How to use Linux dd with USB drive
The USB Drive needs to be unmounted. If the USB Drive is automatically mounted, unmount it.
Type dmesg to see what device to use to access the USB Drive.
Example: … [sdc] Attached SCSI removable device
This mean the USB drive is /dev/sdc
Erase the USB drive by running the following command:
dd if=/dev/zero of=/dev/sdc bs=65536 count=10000
Extract the Name_Of_The_File.dd to the USB Drive:
dd if=Name_Of_The_File.dd of=/dev/sdc
