Delete partition on USB drive

I have a 16GB drive earlier I used for windows bootable drive. Now I want to use it as a normal drive.

In terminal, when I used diskutil list command I get the following

/dev/disk3 (external, physical):

  #:            TYPE NAME          SIZE    IDENTIFIER

  0:   GUID_partition_scheme            *15.7 GB  disk3

  1:    Microsoft Basic Data ⁨CARDISK           15.7 GB  disk3s1


How can I remove the Microsoft Basic Data from diskutil or any other MAC tool?

Launch Disk Utility. If you are using macOS 10.13+, then you need to click "View" within Disk Utility and select "Show All Devices" so that the physical drive appears on the left pane of Disk Utility. If using macOS 10.11+, now erase the physical drive as GUID partition and MacOS Extended (Journaled) if the drive is only to be used with macOS, otherwise use exFAT file system if you need to share the drive with Windows.

To get a better picture of what you have, paste the entire output from Terminal:

diskutil list internal




If this is an external USBdrive—
