This is down right annoying, the write protect slider on my sandisk SD card fell out for the second time. Lucky this time it fell on the seat I was sitting on. The first time it happened it fell into the carpet, that took for ever to find. I'm buying some super glue and gluing all of them. I already have one SD card that has a missing slider. They need to eliminate that problem and quit making SD card like that.

 

Until the day you accidentally format one of your SD's or overwrite them and blame it for not having the Write protect enabled.

In all seriousness, stop buying shit SD cards and ditch broken ones.
Their cheap as fuck anyway.

Also, they do make SD's without wirte protect switches.
Their called Mini and Micro SD's.

 

I had this problem also, same sandisk brand. I ended up modifying one of those Sd-to-Usb adapters to override the write protection. little annoying but its only one card

 

That's a good idea too and I have one of those usb card reads, but sometimes the SD card needs to be written to while it's in the Wii SD card slot. I wonder if the Wii will write to a SD card with the slider missing?
