My Passport Essential Not detecting with my HP netbook

Hi Folks i m having 500GB My passport essential which is not recognising with HP mini Netbook.

I tried with Y shaped USB cable and even with External 5 V USB Adapter to resolveissue of  power needed from USB ports still it dint worked out.

I am able to detect the CD drive unlocker but when i try to unlock it it gives me following message

" You must run the unlock application from the WD Smartware CD associated with the drive you want to unlock.Click exit, open and relocate the WD Smartware CD and then run unlock to run desired drive".

Mine is windows 7 starter pack with Intel atom processor running on 32bit OS.

Plz help

Hi there, my advice to you is to test the drive on another computer, perhaps a desktop computer and verify if the device works, this would be helpful to determine if the issue is in fact a power issue or is due to drive’s malfunction, please let me know the outcome. 

It works fine with desktop and laptop

Try installing the SES device driver
