Hi Geoff,
Not a continual clicking noise or a continual whine - when plugged into the USB poit gives a off a low volume, two-tone buzz for a second or so followed a quiet spinning up, whirring noise for a second or so (which sounds like the drive starting up) followed by this buzz, whirr, buzz, whirr cycle ad infinitum.
Tried it on my destop at work and the same happens, and tried a different USB lead too - there is no other power supply or plug for the drive.
No idea about drivers loading up, all I know is that when I plug it in, it doesn't appear as a drive in "my computer" on my Dell laptop - my IT expertise stretches that far, but can follow instructions....
The mate at work is a comms engineer, who reckoned he could see the drive/data but that the control board was knackered, and that he didn't have the kit to repair it.
