Errors with any change in the library
Hi I have a library that is being kept synchronized between two computers using dropbox in one of the computer everytime I open and do any change I get the following error
calibre, version 0.9.38 ERROR: Unhandled exception: <b>DatabaseException</b>:disk I/O error RemoteTraceback (most recent call last): File "site-packages\calibre\library\sqlite.py", line 272, in run OperationalError: disk I/O error Traceback (most recent call last): File "site-packages\calibre\gui2\dialogs\check_library.py", line 292, in accept File "site-packages\calibre\library\prefs.py", line 57, in __setitem__ File "site-packages\calibre\library\sqlite.py", line 315, in run DatabaseException: disk I/O error RemoteTraceback (most recent call last): File "site-packages\calibre\library\sqlite.py", line 272, in run OperationalError: disk I/O error Ho can I fix this? I am running Calibre 0.938 as Administrator and it seems access rights is not the issue. |

Immediately make sure you have a good backup of your calibre library! You may be close to loosing your books and/or metadata.
I can see three possible causes, someone more familiar with this error message may be able to narrow it down: 1. The Dropbox software is active and has the file metadata.db open, perhaps in order to sync it with the other computer. Make sure that you never use calibre on more than one computer at a time, and that Dropbox is allowed to fully sync with the cloud before you turn the computer off or try to start calibre on another computer. Calibre is NOT intended to be used with networked filesystems or Dropbox. You have plenty of room for mistakes that can cause data loss if you ignore this. 2. The filesystem on the disk is corrupt. Disk maintenance software in your operating system might be able to fix it. But maybe not without data loss. If calibre works ok from the other computer, make sure to copy that library over after the filesystem has been checked and fixed. 3. The disk itself has failed. Disk maintenance software might be able to temporarily partially fix this, as a reformat also might be. But most likely you will have to get a replacement disk soon.

In W7 being in an administrator group is not the same as being an administrator in XP.
In XP you always ran (admin) elevated. In W7 (Vista) you just have the right to elevate via UAC. In Unix, you would SU (sudo in Linux) to elevate a task right. The difference was SU lasted until terminated. |

I assume the OP is referring to the Run as administrator I've highlighted in the attachment Its an artefact of Windows Vista, Seven and Eight - and as far as I know its not needed for calibre, I have a recollection of KG posting that when it is used some calibre features wont work. See Teach Your Apps To Play Nicely With Windows User Account Control for a complete and very detailed explanation of the issues at hand (not for the faint hearted) BR Last edited by BetterRed; 07-11-2013 at 10:52 PM. |

Even though it is bad practice to routinely run a program like calibre as administrator, it should not be the cause of the error message described?
