Accessing SD card storage
Has anyone had trouble accessing the SD card in order to store backup, or to move files? Whenever I run MyBackupPro, I select the option to store on SD card, but it ends up in internal storage of the device. Same with Gobackup. I can access the SD drive externally when I plug into a computer, so i can see that the backups are not there. As far as I can tell, the only way to add things to the SD card is to add it while connected to a PC in Mass Storage mode.
