An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

Hello there,

What type of OS are you running ( Windows # )

What type of motherboard

Here is what i would do to start off with,


STEP ONE - Check all connections

1. Unplug the USB >Check the ends of the USB >Reconnect the USB >If you are connecting an Iomega Desktop Hard Drive, check the power supply connections to the drive and power outlet to ensure that they are secure.
   
2. Restart the computer.
   
3. Double click the Computer or My Computer to see if the Iomega Hard Drive is detected.
   
   If the Iomega Hard Drive is detected, you can now use the drive.
   
   If the Iomega Hard Drive is not detected, please try another USB cable and/or power supply (if available). If the Iomega Hard Drive is still not detected, continue with the next step.
