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

I was doing some file transfer from my Macbook Pro to the external harddisk. Both laptop and harddisk was placed on a solid table and nothing was moving nor was the transfer disturbed. Just suddenly a warning message flashed on the screen and the connection between harddisk and laptop was stopped. The message, +++++ Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled. When you disconnect the device drawing too much power, your other USB devices will be enabled again. ++++++ Have tried connecting the harddisk to other laptops and computers but same message. Harddisk wasn't spinning went I connect. Same message appears. Haven't tried with a PC. Have tried connecting directly through harddisk internal USB cable or through the given USB connector. Not working as well. Appreciate some help here. Thanks so much!

SOURCE: We understand that your problem is: hello i was

The external storage device has several major components:
* USB cable
* external power-supply
* disk-drive inside the enclosure
* USB-to-disk-drive adapter inside the enclosure.
Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.
Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.
Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.
Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.
Buy a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.
Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive.

USB drawing too much power. I have a Canon MP460 all-in-one printer and a MacBook Pro on Snow Leopard. I just bought a new USB printer cable because my past two were not working in respect to this issue. I...


It may very well be drawing too much power from your laptop. These are fairly intolerant of devices that draw higher current like printers and some hard drives. You may need to get a small USB Self-powered hub. These are USB hub/splitters that have their own power supplies. These usually provide and tolerate higher power draw. To test, if you can connect the same printer to a desktop, you will likely see it works fine.

My Hitachi Touro 4TB external hard drive get stuck every time I try to transfer large files. How do I fix that? The format is NTFS and the files are 4g and up.



External hard drives are popular portable storage devices because they allow you to back up files such as documents, music and videos, and transfer files from one computer to another. While external hard drives vary in storage capacity, they are ideal for storing large files such as videos and animations. Files of this nature consume volumes of hard drive and memory space and are best stored in external hard drives. Whether you are using Windows or Mac OSX, transfer large memory consuming files to your external hard drive quickly and safely. Connect your external hard drive to your computer using the Firewire or USB cable that came with your portable storage device. If its transferring to slow the usb lead might be at fault or you might need a usb 3 card which makes data transfers much faster USB 3 card will provide more power when needed to the device to gain maximum throughput and conserve power when the device is connected but is idling http://blog.premiumusb.com/2010/09/usb-2-0-vs-usb-3-0/ these can be purchased on Ebay cheap and easy to install http://www.ebay.com.au/itm/PCI-e-PCI-Express-USB3-0-Card-new-NEC-720200AF1-chipset-/330608109325?pt=LH_DefaultDomain_0&hash=item4cf9c7670d for roughly $9 or $10free postage Power on your drive. Some external hard drives do not have a power button, because your computer powers them on automatically using the Firewire or USB cable. Click the Windows "Start" orb and click "Computer" or "My Computer" to launch Windows Explorer if you are using a Windows PC. You should see your external hard drive in the "Drives" section next to the "Local drive (C:)" drive. If you are using a Mac, you should see your external hard drive on the desktop. Double-click your external hard drive to open its hard disk window. If you have any content on your external hard drive, you should see it in this window. Drag files from your computer to your external hard disk's window. Because you are uploading large files, make sure their memory s do not exceed your drive's total memory. Your computer shows a status bar displaying the upload progress for each file you are transferring to your drive. The upload time varies depending on the of the file. Close the hard disk window when you finish uploading the files you want to store, and then click the "Safely Remove Hardware" icon on the System Tray next to the clock, if you are using Windows. The hardware removal window launches. Click your external hard drive's icon in the hardware removal window, and then click "Stop." When prompted, disconnect your external hard drive from your computer. Drag your external hard drive's icon from the desktop to the trash bin on the dock if you are using a Mac. Disconnect your drive from your computer. If you right click in the bottom toolbar select applications to see whats running at the time when transferring the files might be a virus or malware if you see something running that should not be select end now also processes to see what ticking over in the background

Hope this helps b>

My computer says the USB port connected to my mp3 is drawing too much power and has shut down the USB port. How do I get around this? I have a MacBook Pro.


It look that your player is drawing too much current from your Macbook Pro: it is rather unusual nowadays but does happen even with some USB external 2.5in drives!
Solutions:
1) Buy a USB Power Adapter Y cable that plugs into 2 usb ports on your Computer an thus allows double the current (shop around as they are expensive on Amazon but pretty cheap on Ebay)
2) Plug your player via a 'Powered' USB Hub that can provide higher current (from its 'own AC/DC power pack') to each USB port on the Hub

Hioe it helps!

WD External won't connect to MacBook Pro


If the computer switched off before writing to the hdd with a TOC or index file, all your files are there they are not recognised by your computer. You will need recovery software to recover your files.

Can't get photos from MAC to load to Digital Photo Frame




To connect to a Macintosh computer: 
1 Plug in and turn on the digital picture frame. 


2 Connect the small end of the usb cable to the usb port on the side of the digital picture frame. 


3 Connect the larger end of the usb cable to a USB port on your Macintosh computer. The Macintosh will recognize the digital picture frame as an external storage device, and an icon will appear representing the device.


4 Drag and drop your photos on to the icon...


5. After you finish, press the eject button, and disconnect the usb cable once the icon has dissappeared


If there is still a problem, try restarting the macbook. and make sure no other programs are running in the background that may interfere with the process. Also, make sure the laptop is plugged in, or the battery power is sufficient.


Hope this helps!
