Hello everybody.

I think that I am having frequent errors in the books that Calibre (0.8.24) sends to the SD card of my T1. I started a previous thread in https://www.mobileread.com/forums/sho...d.php?t=155286 because I believed that the cause was more T1 related (and at first placed my suspicions in a particular metadata structure), but now I've come to think that it has more to do with the way Calibre sends data to the SD - or in anycase, with the way the T1 "builds up" its database from that data.

The thing is that, quite often, the thumbnails of many books located in the SD are "corrupted":

If you bring up their "info" page it is blank (i.e., no metadata such as title, author... appears).
When you "open" the book ANOTHER book opens. This only happens occassionally, but is not uncommon.
These "doomed books" (that are often quite readable) never make it to the "Continue reading" position, and are ignored in this respect, no matter how much you read it.

This can be fixed, somehow and in the short term, by deleting the SD card's "books.db" file, but I'm afraid that the next time that books are sent to the SD card they are in risk of having the same problems -at least in my experience.

Has anyone else experienced this? - Can anyone think of a "why"?
