Dear CB

You haven't mentioned much about your system so I can only make a wild guess at your problem.

I will base my guess on

a) You probably run Win XP

b) Have a fairly modern PC

C) You wrote the following:
Most PCs "D" drives are either CD or DVD players/writers, it could be that you have mistakenly set your external as a "D" drive when it should be "F" or beyond.

Therefore, to be safe, check your drives letters and make sure that your external has a different letter to anything else on your system, this will also include digital camera memory drives (these have drive letters too).

This may sort out your "directory/drive" problem.

PS. I run a couple of externals as well, which I have lettered "I" and "N".
