MyPassport 320GB doesnt works

Hi everybody

I have a big problem

my passport 320 gb is not detected for any computer.

It’s not detected on Windows Manager Disk Tool (7 and XP) and Ubuntu.

When I plug to computer, led remains blinking but neither OS doent detect it

Is it dead?

is there a way to rescue my data?

I hope your comments

From Mexico

For troubleshooting avoid using USB extension cables or USB hubs, also check if the passport is recognized on the disk management window.
