One of the hard disks in my PC which is shared in the network, but whatever devise (an Media Player [Minix U1], an android phone, a tablet, or a smart TV) I use, I am asked for a username and password, and I have not set username and password.... By the way, my PC is on Windows 7 64bit...

Tried to look for some solution and I went to view homegroup password and tried to use and also change it, but I am left with the query: what is my "username"? For the username, I tried my PC account name, but the same problem... there is an error of not having the correct "username" and/or "password."

I also tried "turn off password protected sharing," but still the same, I am asked to enter "username" and "password"... Pls help...
