formatting a usb drive

Ian A. Taylor
Sir/Madam

Can somebody advise me what is going on here please

I have just opened a new usb drive that is 16gb

I place it in my computer running Ubuntu 18.04

lsb_release -a
     No LSB modules are available.
     Distributor ID:    Ubuntu
     Description:    Ubuntu 18.04.2 LTS
     Release:    18.04
     Codename:    bionic

uname -a
    Linux lupus-st-andrews-ac-uk 4.15.0-45-generic #48-Ubuntu SMP Tue
Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Run parted

parted /dev/sdc
     GNU Parted 3.2
     Using /dev/sdc
     Welcome to GNU Parted! Type 'help' to view a list of commands.
     (parted) p
     Error: /dev/sdc: unrecognised disk label
     Model: (file)
     Disk /dev/sdc: 3093MB
     Sector size (logical/physical): 512B/512B
     Partition Table: unknown
     Disk Flags:

Why does it only see 3093Mb (a quarter of the drive size)

What am I missing here ?

Thanking you

Yours in confusion

I believe so

mount | grep sdc
/dev/sdc1 on /media/lupusiat/9E2B-3CB5 type vfat
(rw,nosuid,nodev,relatime,uid=1001,gid=1001,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro,uhelper=udisks2)

Various possible reasons, such as multiple partitions, an NTFS volume,
an encrypted volume, an incorrect partition table.

Install GParted, and being very careful that you do NOT reformat your
hard disk instead, remove any existing partitions on the USB drive,
make a new MBR partition table and a new FAT32 partition. That should
work.
