Can't format pen drive, showing write protected

Question

I want to remove write protected from pen drive or just I want to format it but I'm unable to do so.

$ sudo mkfs -t vfat /dev/sdb1
mkfs.vfat 3.0.14 (23 Jan 2023)
mkfs.vfat: unable to open /dev/sdb1: Read-only file system

How can I resolve this?

Answer 1

Check whether your pen drive has a write protect switch on it, if none, the following command should help:

sudo hdparm -r0 /dev/sdb
