First time imaging an usb flash device

This is the first attempt to create an image of an flash usb.


So how to start?
 

• First plug your device into your machine and in the next step you have to find out where it is mounted. After a few minutes google, i came up with following comand:
•  sudo fdisk -l

•  Then create a md5 checksum of the device
• sudo md5sum <location of device>

• now we have the mountpoint (it is the "device" column) and can start the actuall imagen. Therefore linux has a very good tool called dd
• sudo dd if=<location of device> of=<where you want it>name.dd

This could take some time, dependend on your device size.

• finally create again a md5 checksum, but now from the image. If the two checksums are matching, the created image is a exact copy of the original device.
