I uploaded a single file to my ereader (Sony Prs-600) and after disconnecting there was a warning rectangle on the reader.

No Sony software in use (I have disabled its's autostart but double checked in task manager)

Turning off reader didn't work so I did a shutdown which did.
Turned it on and same rectangle.

Hit the reset button and my last book read was gone and all my collections. books on SD card were still there.

Plugged in reader to compter and calibre saw reader but not SD Card.
Sent book to main memory, no problem.

Unplugged ereader and book and collection for this book was there.
Exited calibre and started Sony software.
Sony software recognized SD Card and books on it but no collections

Exited Sony and restarted calibre and no SD card

Unplugged reader removed card, reinserted it and calibre recognized it.

I always check the jobs list (and remember doing so) before unplugging reader so unsent data should not have been the problem.

My collections are gone I know which isn't a bad thing as I was going to do some major changes to formats on many of the books so now I have no excuse to procrastinate.

Just curious as to what I might have done to cause this. I am pretty sure it is not calibre at fault, but me
