Hello,

I PURCHASED A WD PASSPORT ULTRA 1TB HARD DISK
i)   i actually formatted the hard disk once, after that i connect FOR THE 1ST TIME to a pc,windows 7. though the task bar had the option of safe removal of the disk, it wasn’t detected /shown in the my computer option. i followed other steps given in the help page, but unsuccessful!

ii) i connected it to the Samsung LCD 42" series 5.but again it wasn’t detected or able to run any files in it! it shows NO DEVICE CONNECTED!
