Hi, this happened to my Raspberry Pi too. The number on the white square looks like 16/11 (it is hard to read though).
I'll send the other info next time I boot it up.
I am not sure if I might have pulled the Micro SD card out instead of remembering to push it in and let it pop out. Unlike in a phone, there is room to reach behind and get one's fingernail behind that pronounced ridge.
I heard elsewhere that force pulling it out does not damage the mechanism (it just pulls out without spring pressure), but if this is wrong then what happened is probably my fault.
However my main point is that I am not going to request any replacement, rather, I am going to do the fix of putting in a folded up piece of paper on the side of the socket without the contacts before pushing it in.. In fact I have done this already and it works fine.
I looked at some of the almost angry comments from 2014 when this happened to some people, and they really surprised me.
My own overall experience with this has been really wonderful.
How many times have I had to hear that hateful Microsoft alert warning you that your formatting will be destroyed if you save in txt format, when using wordpad, or using notepad when it gives only one level of undo. And many many other horrible dishonest things that Microsoft does, and Google does, and Adobe and all the other corporations.
Using this has been such a relief, and it is because the Raspberry pi is a labour of love, it is done as a charity.
And, it is a great computer! For stuff I do (even scientific computing needing a lot of processing power, or trying to show stuff to kids with not a lot of patience always) this has been as good as any new PC.
I am seriously thinking of switching to using a Raspberry Pi as my main computing device, once I get up to speed with preventing too much writing on the SD card, so it can be in read-only mode.
The danger, in my mind, is if industries get hold of these and start just using them as ordinary devices in the competitive market, say, to control robots manufacturing cars. As a basic component in engineering, rather than a teaching tool.
Because, truthfully, business leads to destruction, and this enterprise is way more than any business, it means way more than that.
I view it as a charity and no way am I going to ask for a new device to be sent to me, I'll keep this one, and hope I can find some way of explaining to the wider world what a wonderful addition to the open source community it can be.
