Device won't sync

[Rellwood]

Not sure if this should be here, but I have a Kindle Paperwhite 3 (newest version) with the 5.12.2 update

Don't know what happened, but between plugins it stopped being read by Calibre

calibre, version 4.6.0
ERROR: Error: Error communicating with device

[Errno 22] invalid mode ('wbN') or filename: u'E:\\metadata.calibre'

Traceback (most recent call last):

IOError: [Errno 22] invalid mode ('wbN') or filename: u'E:\\metadata.calibre'


Any suggestions? I tried to configure the device, checked for problems on the memory, but Calibre reads the books to about 60% then I get the error.

UPDATE: I needed to update the device

That file IS on the device. (it is the previous found book list that also speeds up the later connect scan)
That, coupled with 'reads a book 60%' makes me think the filesystem or storage ON THE DEVICE, is damaged or failing.
Standard Q: Have you cold booted (used the restart item on the settings menu) the Kindle

I think I made the mistake of disconnecting it premeturely last time I was trying to sync it.

Long story short, I have two user accounts on the same computer.

When my Kindle was plugged in and syncing with the Calibre on my main user account, I switched users without ejecting or logging off.

After switching users, and starting Calibre (I have two user accounts so that I can keep working on another library while Calibre pluggs away dealing with some time-extensive job that otherwise would have me twiddling my thumbs)

When Calibre started up on the second user, I forgot that the Kindle was still plugged in and likely running on another library. I yanked out the usb cord and did a very bad disconnect.

When I returned back to the main library on my main user account (after logging off the second account). This was when I had problems.

What would happen is that Calibre would load the booklist from the Kindle, but at about 60% it would get that error I posted.

I updated the firmware, but still kept getting that error.

So...I figured on trying to load it up on that second account. When I attached the Kindle, I got that "scan and fix" option, so I did.

Once that was done, Calibre was able to get the booklist and send the metadata to the device. Up until that point the metadata file on the device was 0 bytes.

So, I suspect this was a very user-specific problem, and I learned my lesson

The books read fine on the device. It was the getting of the booklist that kept erroring out at 60%
