Thanks for the reply
What script can I use to repair the Calibre Libray ?
I still do not understand why the cp -R command does not create the problem
with the Caves of steel.epub but syncing the Calibre Libray using both Unison and Rsync seem to result in the exact problem when running Calibre under Ubuntu
I agree that it is probably better to the update in Linux and then transfer to Windows but I need to use the larger screen on the Windows laptop to edit the ebooks and convert them to ePub in Sigil and Calibre
I have all the same tools in the Ubuntu netbook but the have a 10 inch screen on the Acer C7 so it is not as good for formatting as the 17 inch Windows laptop
That is why I just want to do a quick sync job via the USB Flash drive to the Ubuntu Netbook
TIA
Dave
