On a whim, I removed the micro memory card from one adapter, and put it in the other. Obviously, this made no sense to me whatsoever.
I removed and reinserted the micro memory card/adapter twice freshly loading on both occasions. This morning, I attempted to add some more music to the very same micro memory card, and I got a response that the card was “write protected”. So, a few days ago I added some MP3 music to my MP3 player no problem. As in standard practice to some of you, and in order to either add MP3 files to my MP3 player or if I want to download video files from my drone, I use an adapter in order to size the micro card up in order to fit the slot in my desktop tower. I am using SanDisk Micro SDXC memory cards in one of my MP3 players, and also in one of my drones. It may help just a few of those that are experiencing this write-protected problem. Having said that, I think I should pass along something that happened to me, earlier today. First, let me mention that my forensic computer skills are average at best.
