First I get a RO-Kindle.

I do
sudo fsck.vfat -a /dev/sdc1

dosfsck 3.0.9, 31 Jan 2010, FAT32, LFN
/metadata.calibre
Contains a free cluster (358912). Assuming EOF.
/metadata.calibre
File size is 107532 bytes, cluster chain length is 16384 bytes.
Truncating file to 16384 bytes.
Unable to create unique name

Then I upload a book and get the error-msg.
After that I get again a RO-Kindle and the book on my Kindle.

Here is the calibre Debug log
