does not work for me on an m1 mac,

mount_msdos: /dev/disk4: Operation not permitted
mount: /Volumes/nrf failed with 71

@mohamed-ea @BrianHenryIE seems like this is a common issue now, I solved it on my case. I was getting:

$ sudo mount -w -t msdos /dev/disk6 /Volumes/fat
mount_msdos: Unsupported sector size (0)
mount: /Volumes/fat failed with 71

The problem is because we were trying to either mount the disk or the wrong partition, make sure you are mounting the correct partition on your disk

it's work for me, thanks. I find the correct partition on my disk. it's disk4s1 instead of disk4 on my Macbook M3.
