Western Digital WD Elements 1 TB USB 2.0 Desktop External Hard Drive not getting detected

hi,

 My Western Digital WD Elements 1 TB USB 2.0 Desktop External Hard Drive WDBAAU0010HBK-NESN is not getting detected on my laptop, i have tried with two computers also, one with windows 7 and another with Windows Vista. And it not shown on both.I had purchased it on 31st July.

I am attaching the images I see on my Windows 7 . I can see only one"Disk Drive" under Device Manager. 

Device Manager

The Drive seems being constanly access and after soem time I got device driver error also. 

I have tried Re-Installing driver etc, but still i get the above error after sometime. I even tried the 

Data Lifeguard Diagnostic for Windows setup, but my Disk was not displayed on it.

Could anyone help me please.

:cry:
