[Inferno]

After the upgrade to Calibre 2.44 I found out three titles were not accessible.

I found this out while running winrar with the library shut down. These books were accessible at some point in the last few months as I had not had the problem prior to this backup and my last backup was a couple of months ago. Also, two of the titles had been saved from Calibre to my "library" directory that I use to populate my sd card for my tablet (I have a specific folder structure I prefer for my tablet as I like to read things in a particular order)

When I look up the books in Calibre the file formats are there. Looking in the calibre folder (just looking not changing anything) I see the three formats that were originally there... epub, mobi and lit.

Each format gave an error when clicked on to open in Calibre.

When I tried to add a "good" epub copy of the book it would not add to the record. The .lit copy worked fine.

I added the book from my "library" directory which had been saved with all metadata as a new record and it was fine.

I try to delete the book from Calibre using remove book and get an error
error(5, 'CreateFile', 'Access is denied')

The details show the following between the "==="

I am rather anal or OCD about my library lol and looking for a way to fix this without going into the file system.

Any suggestions?
