I've been trying to copy files off my camera's SD card in the keyboard slot to the internal storage of my TF201. There are several hundred files of about 5Mb each. I've tried using the inbuilt file manager and also the Linux copy command in terminal emulator. The result is the same, the file copy terminates ("paste failed" in file manager, "file not found" in copy command) after sometimes only 3 or 4 files and the Camera's SD card becomes unmounted. Removing it and reinserting it allows the copy to be restarted manually but the same issue occurs. Is this an issue with Android ICS or with the ASUS and does anyone else have this issue?
