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

Hey everyone, just got a new Dynex USB 2.0 3.5" external enclosure and a 500 GB Seagate Barracuda 7200 RPM HDD and I set them both up, I've never had problems with an external HDD in the past but for some reason when I plus this one in the computer says that it's installing the standard drives and such to run it, then it says your hardware is setup or something like that. I go to "My Computer" and the HDD is no where in sight, and I have no clue how to fix this problem. It should be there right under My Computer right?

 If your running XP , go to control panal , Admin tools>Computer Management >Storage > Disk Management . Look for it there . If its there see if it says what file system . If none format it . If it isnt there then chack the jumper on the hard drive it self . It should be set to master or cable select .

USB port broke off. Can I connect to something else to get the data off the drive? I cracked open the case and it's a barracuda 7200 but I don't recognize the pin connections. Please help? Thank...

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

My seagate external hdd 500gb is not working and is not detected and regonised in any pc..

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.

The usb port is broken? how can i get to my info on the drive?

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.

Need a power cable

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.

Computer won't recognize my HDD in my external enclosure...

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.
