Printing Foreign Directory

[Jordan Rudderham]

	I'm trying to print a foreign directory (removable HDD). The methods
I've seen for printing out the list of items in a directory is ls >
file.txt. But I can't seem to be able to access my removable hdd in the
terminal (I'm ignorant of where I can find it). The secondary question
to this is: is there any other way to print a list of the items in a
directory that also prints the items in sub-directories of that
directories?
