How to block a USB pen drive from being written?

I remember I saw a Guide on this Board regarding how to prevent a USB pen drive to be written when inserted in a PC.
It dealt with Administrator and user permissions for writing on it (deleting all permissions).

May someone help me with the link?
I cannot find it

Thanks in advance

I wonders if there's anything non OS-specific.

Regarding pandlouk linked post.

Is there any reason why he writes to format the USB as NTFS?

I am asking because I'd like to do it with a stick containg "Hiren's BootCD", but the example here http://www.hiren.info/pages/bootcd-on-usb-disk says to format as FAT32.
Does it work also if I format as NTFS?

Is it because I have it formatted FAT32 that I can't see the "Security" tab?

Sorry but I am not so expert

 

Fat32 does not support access permissions (the reason why you do not see the Security Tab).

Yes, you can format it as ntfs and it will work fine.
