linux - Trying to format a sandisk pendrive using bash

My sandisk pendrive is write protected and i have tried everything to repair it but nothing worked. Now finally i am trying to format it using bash in my windows machine. But commands like fdisk -l are not running. Can someone help?

fdisk: cannot open /proc/partitions: No such file or directory

And df or mount dont show my pendrive which is connected

root@DESKTOP-FGQQE3V:~# fdisk -l
fdisk: cannot open /proc/partitions: No such file or directory
root@DESKTOP-FGQQE3V:~# df
