USB port broken in 1TB seagate Freeagent external hard drive

Momentus is a SATA drive, so you can put it in any PC that has SATA bus to access the drive.
If you can borrow a SATA to USB dock, you can put it in the dock and plug the dock to USB port on a computer to get your data out the drive.
One example for the USB dock is EZ-dock and you can search on Internet for the picture.

I have SeaGate FreeAgent GoFlex 500GB external hard disk and it shows only 230GB. I formatted it many a time but still shows 230 Gb only..Please help me to fix the problem....

if it is dropped, there is a possiblity that the Hard drive lens may be damaged. Kindly consult your local pc provider for immediate repair..

If you are lucky and there is no scracthes on hdd disks, you can recover your files but not at home. Go to a recovery data office in your area and they can test your hdd and tell you what to do next. Do not try to recover data with any software because you can damage irrevesible your hdd and lose all your data.

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.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files. For example, see: https://services.seagate.com/index.aspx?lng=en-US for a "no data - no charge" guarantee.

The external storage device has several major components:
* USB cable
* external power-supply
* disk-drive inside the enclosure
* USB-to-disk-drive adapter inside the enclosure.
Try a different USB cable.
Try a different USB port on your computer.
Try a USB port on a different computer.
Take a multi-meter, and measure the output voltage/amperage of the power-supply,
and compare with the specifications on the label of the power-supply.
Open the enclosure, and remove the disk-drive, and attach it as a "slave" drive in a desktop computer, to see if bypassing the USB-to-disk-drive adapter bypasses the problem.
Look at the label on the disk-drive, for manufacturer, product-number, serial-number, and manufacture date. Access the manufacturer's web-site, and use "check warranty status" to see if the warranty still is valid. If so, the drive can be replaced, at minimal cost to you.
Buy a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.
Search online for a professional "data recovery service". For a significant fee, they can repair your disk-drive, just long-enough to copy your files to a new disk-drive. Seagate's web-site has an data-recovery offer: no charge if we cannot recover your files.

WHat you could do is test other usb ports on the system or you will have to remove the drive from the caddy and install it as a slave inside your pc and see if you can access the data,
If you can then you know its the caddy at fault

Here is another possibility that i found on another forum

"I was playing around in Device Manager, unplugging and replugging the hard drive. Finally I found that although it wasn't listed under Disk Drives or Removable Storage
, it was listed under USB controllers. It had a little x on the icon. Upon right clicking it I found that it had somehow become disabled on my computer. I'm not sure how that happened. I know I didn't do it."
or you can try this
Try this fix for missing usb ports by JohnWill

Create a file with NOTEPAD containing the following lines and save it as FIX.REG
-------------------------- Use text after this line --------------------------------
REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]

"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"
-------------------------- Use text before this line --------------------------------

Double click on FIX.REG and say yes to the Merge Into Registry question.

Unplug ALL USB devices.
Open Device Manager.
View, Show Hidden Devices.
Uninstall all devices under USB Controllers.
Uninstall all devices under Disk Drives that you know are not present.
Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.
If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

When this is done, reboot TWICE.

Reconnect the USB devices and see if they're recognized properly.

NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function.

If you cannot get the USB port fixed you can take the drive out of the inclosure and install it as a second drive in another computer that has SATA capability to get the data off of it. You can always put it back in if you can get the enclosure repaired.

You should be able to pop open the enclosure to retrieve the hard drive. You may need to take out a few screws.

Once you've done that, you can purchase another external USB enclosure to replace the broken one.

As you know,the Seagate sometimes has the firmware problems,so it seems that this firmware designed only valid in XP or Vista system,you may find the firmware update from the seagate official website
