Hello,

I use Calibre now for more than 2 years, in order to manage books on my computer (Mac), and exporting them to many different devices (Sony PRS-600, Kindle 3, PocketBook Touch, Cybook Odyssey, and recently a Galaxy Note II.

Nearly all woks just fine.

Before asking my questions, I must explain how I mange my eBooks.

- First, I import massive quantities of books (ePubs) in one Time (between 200 to 500) each time.

- I make corrections in MetaDatas. I prefer correcting the titles, including the name of the series and the number. I add covers when absent, and so on. Since I still have a Kindle 3, I therefore add the mobi version to all the books, and convert the epub into mobi for the books not containing mobi in their packages.

Once it is done, I export all the recently imported books in a separate folder (ePub and mobi), and replace them in the original folder. THis way I'm sure having books with corrects metadatas. I prefer having copy of all my books in an other folder, for security reasons.

I select thereafter all the ePubs in order to transfer them into iTunes. I prefer not to use the communication between Calibre and iTunes, since transfers are very very long.

-----------------------------------------------------------------

So, now may questions :

1/ After importing the books into Calibre, not all the books have the same date in the Date column. I would have thought that it would be the date of the transfer, but for some reasons I ignore, some books have a different one. Happily, after importation, all the new books are at the top of the list, no matter of the sorting choice. So I select them all, and manually correct the date. I would like to understand why the Date is not the date of the importing day.

2/ Sometimes, The "save to disk" function failed. a few month ago, I thought it could be due to a hard drive problem, and as I had SMART issues with my disks (built in 3 RAID 0 ). I changed them. I non longer used RAID 0 system.

But this afternoon, after importing nearly 500 ebooks, correcting. I tried to save them on disk, and the operation could'nt proceed. The list of books not saved was pretty long (more than 50).

Instead of selecting all the books, I select only smaller amounts (50 each time) and save them into a particular folder which was emptied once saving process completed. ANd then, I only had little problems (3 or 4books). When a problem occured, I selected books ten by ten, an found those which cassed problems. Saving them one by one cause any problems. So if someone (Kovid ?

) could explain what's wrong, I would be very gratefull.

I don't know if the size of database is a matter of key importance, but I had more than 12 000 eBooks.
