Calibre 0.9.24 [64-bit] Permission Denied Error

[edwdecarlo]

Setup::

Laptop: Dell Precission M6700
OS: Win 7 Pro 64-bit
Hard drive (Library storage): Western Digital External USB

Issue::

I upgraded to v0.9.24 [64-bit] today. Now, when I change the title or author I receive a Permission denied error 'Could not change the on disk location of this book. Is it open in another program?'

Details:

calibre, version 0.9.24
ERROR: Permission denied: Could not change the on disk location of this book. Is it open in another program?

Locked file: e:\archive\ebooks\templibrary\tempworking\dan abnett\doctor who - new series adventures - 030 (27970)\cover.jpg

Traceback (most recent call last):

I rebooted my laptop to clear any possible locks. The only application I have accessing my library directory is Calibre.

This does not happen every time, only about half the time and eventually my title or author change will be accepted. It has been several months since I have done any title/author changes (or changes which would affect the stored dirs/files), so this may have been occurring before 0.9.24.

Solution::

Remove Library from Windows Indexing. Delete and rebuild index.

Doing this resolved the issue in my setup. If this does not resolve your issue, please see below for additional suggestions from other members of the Calibre community.

Thanks to all for your help in figuring out this issue.

Are you sure you don't have the book open in the book viewer? While it is a part of Calibre, it is also runs standalone and allows multiple books to be open at the same time which is why it is not 'modal'.

Some sort of disk cache/cloud may be locking the file.

Not to mention an antivirus program, or having your library on a network disk.

Is it possible you may have been editing the cover ?

Thank you everyone for your input/help.

I do have an external hard drive which holds my library, but it is not a network drive, it is connected to my laptop via USB and is not shared. I was not viewing the book, or editing the cover.

I have had my library on the external drive for quite a bit of time and had not had this issue in the past. The issue is intermittent, and eventually after 2 or 3 repetitive tries it is able to accept my change (move/rename the book files) without me having to exit Calibre or reboot.

I did receive a driver upgrade for USB 3.0 recently, so perhaps that is interfering with the Microsoft file locking detection at times.

I am also removing my Calibre dirs from the Win 7 file Indexing to see if this is the issue. Perhaps some Windows update has affected the Indexing and locking on external drives (in the past Windows has assumed C and D to be physical drives and E or higher to be network drives which require a higher level of security/monitoring, and my external drive maps to E). I'll post the results once Windows finished the file Index rebuild.

Thanks again.

Also Exclude your Library folder from Real time Antivirus scans.

Windows users can lock in a drive letter (Mine is L: ) Using the Disk Manage (run: diskmgmt.msc) so it always keeps the same letter (suggest using letters in the range that will never get used with a New disk device)

@theducks - Thanks for the info. I have been looking for where this is controlled since I switched over to Win 7 from XP. I'll give both of your ideas a try.
