  2. Step 2: In the resize window, click on the 'Advanced' button at the bottom of the window. This will allow you to specify a different block size.
  3. Step 3: Select the physical block size as 2048 bytes (or the correct value for your device) and then click 'OK'. This will resize the partition to match the physical block size.

Updating the GParted driver descriptor

  1. Step 1: Open a terminal window and type 'sudo apt-get update' to update the package list.
  2. Step 2: Then, type 'sudo apt-get install gparted-firmware' to update the GParted drivers. This command will download and install the latest firmware for GParted.
