Question about Seagate 320GB Portable External Drive Black 320 GB USB 20 Hard Drive

1 Answer

External 500gb hard drive not readable

Seagate external 500gb hard drive was suddenly not readable. It is visible in the device manager and at the computer management with a volume of 2.048 gb (instead of 500) and shows 0 data. The disk starts when you plug it and stops after a while. It seems to work mechanically but no logical connection.

Check the partition size in Disk Management (if running Win7 - download a free Partition Manager if not) and see if the system is seeing the partition correctly. Seagate has recovery software available on their website but you may just have to repartition and reformat.

3. The Computer Management Dialog box will appear.


4. Select the Disk Management Icon located in the right pane of the Computer Management Dialog box.

NOTE: Under volume you will NOT see the Seagate Drive.

6. Right Click on the Drive: Select Properties.

7. The "Seagate FreeAgent GoFlex USB Device Properties" will apear. Select the Driver tab.

8. Select the Uninstall Button.

If the drive has not yet beenproperly formatted for storage (which would seem to be the case), please follow the next steps.

1. Go to the Start Button and click.
2. In the little search wondow that appears directly above the button type "Computer Management" and a shorcut to that Administrative Tool will appear at the top of a list that pops up.
3. Click the Computer Management shortcut
4.In the new window, look in the left panel and go down to "Disk Management" and click it once.

My seagate 500gb free agent go not show any icon and it cannot show anydrive in computer.


if this is first use try this: (in Windows 7) right click my computer > manage > storage > disk management > see if there are any blank spaces under the "volume" tab > click on it > format > follow the steps and thats it.

if this isn't the case and the drive doesn't even turn on...this might sound dumb but make sure its connected to the electricity because the big hard drives need extra power other than the usb.

post back if you need more help.

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.
