Thanks for the info danny
I'll definitely give Lock hunter a go (or at least go have
a look at it now). I knew I'd be back here to edit within
minutes just like most of my pther posts, but I also wanted
to mention that in the drives device properties under the
policies tab I had already selected/ set this to quick removal.
There are a few threads on this forum about the same topic
and I should have done a search first - apologies.
Going to investigate your recommendation now- thanks again
Yet another edit!: I also happened to empty the recycle bin of the drive
just before reading your post danny.
