I am referencing this question from another user:

For some reason, this pesky Kingston drive I have does not want to erase on Disk Utility nor with the use of terminal commands. I have tried the method that this YouTube video explains.

This is the output from running two commands on terminal:

~ sudo diskutil eraseDisk JHFS+ noname /dev/disk2
Started erase on disk2
Unmounting disk
Creating the partition map
Error: -69877: Couldn't open device

~ diskutil  partitionDisk  /dev/disk2  1  MBR  FAT32  MYUSB  R
Started partitioning on disk2
Unmounting disk
Creating the partition map
Error: -69877: Couldn't open device
(Is a disk in use by a storage system such as AppleRAID, CoreStorage, or APFS?)

Here is the information about the disk:

/dev/disk2 (external, physical):
  #:                       TYPE NAME           SIZE       IDENTIFIER
  0:     FDisk_partition_scheme               *15.5 GB    disk2
  1:             Windows_FAT_32 1821VPC        15.5 GB    disk2s1
