Hello,

calibre version 0.9.28 [64bit]

I use Windows 7 and I store my eBooks on an external server which is always accessible.

However when I try adding books or amending metadata for books I sometimes get:

ERROR: Failed(64, 'ReadFile', 'The specified network name is no longer available.')

Traceback (most recent call last):
File "site-packages\calibre\gui2\dialogs\metadata_bulk.py", line 125, in do_one_safe
File "site-packages\calibre\gui2\dialogs\metadata_bulk.py", line 177, in do_one
File "site-packages\calibre\library\database2.py", line 2526, in set_authors

File "site-packages\calibre\utils\filenames.py", line 326, in copy_path_to
error: (64, 'ReadFile', 'The specified network name is no longer available.')

At this point calibre 64 normally becomes 'stuck' and I have to close it down via Task Manager. Although sometimes when it looks like it is working again and I try to resave edits, I get:

ERROR: Unhandled exception

Any thoughts or suggestions as to how to deal with these issues?

Kind regards,
