External USB hard drive doesn't show up in My ComputerSolved/Closed

Question

Hello, 
My External USB Hard Drive doesn't show up in My Computer Win 7 64bit. 

I've just received my Western Element 2,5Tb today. When I first plugged it in, it worked normally. But due to my over-excitement, I copied too much files at the same time and it wasn't working anymore. I regretted doing this immediately. 

I have searched on the internet to find some solutions but all of them didn't work. I've checked the Computer Management, Disk Management, but nothing about my External HD showed up. In the notification area, my laptop still detected it and I can removed it properly [even though I can't use it at all]. 

I tried to connect to my USB and another Samsung 500Gb HDD. And it worked perfectly fine.

Then, I tried to connect my new HDD to my sister's lap [she is using Window Vista] and it worked perfectly fine too.

I don't know what to do anymore. Please help me.

System Configuration: Windows 7 / Chrome 23.0.1271.64

Hi AkemiHomura,

I checked your message and the error screen shots. Thank you for the detailed description of the problem. I see that you receive this error message in Disk Management console:

"The operation failed to complete because the Disk Management console view is not up-to-date.  Refresh the view by using the refresh task.  If the problem persists close the Disk Management console, then restart Disk Management or restart the computer."

Try using the below mentioned steps and see if the issue is fixed:

1. Click Start and type Diskpart in the search box.
2. Right-click diskpart in the search results > click Run as administrator.
3. Once diskpart loads type list volume, press enter.
4. You should notice that you will see your 2 TB Western Digital Hard Drive, it should not show a drive letter assigned to it.
5. Type select volume 1 (replace 1 with the volume number assigned to the Hard Drive in question).
6. Type assign letter Z (replace Z with the letter that you want to assign to it).

If it still doesn't work, please try the steps provided in the below mentioned link and check if the Hard Drive is detected in your computer:

Hi AkemiHomura,

Sometimes for a hard drive of such a large size a firmware is required for correct functionality. Try downloading the firmware from the manufacturer's website. If you need any help with firmware download, do reply with the correct Model Number of the Hard Drive.

Please do write back to us.
