Card reader that will ignore lock on SD card

Is there an SD card reader I can buy that ignores the locked position or firmware/driver that can ignore it? I have a bunch of SD cards already so I would like to use them, I forget to move the switch but worst case scenario I will use MicroSD and just use that so the lock isn't a problem. I did not see any forum posts on this, I searched before I made this topic.

IMHO it's better to modify the card reader electrically or mechanically. Just choose the model of the card reader, which is easier to disassemble and then assemble again. :)
I did it at an early stage of CHDK porting...

Is there a tutorial? I could not find one, I saw these topics but it isn't certain to me. https://superuser.com/questions/666588/bypass-read-only-sd-card-with-missing-lock-slider

Almost all cheap card readers ignore card locks.
I sent you a link to the PM, where you can find a cheap reader like the one I use.

Look there

Hmm. All my cheap card readers(full-sized, not micro SD) that I bought in the 2000s did not ignore WP locks. Maybe now everything has changed?

If you buy something like this, you will certainly not go wrong.
There are several reasons for this, first of all it is a cheap product and any additional sensor would raise the price, the second reason is that there is no place to install the sensor, only the contacts enter the slot.

Thank you so much everyone! I will get a cheap reader, this is great!

I don't know if its on the wiki, I think it should be added if its not already there, should I make a new page or link to these forum post? I have just edited the downloads section because I did not know STICK or CHIMP existed, I think it will be helpful for new users. https://chdk.fandom.com/wiki/Downloads

Please feel free to make a new page and link it in somewhere useful.

Well, STICK and CHIMP figure prominently in the Prepare Your SD Card page and elsewhere.  But adding to the Downloads page (for people who skip straight there) cerrtainly won't hurt.

Edit : now that I go back and look, it's interesting that CHIMP never made it to the CHDK User Manual and STICK only gets one obscure reference.  Still it has been more than a few years (2015) since the last major updates to that manual.
