the third option can be described in another way.
insert usb stick into your computer.
do:
cat /etc/mtab/dev/sda3 / ext4 rw 0 0
/dev/sdb1 /media/USB-flash-drive vfat rw,nosuid,nodev,uhelper=udisks,uid=1000,gid=100,shortname=mixed,dmask=0077,utf8=1,showexec 0 0
See USB flash drive has a mounted partition /dev/sdb1 means the device /dev /sdb
bs option indicates how many megabytes will be read and written per second
bs option is simple.
if you know the approximate speed record on the usb flash drive, specify it in the megabytes. such bs=1M, bs=2M, bs=3M
dd if=Pardus-2011-i686.iso of=/dev/sdb bs=2M
dd if=Macpup520.iso of=/dev/sdb bs=2M
But I still recommend using the
first method.Then you will not be mistaken for a device to burn an image.
