT:

Output of command sudo lsblk -f is:

NAME   FSTYPE LABEL MOUNTPOINT
sda                 
├─sda1 ext4         /
├─sda2              
└─sda5 swap         [SWAP]

Best Answer

You formatted the USB disk wrongly: it has a Hidden HPFS/NTFS partition.

  1. Open gparted
  2. Navigate to the correct disk in the upper right corner:

  1. Go to device and choose create partition table and choose msdos
  2. Right-click the large empty square in the middle:

and choose "format to" and take FAT32

Done! ;-)
