How to remove write protected system on USB?

I have deleted a USB disk using GParted. I am trying to create a new disk using the unallocated space, and I found this message.

Can't write to /dev/sdb, because it is opened read-only.

Run the following commands:

sudo hdparm -r0 /dev/sdb

sudo umount /dev/sdb

Then go to Gparted and format the drive as FAT32.

Now it can be opened by Windows or any other operating system.
