SD Card Not Accessible!
SD card D:\ is not accessible. Incorrect function
Hello, I receive the above error when I try to access my SD card on the PC. The SD card was working fine until I moved some music on it. I have tried some possible solutions found online, but none of them work, for example:
I have tried using this command "chkdsk m: /r", didnt work.
I have tried changing the drive letter, but it didn't work.
I have tried formatting, but nothing happens when I right-click the SD card and choose format.
I have also tried to use the SD card on my laptop, but it does not even get detected
I would appreciate your help on this.
Waiting for your response.
Kind regards

Cannot access SD Cards on my PC
When I try to access SD Cards on my PC, I get the error "E:\ is not accessible. Access is denied.". This happens on any SD Card I own, so it's not the SD Card's fault. I can also access all the tested SD Cards on all my other devices without any problem, and I can access them using third-party file explorers, such as Total Commander, as long as they have admin privileges. So the problem is Windows 10 in this case. Has anyone experienced this problem before and knows how to solve it?
