Over the years, I have had several cases where either an SD card, a USB stick or any other removable storage medium has had a physical defect, and after some use, or a certain amount of formatting, it becomes a Read only drive no matter what OS or means of formatting it you use, including the dd utility. In most of these cases, everything I have read says that this is almost 100% of the time a hardware failure and/or a defective storage medium, which I would agree with.
In my case, I am not trying to fix a damaged USB, or SD card, but instead, trying to write files to it, and then physically modify it (and do "targeted damage"), so that after I have the files on it that I want, it is impossible for any software whatsoever to modify it, and it is impossible to put it back into RW mode again.
Does anyone know of any way to permanently alter, or intentionally damage, an SD card or USB stick, so that It will forever be stuck in read only mode? I can't find any sort of starting point anywhere on the internet, so even links, blogs, or articles involving this subject matter would be helpful.
If you have the expertise to provide direct instructions for a task such as this, a writeup would be even better!
