Hi there, I have a Seagate 1TB External Hard drive not being detected after i switched the laptop off while downlading a software file on the hard drive, that i couldn't stop & after the laptop came back up it couldn't detect the HD. Tha power comes on on the HD & the disk spins as it has an adapter & the USB connected to the laptop. Sometimes the light stayed on & lately it only flickers. Tried it on another PC doesn't get detected. Plz some help would b great. Thanks.
