Unhandled exception: <b>DatabaseException</b>:disk I/O error

Hi

I am trying to remove a number of tags and also unnecessary additional formats (epub, lit etc)

When I try to update the metadata in calibre, I get the following error message:
ERROR: ERROR: Unhandled exception: <b>DatabaseException</b>:disk I/O error
RemoteTraceback (most recent call last):
File "calibre\library\sqlite.pyo", line 141, in run
OperationalError: disk I/O error

Traceback (most recent call last):
File "calibre\gui2\dialogs\metadata_bulk.pyo", line 120, in sync
File "calibre\library\database2.pyo", line 954, in remove_format

DatabaseException: disk I/O error
RemoteTraceback (most recent call last):

OperationalError: disk I/O error

My library is on a network drive but the drive is working fine and the library is complete, when I cancel the error message it completes the requested action but I can't undertake these actions for multiple files because of the error...

Do I need to delete the library file and recreate?

A disk I/O error means that some update t the database is failing. I would suggest moving the library off your network drive, doing these operations and then putting it back.
