You shouldn't mount the disk.
The command is something like
cp /dev/sda  /this/file/will/be/big
Note that sda does not end in a digit.
It refers to the entire drive, not any particular partition.
You might need hdb or something instead of sda,
depending on the drive and its place in the pecking order.
The copy will take a while.
dd, with a different syntax, will work also.
