Calibre corrupts my ebooks

[babesz]

Hi,

I've been wanting to use Calibre for a while and now I've finally given a shot to it. I copied all my files from my PocketBook library to my computer, and started adding them to Calibre, did some tweeks to the books (like downloading a cover page, converting to different formats), but to my biggest surprise, when I disconnected my ebook reader from the laptop, I could not open the ebooks in the reader (Pocketbook would detect them, but would not open them).

This happened irrespectively whether I tweeked with the file format or not, edited the cover page or not. Basically, even if I did no conversion to the original file, as I sent it to my Pocketbook via Calibre, the book could not be opened anymore. In contrast, when I just copied the EPUB, or whatever file, from my Windows library to Pocketbook, I could open them as usual.

I really don't know what I'm doing wrong. My guess is either that Calibre doesn't support Pocketbooks, or it has some problem with pirate books (which I *sometimes* happen to use ), or I'm just really lame to understand how Calibre works.

Can you please help me how I could find out what the problem is?

Thank you in advance very much!

calibre works fine with PocketBooks as far as I know, although it has no special code for poketbooks, beyond the device drivers. First check that files copied to the device can be opened in the calibre viewer to ensure they are not damaged.
