Hi,

it seems that KSM is the culprit.

What I did:

- Factory reset
- Starting with small batches of around 100 ebooks and going on to larger ones with 500 ebooks I copied 1500 books without problems
- Installed KSM again
- Copied 100 books to the reader with calibre
- Database was ok after copying
- Unplugged and waited for the reader to finish processing the books
- Plugged it in again and lo and behold, the database was corrupted
- Disabled KSM
- Copied back the last version of the database
- Unplugged the reader, plugged it in again and checked the database (everything ok)
- Copied another 500 books
- Database is still ok

I'm not sure what KSM does (or the file monitor) that corrupts the database, but it definitely does something.

@tshering: How can I determine what happens in more detail? I'm willing to experiment to some extent, because I would very much like to have the ability to choose koreader (for PDF reflow) and Coolreader (simply because I can) for my reading experience :-)

Cheers, Joe
PS: Comparing koreader, CoolReader and the Kobo-own reader implementation, which one renders books the best?
PPS: I really like the ability to sort books in collections. Is this possible with either CoolReader or koreader?
PPPS: I should probably start an own thread for this discussion...
