300gb no power

Have you tried a differnt usb cable if that dos not do it get back with me and I will walk you though checking it out

Could be a bad transformer on the power supply or a bad drive. You could check the voltage coming from the transformer and verify that it is the proper voltage using a fluke meter. You could also dis-assemble the hard drive housing and try installing it in the computer and check if it is working. If you install it in the computer and the drive is not found then the drive is probably bad. If the drive works in the computer then get a new transformer.

Solution:
First, disconnect the power cable from the back of the external hard drive:
If the power supply LED continues to blink:

1. Connect the power supply to a different outlet (or instead of connecting to a power strip, connect directly to an outlet in the wall).
   
   
2. If the power supply continues to blink after changing outlets, this indicates that the power supply is defective and needs to be replaced.
   
   
3. If the power supply stays solid, then reconnect to the external hard drive and see if the drive spins.

You could buy another drive with the same specs and replace the circut underneath the drive with the circut from the new drive, then try it in your new enclosure

THINGS TO TRY

1. Try restarting the console.
2. If restarting the console does not resolve the behavior, follow these steps:
   • Turn the console off.
   • Unplug all the power and AV cables from the console.
   • Unplug the power cord from the wall socket.
   • Firmly reconnect all the cables.
   • Turn on the console.
3. If these steps do not resolve the behavior, turn the console off, remove the hard drive, and then turn on the console. If the 3x Red LED error light is no longer displayed, turn the console off, re-attach the hard drive, and then turn on the console.
4. Also examine the lights on the power supply. When you turn on the console, the power supply light should illuminate green even if the three lights on the RoL flash red.

Hello.
Most likely this is an output problem. But I have had 1 PS3 that had a bad hard drive and it wouldn't even load to the XMB. So try another hard drive and see if that works. Even a swift smack to the old one may work. If that doesn't work try the video out reset.

Reset the Video Output Settings. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light to --> green light --> then back to red light) This will ensure that you have held down the On/Off button long enough to reset the Video Output Settings. Once you turn it back on, it should work fine.

Hope this helps. Good luck!

Hi,

The USB Isn,t supplying/providing enough Power to the device.
Search e-bay or similar for a 2 into 1 USB Cable.
Then power the unit with 2 USB Ports on the Computer.
2 x USB Into 2 x Sockets On P.C. 1 x Into Device Drive.
This will be enough power to operate the Device Correctly.

I,ve done this on several external Drives, never failed for Me.

Check cmos to see if usb ports are enabled? If Windos 2000 you need a usb driver disk.

usb cable provides power to your hard drive.

try to use new cable.

hopes it works.

pls. confirm
