Use Your USB Charger on your HDD
Being an IT person myself, i got to find that many have their External HDD gathering dust just because they lost that Blue/Green cable that come with HDD.
Stop worrying, use your Blackbery USB charger or Samsung to access your HDD. If you look at the HDD port, the other part looks like a port on your smart phone, the other square-like port is for USB3 compatibility so you don’t really need it.
All the best
