[sovre]

I have been away for quite awhile and haven't used my reader, a 950 which I was using with Calibre. Because my reader takes about 10 minutes to start up and I do not know exactly where the problem lies, I am considering reformatting and starting afresh. However, I have a lot of ebooks and I have made a lot of notes and highlights over time and I do not know how to easily find all of the books containing highlights and annotations.
If I remember correctly, previously it was not very convenient to export using the Sony software. Is there any software or tool available now that would let me export all highlights and annotations in one fell swoop? If not, does anyone have any suggestions about the easiest way to locate all books which have annotations, so that I can begin the process manually? Thanks for your help.
