Seagate 2tb expansion drive not working

[Antho0123]

Hi all, my Seagate 2tb expansion drive is not showing in My Computer or in Disk Management. However it makes the connection and disconnect sound. This is the second night I've tried to resolve the problem by Googling and looking on various forums....I'm a broken man!

Can we get a bit more info from you?
-What kind of computer do you have? (Laptop or desktop? Prebuilt or did you build it yourself? If you have the specs, it'd be helpful to know those)
-What OS are you using? (Windows XP, 7, 8, etc)
-Just to confirm, this is a USB external HDD, right?
I would check the Device Manager under Disk Drives to see if your computer is recognizing that there's an external hard drive, or if there's an unknown device that might be your expansion drive.

Hi Earthen,

I've I'm a Packard Bell EasyNote - specs - 4GB DDR3, Intel Core i3-330M processor.
On Windows 7.
It's a USB drive but powered by it's own plug in source.

The Disk management only doesn't show the external drive for some reason.

I've read it could be a power fault but it seems to be humming away. Could it be something put on the drive that has corrupted it?

I assumed this was a brand new drive that you were trying to install for the first time. Is that the case? If so, then it certainly could be a faulty drive, but I suspect it's a driver issue. If this is an old drive that worked before, though, we're looking at an entirely different set of steps to take. Let me know, and I'll see if I can help you out.

have twice had this problem with the 2tb drive. green power light is intermittent and drive not recognised. 1st time returned under warrenty and got a new drive but lost all data. 2nd time same drive, removed the hard disk from the unit and installed in my desk-top as another drive. all data recovered. the fault lies in the power connecter on the Seagate drive caddy. on the up-side I now have 2tb drive in my desk-top. don't trust the recent Seagate expansion drives, but my old 1.5tb drive is ok for now
