Issues supplying power to HDD

@madmodder123 can you post pics of your setup. I would like a good idea of what you have with case and all so i can give you the best suggestion.

I don't mind switching out the PSU for another one, but space is pretty limited...
I could also remove the plastic barrier between the PSU and middle of the console if needed.
De-soldering USB connectors and hard wiring them is no problem either. -
I was thinking of just buying one of these:

@madmodder123 i would buy this. It is a powered rockband usb hub. But dont buy one that isnt self powered. Some dont use a power supply. You need one that does. I would then run power straight from the power supply to this. I use one of these. When there is no signal from the pi it will shut off the hard drive attached to it. Even with power going from the power supply straight to this hub. I split the power to my playstation raspberry pi and it works great.

So I had my project all set up using an external HDD which ran perfectly with no lightning bolt when it was plugged and powered by the Pi, I then upgraded to the internal HDD listed above because it was slimmer.
I removed the board from the PSU listed above and have it all wired up.3'5 inch harddisks need 12v USB is only 5v bro that is why it doesn't work. Thats also a reason why external 3.5inch HD's always come with a power supply. The harddisk in your case needs a separate 12v supply. Even if you're using a USB hub it won't matter, it still needs 12v.The harddisks without power supply are the smaller ones (2.5inch), you can feed them directly trough USB. In the past I experimented with this and I noticed that you need a short USB cable, for some reason the harddisk wont get enough of juice if you use a long USB cable.
You need to use a smaller HD of 2.5inch. You can run it directly via the Pi, but you need to see how much amps it's using. If you do so you also need to count the amps of the peripherals which are connected to the Pi (controllers, Bluetooth USB dongle etc.) Lets say;
You have one 2.5' USB harddisk which needs 1000mA
You have two USB controller which need 700mA per controller so it is 1400mAIn total you would need a power supply of 2400mA, your current power supply is 2500mA so it should be fine.
EDIT: ignore this post.

@PetroRie where did you see a 3.5" hdd? I looked at all his images and they are all 2.5".

Woops, on the Amazon link I clicked on the picture below quickly which led me to an another page. Shame on me :(
The drive of TS uses 800mA. TS also said he had the lightning bolt symbol, I really wonder if his power supply really has an output of 2500mA. I think its safely to say that if you get that lighting bold icon you need to use a power supply which delivers more than 2500mA

An option that you can use is a DC-DC buck converter such as the one found at:
This one is nice as it has current and voltage adjustments with onboard display. If you go this route, you would want to get a 12v power supply for your input to down convert to 5v. (I went 12v @ 5A supply) Another design note is to make sure that the wire coming out of the buck converter for your 5v needs meet your current requirements (ie minimum 22 gauge if you are designing the circuit for 5A max draw on the buck... When I worked on my NES R2-D2 build, I was constantly getting the lightning bolt indicator (even when i shortened the cables). When I got this buck to power everything and adjusted the voltage output, I didnt have any further issues with the lightning bolt indicator. You can see pics of it at:

Let me know if you have any questions and ill try to answer to the best of my knowledge.

It turned out that I was just using a cheap ass micro USB cable, when I replaced it with a quality one the issue stopped happening, thanks anyways guys
