So I connected the reader to the PC (mac OSX 10.5.8) and launched Calibre. Calibre worked hard for 2 or 3 minutes to get the list of books from the reader and finally crashed, I repeated this 3 or 4 times and Calibre crashed hopelessly. I have all the books in the SD card, but calibre is not able to read it, even with a healthy .xml file. Maybe the calibre metadata gets in conflict with the xml file... I also noted that calibre creates 2 metadata files one on the main memory and one on the SD card... Is this normal? I will start from scratch, initialize the SD card, and do a completely new upload to the clean SD card.

I will get back as soon as the problem reappears... It seems to me that after doing the first upload of books to the reader, the xml file gets corrupted...

thanks
There is an xml file on the card as well, called cache.xml.

Yes, it is normal that calibre creates to metadata.cache files.

Calibre crashing is not normal.

As I said, I doubt that calibre is systemically corrupting the xml file, unless your 650 is different from the others that work just fine. That said, I can't help you any further, because I don't own a 650 and I can't touch yours to see if your memory card is bad or your 650 is bad.

NB: a faulty memory card is well within the realm of possibility. Try putting the books into the Sony's main memory. It will use the same XML format as the card. If it works there, then a giant finger of doom is pointing at your SD card.

Good luck.
