Restore bootable USB flash drive to normal
I found a similar post on Stack Overflow where someone had the same problem and just ran this diskutil
command from the command line:
diskutil zeroDisk /dev/disk2
Such a simple fix, so hard to find.

I’m trying to create a persistent installation of Parrot OS on my 16GB USB flash drive. I made the mistake of making the USB flash drive bootable without partitioning the drive into 2 in the beginning. Now I am unable to revert the USB flash drive back to normal.
I am using macOS. When I open Disk Utility the USB flash drive is only recognized as 701KB and I am unable to erase it using the
diskutil
in the command line since it gives the error:The chosen size is not valid for the chosen file system.
Any help is greatly appreciated, thank you.

Christopher Hostage over 5 yearsIn general, formatting a disk would get you what you wanted. The built-in Mac Disk Utility GUI is sometimes useful for it, but the usefulness of the Disk Utility has lessened in the last five years. (i.e. not showing all plugged in devices)
