Do you have other SD cards? if so, have you tried another SD card? It's possible that the reader's write-protection mechanism is broken.

Also, (assuming you're using a built-in SD card reader) have you tried an external USB SD card reader on the same computer and the same SD card?

My SD to IDE adapter only works when the card is write protected(that slide thingy on the side of the card) and i can write to it while using the adapter, now when i go back to my modern pc with a sd card reader it will require me to change it to write.

thank you guys.

My IDE adapter works with unprotected card, so I kept the switch on NOT-protected.

I didn't try external readers though! Trying.... it works!

So, other SD card with the internal laptop reader works!
The affected SD card works with the USB external reader.

Now who can explain that! 🤣
If it was a problem of the computer's reader, it wouldn't have worked with the other SD card, but it does.
If it was a problem of the SD card, it wouldn't have worked with the external USB reader, but it does.
Is it possible it's a problem of a specific combination of a specific reader + a specific card (which in the past worked!!!)???

Just discovered a couple of days ago my SD card reader is dead under Win10 as well (doesn't even show up in dev manager) but boot using Linux and everything works so both SD card and reader are fine. I assume its some weirdness under Win10 (originally it was a Win7 box) which I can't fathom either. Just one more reason for my being determined to make my next machine a Linux box religating Windows to a VM.

thanks for the info!
Wow, if Windows is so moody natively, I can't imagine what are you gonna undergo if you put it in a VM! 😳

Running in a VM appears to be painless enough using VirtualBox (installed NT4 up to 8.1 client, NT4 to 2016 server) unless you try using windows deployment services then it starts whining about having no nic drivers so it can't install (minor annoyance, just experimenting (yes I know I should add the nic drivers to the wim file but I wasn't in the mood for that)).

Not that I would be using it to access removable media like sd cards in that scenario anyway, it would simply be there for legacy applications.

I see. You know the drill much better than me!

Thanks and all the best! (or should I say, all the beast 🤣)
