Verbatim external hard disk flashing but not starting

[giovantus]

Hello,
when I connect my verbatim external hard disk 320 GB to one of the USB ports of my PC, the blue light flashes forever but the drive doesn't start

So your Verbatim is not detected in your PC - is that what you mean.
Was it working fine before - Did anything change in your pc.
Did you try to connect this external HDD to some other pc.
