Interesting, sounds very similar but not as extreme as my issue.
Cables may be an issue but just because it works with a B does not mean it's good enough for B+ - and only real way to tell is trial and error I think, everything is much too small to try measuring. PSUs similar, and what it says on the tin is not necessarily what's inside!
Do try any alternatives you have, they are the most likely cause IMO.
I later did the raspi-update command to try the max_usb_current=1 setting in the config.txt and after that I got a small rainbow box in the right hand side anytime I plugged in the HD.
That square is an under-voltage warning.
I was also using a wired hub for the HD and a wired xbox360 controller but those were drawing from the hub of course.
I think there is still some current draw even using a powered hub, how much may depend on its design. Others will know more and correct me if I'm wrong I'm sure.
With the HD plugged in on NOOBS Raspbian one setting (safe_mode_gpio=4) the red PWR led blinked at a constant interval. On the other (max_usb_current=1) no red led was present and the green ACT led was faint but blinking in rapid succession
The red LED should be lit and steady. The only time mine is completely unlit is when unpowered.
anytime I've come to you guys before with questions I feel like I've been misconstrued and made to feel rather stupid.
Ah yes, the internet
compatiblity issue with HDs as well, some might draw more power than others.
That may depend on how you intend to use them. Through a powered hub should
be no big issue assuming the hub can cope.
If you want to use it for the OS I believe it will need to plugged directly in to the B+ in which case there may be power issues but I have read reports that others have done it and that is what I intend with mine. Hope to get to that later today - I don't do youtube.
