What does this error message mean?

I am rearranging almost all of my ebooks and as I transfer some to the reader or update the collections/tags, I frequently get this message:

ERROR: Error: Error communicating with device

(13, 'Permission denied')

Traceback (most recent call last):
File "site-packages\calibre\gui2\device.py", line 68, in run
File "site-packages\calibre\gui2\device.py", line 333, in _upload_books
File "site-packages\calibre\devices\usbms\driver.py", line 186, in upload_books
File "site-packages\calibre\devices\usbms\cli.py", line 60, in put_file
IOError: [Errno 13] Permission denied

Then I unplug my Reader, wait for it to index, plug it back in, let Windows scan it, and continue. A few books will transfer okay, but then it will hang with this message again. Am I doing something wrong that causes me to keep getting this error? Thanks for any help.

The error message when sending metadata is different. Here is one of them:

I suspect it means that the cache/media.xml on the Sony has got corrupted. You could try removing it (or renaming it in case you want to examine it later) and then let the Sony rebuild it from scratch.

Thanks for the reply. I guess it is okay now. I formatted the memory and put everything back on. First pass, I did half the books and the collections wouldn't save, but the second half everything went fine. So I just had to go add the collections manually to half the books afterward, if that makes sense.
