My booted drive has gone read only mode. no operations can be done on my drive
So i was installing linux (pop_os) on my laptop. i successfully installed it on my laptop with my 8gb booted pendrive. but when i tried to format the booted pendrive after the full installation of pop os. the pendrive doesn't show up in file app or in other locations. So i opened disk(disk management tool built in pop os) and there it doesn't show option to format or to do anything to the booted pendrive as shown in below pictures. 
So i opened gparted in my terminal and also there it doesn't show option to format except new option whenever i click new option in terminal it says (read only file systems). as shown in below pictures
So i tried the df command in terminal and the pendrive wasn't mentioned there. as shown in below pictures
So i thought it was not mounted . so i tried to mount it. but this error comes mount: /media/usb3: wrong fs type, bad option,bad superblock on /dev/sdb, missing codepage or helper program, or other error. as shown in below pictures
No physical button was pressed on my pendrive that invoke read only mode
can anybody help me?
