I need to read and write to an USB mounted volume at raw level. It's a SD card in a card reader.
It has a custom file format I made- and a custom-made electronic device writes to it/reads from it. Now I need to make this filesystem accesible to the computer (although not through explorer.exe).
I need to make an app which will show the files and read/write/delete them. I haven't found anything like this by googling but I know it's possible - software like winHex can do it.
