I'm running dual boot of Linux Mint 19.2 Tina and Windows 10.

I wanted to format my usb flash drive but when I open it with fdisk /dev/sdc and then type p i get shown partitions of my computer file system.

Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x73736572

Device     Boot      Start        End    Sectors   Size Id Type
/dev/sdc1       1920221984 3736432267 1816210284   866G 72 unknown

Partition table entries are not in disk order.

This is output of df command so you see the flash is mounted on /mnt/flash :

/dev/sdc         3914748    14784   3899964   1% /mnt/flash

So how do I fix it to show me partitions of my flash drive?

Your flash drive currently does not have partitions. Whatever version of fdisk you’re using is trying to interpret the start of the filesystem as a partition table (MBR).

You have two options: Continue partition-less (with mkfs.whatever /dev/sdc) or create partitions.

To create partitions, simply enter o in fdisk to create a new empty MBR partition table. You can then create partitions as usual/desired and format them.

So I had no partitions at all? Strange... Anyway I fixed it by using gParted. Formated first to clear and then I made 1 partiton as fat32. Thank you for your answer!
