PRS-505 doesn't recognise memory stick.
My PRS-505 has stopped recognising my memory stick.
It used to work fine, but the other day I 'lost' all my books and collections.
The memory stick itself seems to be OK, as I can plug it into my PC and browse it and the books are there.
It also seems to be electrically connected to the Reader because when I connect the reader to my laptop both the OS and Calibre are able to see the memory stick.
When I disconnect the reader from my laptop it scanns for new books and only shows books in main memory.
I have tried deleting media.xml with no effect.
Is this a known problem? Any solutions?
