Try getting an internal USB 2.0 PCI card.. that should work.. the front USB ports are not adequate you can buy one here.

Good luck!

I would like to download the info on an old extermal hard drive. when plugging the iomega into my mac book pro - it says that USB devices disabled due to to much power to re-enable USB devices ... this...


Some older external hard drives required special USB cables with two plug-ins. This was not for the sake of data transfer, but because they needed more power than a single USB port could provide. Some older units even went so far as to have the laptop-type "brick" power supply since they needed so much power. This is probably what is wrong here. Your Mac Book probably doesn't have the current to handle the drive on the port and is protecting itself. Some units have one or two high-power USB ports. This may work if you have one. Otherwise, you'll need to download the drive another way.

I know there is data on my phr-250a mcally external hard drive but it's showing empty folder


Leave it connected to your computer and try a restart.
If the folder is still showing as empty, power down the computer then disconnect the external drive.
Power on the computer and connect the external hard drive to a different usb port.
I had this exact problem with a 1000 Gb external drive that was full of movies and music. I thought it had all been lost .. After 2-3 days and repeated attempts of restarts and power-downs/different usb ports it suddenly was recognised again and has worked perfectly since

External drive not picked up on computer


External hard drives not only provide additional storage space on a computer system but also allow data to be conveniently transported from one computer to another.


These drives typically plug right in to a port on the computer and function without any additional setup; however, if you are running into trouble where your external hard drive is not being detected, you must troubleshoot the situation to determine why the drive appears to be missing.


Check the USB connection running from the hard drive to your computer.

If the USB cable is not seated securely in the port, the computer will not detect the external drive.


Disconnect the USB cable from the computer and plug it into a different USB port. Occasionally, a USB port will fail to function with some hardware and changing the USB connection may correct this issue.


Switch from a USB to a Firewire cable connection, if possible.

The USB port on the hard drive may have died; if so, changing to a Firewire connection will resolve this issue.


Install the driver for the external device from the installation disc provided with the product. Older computer systems may require you to manually install this driver.


After inserting the installation CD, follow the prompts from the installation wizard to install the driver on your computer.


Restart the computer.

If you connected the external drive while the computer is powered down, it may not recognize the device when you turn on the computer.


After restarting the computer, connect the external drive to the system.

The drive should now be detected by your operating system.


Connect the external hard drive to a power source and then plug it into your PC computer using a USB or Firewire cable.


Log on to your PC computer using an account with administrative privileges.

Open the Start menu and click on the "Control Panel" icon.


Open the "Administrative Tools" folder and then double-click on the "Computer Management" icon.


Select "Disk Management" from the list of options on left side of the window.


Right-click on the drive you want your computer to recognize and select "Change Drive Letter and Paths."


Select a drive letter for the external hard drive to be recognized as and click "OK."

The drive will now appear in My Computer.


Hope this helps.

Computer not recognizing MyBook when plugged in


Have a look at this article on external hard disk troubleshooting. Could be that you need to delete the USB root hub devices in the Device Manager to force Windows to recognize the device.

My external hard drive is not being recognized by my computer.


Try using another USB cable or different port on your PC. It also may be that it needs external power, Check to see if its plugged in to the wall, if it is, it may be that you need a new power supply.

My two front usb ports cant read usb hard drives


Some external USB drives require external power sources. Typically this is done either with an external power supply that connects to the drive or a second USB cable that connects to the drive and a second usb port on the pc. I have even seen one drive that comes with a Y cable. one end goes to the drive and the 2 usb plugs go to the pc.

I recently purchased an external hard drive, and how do connect it to my computer.


External Hard Drive is mostly of the USB interfacing type. If urs one is the same, then it is just as simple as plugging in a pen drive in the USB port. If it has external power supplies then u can easily figure out how to connect. There are two parts in the power supply (if external power supply cable is provided), 3-pin main power supply connector and other is the adapter which goes to the external hard drive.plug in the other end of the adapter into the hard drive (there is a hole in it). connect the main power cable to the adapter extension. now for the usb Hard Drive, connect the USB cable to the USB port of the computer. Switch on the power supply to the Hard drive and u r ready to use ur brand new External Hard Drive. If it is a Firewire interfacing one then u may need to open the CPU box, and then connect the firewire connector on to the motherboard firewire port. It is easy to identify, it is a red colored port/connector.

Simpletech 500 gb external hard drive


There is a power consumption work-around untill a Y usb wire can be purchased; the main power cable must still be used at all times but this workaround should only remain temporary!!!
Simpletech should have included this so laptop users could use the drive as their capacity is better than the packaged slimmer simpletech portable backup drives for laptops, which does include the Y cable....
1) unplug usb while powered and unknown hardware is present on laptop...
2) turn power switch off from the external HDD...
3) return power switch to on from the external HDD...
4) plug in usb connection to laptop...
Autoplay should read from external HDD!!!
**** Save some $$$ and buy a Y shaped cable to provide sufficient amount of power from laptop usb
ports, cause it's necessary to use 2 of your ports to provide power in addition to the main power from HDD to wall****

Is my hard broken before i have got a chance to even use it?


However rare, it is possible that you have a dead hard drive. I would try the hard drive on a different computer (one that has a known good set of USB ports). If that still does not work, take it back to where you got it and get a refund/replacement.

A couple of things you can look at:

1) Do you hear/feel the hard drive "spin-up" when you first turn it on ?

2) Does the hard drive come with an external power supply ? If so, it could be just the power supply that is shot. Check for tell-tale LEDs that would say whether it's working or not.

3) Have you tried different USB cables/USB ports ? Sometimes the front ports do not have enough juice to power a hard drive (if it's drawing power off the USB port). Sometimes switching to a USB port on the back of your computer is enough to solve the problem.

4) Make sure to eliminate as many superfluous components you can from your testing: don't plug the hard into a USB hub, plug it directly into an motherboard USB port (as mentioned above, the ones on the back).


Hope this helps.
