External hard disk is not getting detected

[skbpalai]

Hi...................my seagate freeagent go 320gb external hard disk is not getting detected in my laptop. Even its light is not blinking.

I would check the power first. Does it have an external power supply, or does it receive power via USB?

This is an older thread, but may be of some help...
