3.5" Dynex USB 2.0 External Enclosure + Seagate Barracuda 7200 RPM 500 GB HDD problem with computer recognizing the HDD and the enclosure

Yes just fixed mine. Went to radio shack bought a gigaware sata 3.5 external enclosure.
Took the harddrive out of old enclosure. pryed off external alluminum case to expose a panel that sticks out to the side where the broken usb plug went. Wiggled that off then placed in new enclosure fits good. secured with old screws. plugged it in and it works great. The new usb plug is much sturdier. The external case cost me about $40.00 and some change but Im glad i retreaved my data. I will never buy another seagate. Hope this helps...Alan

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.

Open the enclosure.
Separate the disk-drive from the USB-to-disk-drive adapter.
Connect the disk-drive as a 'slave' disk-drive in some computer,
to access the files.
Or, for about $30, buy a new 'empty' enclosure, and transplant your disk-drie into that enclosure.

try replacing all the leads that attach to your hard drive including electrical extensions + IDE,SATA and the ones that attach from your motherboard to hard drive
have secure connections and are not faulty or just replace them they are probably old and faulty ?
good luck

A user on the Seagate forums indicates that his uses a 12V 2A DC power supply. I would suggest, however, that you remove the hard drive from that enclosure and place the drive either inside your PC or inside another enclosure.

If all else fails, contact Seagate: 1-800-SEAGATE

Let me know if this helps!

An external USB drive consists of tow parts:

a hard drive (usually a standard IDE or SATA drive), and

an enclosure

The enclosure is the box containing the drive. It also includes an interface to convert the data from the IDE or SATA interface on the drive to a USB (2) signal. Some enclosures include and internal power supply. The Freeagent has the power supply externally.

Hope that's what you mean.

i have the same problem, would a new enclosure work?

Hi, Initially, allow Windows to install automatically drivers or needed configuration, then perhaps you need to reboot. Thereafter check if it can be seen in My Computer, otherwise, pls post back for any messages or errors. Good luck and kind regards.
