"A USB device is drawing too much power..." External Harddrive

My 15" Macbook Pro, OS X, 10.6.8, 2GHz Intel Core i7, 4GB memory keeps booting my 1 TB Seagate external harddrive off because it is drawing too much energy. It's done this repeatedly for about two weeks, and now it won't appear on the desktop (while it still whirs when I attach it and the LED comes on). I checked how much energy it's drawing in the System Profiler. 500, then very little after I restarted both machines, and then too much again. I tried connecting it with an identical harddrive's cable (my housemate has the same model), and it wouldn't register then, either.
...I suspect it's the harddrive as opposed to my MBP! Or I hope it is, and not a problem with my USB ports or anything like that. I'm surprised because the Seagate is connected to the mains... But if it is the Mac, how would I go about checking to know if it is? (My Wacom Bamboo is working fine.)
Anyone with any ideas, suggestions? Anything else I need to inform you guys of?

:-) use your room mate's and do it!
pretty old drive, is it makeing clicking noises? try re repairting it before you go erasing but I think yoru system is giving you some sound advice. but I would go further in saying it's either too full or too old and is on it's last legs.
If you are afraid you're going to be loosing some important data that you haven't backed up get DiskWarrior as this has saved me from loosing my hair a few years back when my HDD crashed.

if you do get this, be sure to be picky on the things you keep as it will not always work and it sounds like your hard drive is on it's last legs. Imagine a door slowly closing everytime it spins up.

Error message (Because a USB device was drawing too much power)

Hi Everyone,
Bought recently a new macbook pro 13 inch with Retina display with 120 GB flash drive.
Connected a non-apple CD drive to my macbook and after that started receiving this message: "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
initially I was receiving this message after I switch on my macbook but now after every 30 seconds this message pops up although I never connected anything to my macbook through its USB ports.
Will highly appreciate for your help on how to get rid of this problem.
Regards
Homayun

Try resetting the SMC
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

I don't have anything else plugged into my MBP, so I am confused as to what's going on. This problem has never happened before. MBP is less than a year old - about 9 months old. HELP

When I plug in my son's iPad I get this message "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled." I only have one charger for this iPad all my other chargers are for iPhone 4s. I have pluggerd it in different outlets around the house and the iPad will not charge. When I plugged it on my lap top to back it up it gave me the warning message. HELP!!

I have the same problem on my Air. The message first came up while my iPhone was connected to it for some time. Since then, it pops up ALL THE TIME, whithout anything being connected to the USB port, at what appear to be random intervals that vary between about one hour and a few seconds. I have tried resetting the SMC and the PRAM, but no results. A quick search revealed that thousands of users are facing this problem, but Apple has yet to provide a solution. Please help!

"Because a USB device was drawing too much power from your computer..." error withOUT any USB device

Hi,
I am getting this error since recently when I am using my MBP:
"Because a USB device was drawing too much power from your computer..."
The 'funny' thing: there is no USB device attached to the computer (only power and monitor cables).
Why is this happening and what could I do about it?
Appreciate your ideas?

It's probably an internal hardware fault, but you can try this:

If you just bought the iMac and the Sjuperdrive take the superdrive back and get a refund. The by any other brand external DVD drive that connects by USB and try that. Most come with a Y USB cable to allow you to connect to 2 USB ports to supply enogh power to the drive IF Needed.
Or take both back and get a refund on both, you have 14 days to return it no questions asked, and buy another iMac and some other brand external DVD drive.

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled?
What do I do?

Not Charge
- See:
iPod touch: Hardware troubleshooting
- Try another cable. Some 5G iPods were shipped with Lightning cable that were either initially defective or failed after short use. One symptom of a bad Lightning cable is the message you are getting.
- Try another charging source
- Inspect the dock connector on the iPod for bent or missing contacts, foreign material, corroded contacts, broken, missing or cracked plastic.
- Make an appointment at the Genius Bar of an Apple store.

Because a USB device was drawing too much power from your computer - bla, b

In the last week or so, my iMac (Intel CoreDuo) started displaying an error message every 30 seconds saying "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled", followed by some other useless "explanations" (which BTW can't even be copy/pasted). This has happened before (for about a year now) at every startup, but that was more acceptable; now that the message comes every 30 seconds it renders this machine unusable.
I tried it with or without any USB accessories attached, with or without powered hubs attached, I reset the PRAM and SMC and reinstalled the OS twice. The only option I have left is to trow this machine out and buy a new one (believe me, it's not going to be a Mac).
This shows not only the lack of quality of the hardware (crappy logic board and USB ports) but also a complete disregard for the annoyance these constant popping messages create to the end user when designing the OS. Just while writing this message I had to press the OK button about 10 times. It's AWFUL!!!

Hi cimula. before you turn to the extremes have you tried reinstalling snow leopard. maybe you had a problem occur when it was originally installed and is missing a driver or something. also take it to an apple store if possible. take everything needed to run the imac and show one of the geniuses the problem and 90% of the time if you are nice and calm they will gladly help and diagnose the problem even if it is out of warranty. no promises it will be free it could be a hardware malfuntion. just dont force your self back to pc once all of the problems are gone you will love it again. i switched from pc which i had been using my whole life after a friend showed me his macbook and have never looked back. of course once and a while there will an error, problem or whatever but is it worth switching to a pc which has to have a security program running 24/7 to stay alive and sucking up all of the cpu and slowing you down? hope i am helping Dean

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

Unplug whatever other devices you also have plugged into USB, and try again. Better not to plug the iPhone into a USB hub.

Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. - This is what shows up sometimes even when no USB is connected. What could be the reason?

Try a different USB cord, seen this many many times, its highly likely a damaged USB cord.
Restart the computer to redefine Port definition. If still a problem
