Making External HD recognizable

[IggyStooge]

Hello all,

I've got a 1.5TB HD in an Icybox that isnt recognized when connected via USB. I'd like to know how I can make it so it is recognized by any computer when connected via USB. Am I right thinking the USB alone is enough to power it?

Can anyone offer any advice please?

Thanks.

So once I've connected a power supply will it be recognized by windows? I can't try it at the moment, not got a power cable handy.
