Hello

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards
Andrea

Pc d'ont reconize this drive


Primary or external ???.....
A USB hard drive is a portable external storage device that works just like a conventional hard drive.
The device is simply plugged into a USB port on your computer as you would connect a flash drive.
Unlike a flash drive, however, a USB hard drive can store a much larger amount of data.
If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely.
Or even get a usb 3 lead.
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/
Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7).
The USB device should be listed as "removable disk" once it is plugged into the computer.
If it is not listed among the available drives on your computer, proceed to the next step.
Ensure that the data cable is working properly.
Sometimes they become faulty due to overstretching age or heavy objects sitting on top of them.
Try another USB cable if you have one available.
Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive.
Reboot the computer if the USB hard drive is still not recognized.
Plug the USB cable into another USB port and check to see if the device is detected.
If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port.
If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem.
Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager."
For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter."
Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives."
If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears.
Windows 7
First, please disconnect all USB devices and then perform the following steps:
Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.
In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.
If the hard drive that has failed is the same one that you are trying to recover from might the reason that you are getting this error.
This could be an issue where the part of the hard drive you are trying to access is corrupt and not accessible which would explain the reason that it would let you access the other partition.
Now I have seen cases where Malware can break the link of a Hard Drive.
So let's try a couple of steps.
Let's go back in to "Disk Management"
Lets right click on the partition that you are not able to access and select "Change Drive Letter and Paths"
Now try selecting a new Drive Letter.
This will restore the path if it has been broken.
The external hard drive may have been detected but the device is not working properly.
If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced.

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.

The pc does not detect the usb drive, the usb flashes. But nothing comes up


Make sure it is inserted all the way into the usb port. If nothing comes up, this doesn't mean it isn't connected, it just means autoplay isn't on. Once it is plugged in, go to the start menu > computer. This will open a folder with all your drives, both internal and external. Double click on your flash drive's icon to open it.
