I have a .Net Micro Framework app that is failing to write bytes to a microSD card. When I take the card out of the device and look at it on my PC using a microSD to SD adapter the PC cannot write to the device as it appears to be locked. I'm trying to work out if the lock is a faulty adapter (the switch on the side of the adapter is set to the unlocked position) or the sate of the microSD card itself.
MicroSD cards have no visible way of locking and unlocking them but is there any setting in the card itself that locks it?
I have tried searching but most threads I can find (e.g. this one and this one, to choose two SO ones) talk about the adapter. Is there locking in the microSD specification?
