If your system unable to determine the filesystem type, change it accordingly to the USB drive’s filesystem (e.g. vfat or ntfs or ext2 or ext3). If you know the filesystem of the USB drive or the system unable to determine the correct filesystem, the -t option can be used to the filesystem type of the USB device: mount -t vfat /dev/sda1 /mnt/usb (for vFAT filesystem) mount -t ntfs /dev/sda1 /mnt/usb (for NTFS filesystem)
