Have bought the bag for my small hard drive from WD "MyPassport". It fits perfectly into the cable without slipping and is also easily its place in the "pocket" without squeezing it costly need or like. Since the bag has a hardcover, I must not be afraid to make any damage my hard flap when they are on with me is going on tour times. The quality also makes a very good impression and has by now 2.5 years neither traces nor lead.
