How to clear persistent storage on live Linux USB

now I want to share my experience about linux usb persistent live modeI searching in google on how to clear data persistent and I found it and I will share here,
 this the quote 
"Yes it is possible.
If you're booting from the USB, you don't want to repartition the whole thing, you just want to recreate the loopback casper-rw partition.
I've just done it with a Karmic Koala USB stick from 2009. Current ones may work a bit differently (I've been on a bit of a holiday from Ubuntu the last year or so).
Enable expert mode and remove "persistent" from the kernel boot command line. Then it won't even try to use the casper-rw file for persistence (it will use a ramdisk overlay instead).
Say your usb stick is mounted at /cdrom (for some reason that's what I got).
You will need to do
sudo mkfs.ext3 /cdrom/casper-rw
and prompt it to proceed even though the file is not a block device.
If it complains that your USB stick is mounted read-only, use
sudo mount -o remount -o rw /cdrom
first, to make it read-write.
You can also do the mkfs command line on any other working linux system where you can mount your USB stick."


here I use linux mint
