I'll review this to see if there's another way to deal with it, but iTunes is very finicky about storage and writing to its copies of the books, as is calibre.

Yeh that all makes sense an I know its iTunes 'special' needs that are getting in the way here however at the moment I just drag a book from calibre into iTunes and this does not alter the original file stored in the calibre directory at all?

I just did it with an epub locked to read only. can it still write to a file even if its locked?

Maybe a better solution for allof this would be an add to iTunes option rather than an iPAD only option that creates a NEW copy of the epub in the Itunes directory AND adds it to iTunes then use itunes to sync the books, this would then also work once iBooks is added to iPhone in the summer.

this would also work if someone had add copy to library selected although they would have a duplicate unless you can set the driver to then delete the
