I bought my HDD on 2009. It´s “WD Passport Elite External 500GB USB 2.0” Serial Number [Deleted].
I never had a issue with my HDD but on last week I decide to format and I download the software named Windows Data Lifeguard Diagnostics ( http://wdc-es.custhelp.com/app/answers/detail/search/1/a_id/6130/c/130/p/228,195,254#external)..)
I used the option FULL ERASE. The process was end correct.
But when I connect the HDD in any computer (Windows7 or Mac) the Disk not appear in “My PC” .
The HDD is connect (On Devices and Printers) but I can open or load or save any file on HDD.
Maybe I need a driver for my HHD, I try to find any answer on WD portal and I find this link( http://support.wdc.com/product/download.asp?modelno=WDMLC5000CN&x=11&y=13 )
but I have the same result.
COULD YOU HELP ME?
