No, you didn't.
you said you used wii backup manager
you didn't tell us if you used it properly or not.
Lot of people don't understand how they are supposed to use that program, and manually choose the folder where to "convert" the game to wbfs, while they should choose the "transfer to Drive1" option instead.
So, if I imagine you used it properly, you have the correct cIOS, you used r1271 and you said you are now using HDD instead of flashdrive... the only issue left is wrong USB Port.
Or the very rare "read only" (which happens more often when not using Wiibackupmanager properly too)
and yes, the suggestion from Alexander is good : try another loader to see if the problem is the application/settings or your setup/hardware.
