When I entered the command in command prompt (MSDOS) âCHKDSK D:â or âCHKDSK D: f/ x/ r/â I would get this message âcannot open volume for direct accessâ. I keep getting the message that the drive malfunctioned when I first plug it in.
Colonel (abbreviated Col. , Col or COL and pronounced /ËkÉrnÉl/ , similar to kernel) is a senior military officer rank below the general officer ranks. However, in some small military forces, such as those of Iceland or the Vatican, colonel is the highest rank.
It is also used in some police forces and other paramilitary rank structures. A colonel was typically in charge of a regiment in an army, especially in Great Britain; but typically as of 2012 a colonel is the commander of a brigade or regiment in the U.S. Army or Marine Corps, and of a group or wing in the US Air Force.
