I now get the error message:
K:\Pictures 2007\Mountains is not accessible
The request could not be performed because of an I/O error.
I know the name of the sub-folder is not relevant, but I just wanted to show that I can get in to the belly of teh K: drive with no errors.
All other pictures in the "Pictures 2007" folder open just fine, it is just this one folder.
The drive is a HP Personal Media Drive. I have tried reseating it, I have tried using it with a different usb connection and it always gives me the error message.
All comments and advice welcome.
