My light stopped working completely, and the unit was not recognized by the PC. I removed the drive fron the case and installed in my computer. Works perfectly.

Make sure you have the power adapter that came with the unit. That was the problem with mine. Now it works fine.

This may sound silly,but sometimes if you put the drive in the freezer overnight it will work long enough for you to retrieve your data.Make sure you are ready to copy the data to another as it will likely fail again once it warms up.

Hi,

This generally means you have a hardware failure in the drive or enclosure. The simplest way to test which is to have a hardware tech move the drive into a new enclosure and see if it works.

This will void your warranty if you do it, so, if the drive is under warranty and there are no files you consider valuable on the drive, call the manufacturer for warranty support.

If you value the data more than the drive is worth then take it to your local hardware vendor and ask them to test the hard drive in a new enclosure. Good odds it will work this way but if not you may need the help of a data recovery specialist.

In North America I use Armor-IT, if you are in a different region and the new enclosure fails to garner results, comment back with your region(Country, State, City) and I will supply you with the closest reputable facility.

SOURCE: When I supply power to the hard drive, the green light flashes.

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and OTHER devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.

USB hard drives should be treated with extreme care.
This is a real hard drive ! and knocks and bumps can quite literally kill them.

It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.

Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.
Known as "The Click Of Death"

If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.

A blue and red flashing light and won't connect to 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.

LED light has gone out

Lights up blue when the Drive is powered on. Flashes red when reading or writing data. It was just stuck between color as it does not flash green,red-blue make green. Contact the company and see if it is under warranty, if not see if they will send you a new light, because
if it is not under warranty,it does not matter if you open it.

All that is inside is a hard drive, chip board. The light plugs onto the chip board same as a fan plugs onto a motherboard. I hope this helps you and it is under warranty,or at least they send you a new light if not.

Drive NOT being recognized by WinXP

Put your ear to the drive and verify if it is making any strange low level sounds. Check to make sure the usb connection wasnt affected. YOu wont need a driver as it appears to be hardware related. Either the enclosure or drive may be failing.
