Ha! I've found a quick way of using it.
I wanted to move 2 files from one folder to another. This took 55 mins to achieve using the supplied software - basically cut & paste. So for the next 2 files I wanted to move, this is what I did :-
I powered down the Buffalo and my pc.
I removed the HDD from the Buffalo.
I pulled the pc box out from under my desk.
I switched the power off at the back.
I removed the side panel.
I earthed myself.
I removed a spare HDD.
I installed the Buffalo HDD.
I powered up the pc.
I copied and pasted the 2 files in 15 secs.
I powered down the pc.
I removed the Buffalo HDD and replaced it in its caddy.
I replaced the original HDD in the pc.
Whilst the pc was pulled out from under the desk I vacuumed behind.
I pushed the pc back under the desk.
I powered up the pc and the Buffalo.
I waited 10 mins whilst it woke up and hey presto!
The 2 files had been moved.
This took 25 minutes, so I gained 25 mins of free time.
I'm so happy.
