Error while creating percistance on live usb

What have you tried:
I re-imaged usb drive using all recommended methods and following official kali guide for enabling persistence.
What is the error:
sudo mount /dev/sda3 /mnt/my_usb
mount: /mnt/my_usb: wrong fs type, bad option, bad superblock on /dev/sda3, missing codepage or helper program, or other error.
dmesg(1) may have more information after failed mount system call.

What device is this on:
2tb usb drive with kali live

Are you doing this to the drive you’re booted from? If so, you can’t do it this way. You have to edit the usb from a linux machine.

I created a new partition within the USB through Kali, but at the moment that I try to mount the partition I get the error message, again all following the official documentation from Kali Linux.

so you’re using a linux system that’s not booted from the usb?

I am loading from a USB, so let me provide some backstory, as it might help clarify the situation. I created a bootable drive with Kali Linux Live, but I encountered two major problems:

  1. File Saving and Reverted Settings: Files were not saving, and settings and updates kept reverting. This indicated that persistence was not active.
  2. Limited Partition Space: The partition containing system files was extremely small. Whenever I tried to upgrade the system, I received a memory error code.

To resolve these issues, I searched extensively online. I came across this forum where someone suggested activating persistence and provided a link from the official Kali Linux documentation on how to do this.

Following the steps outlined in the guide, I proceeded to activate persistence. However, when it came time to mount the partition, I encountered the error described in this post. Here is the link that was shared with me. Here is the link that was shared with me.

Right, like I said, you have to do this from a linux system that’s not the usb drive you’re setting up persistence on.
