How to fix an SD card with a broken read-only lock
I bought this SD card from a Chinese eBayer for half the retail price. It took about a week for the plastic read-only lock to break off. Damn thing just fell out. Last time I EVER buy a media card with a read-only lock (its optional per SD card specifications). This, as you may know, renders the card unwriteable since a media card reader thinks that the card is write-protected if the notch isn’t filled. Now, how do I convince the card reader the notch is filled? I give it a little band-aid.
The supplies:
- SD card with a broken read-only lock
- Cutting plier or wire cutter
- Medium size paper clip
- Krazyglue
All the medium size paper clips around the office that day were the same exact height as the plastic lock that broke off, lucky me. I cut it to length using a cutting plier for a clean edge and put a dab (a DAB!!) of superglue on there. I let it dry and gave it a test run. Yay, it works. Permanently set to read/write and works flawlessly.

You didn’t need to go through all of that trouble. A layer or two of scotch tape could have fixed the problem right away.

Nice! I needed this a while back - I tried scotch tape, by the way, but it would just come off and was unreliable - this is perfect.
