Problem running Calibre under Windows 10

aceflor · 01-26-2016, 04:57 AM

I have been a very happy Calibre Portable user on a USb stick with a Surface pro for some time now. I have last week upgraded my Surface to Windows 10, Calibre seemed to work without problems until today. This is the message error I get :

Quote:

Then, if I try to search for an author, this is what I get :

I tried to upgrade calibre portable to 2.49 with the same results. Dito if I try Calibre x64 with my library on the stick.

What should I try next and is this happening because of Windows 10 or because my library somehow got corrupted ?

I'd be grateful for any suggestion.

Those errors both indicate invalid data is being fed into the database. The most likely cause of the problem is a misbehaving third party plugin. The first thing to do is disable all of them. Then if that does not solve the issues, attach the metadata.db file from your calibre library folder.

OK, thanks for the info. I'll disable all and add them one by one to see which one is the problem, and I'll get back to you.

Thanks again !

You can start Calibre from the commandline

Code:

calibre  --ignore-plugins

Although since this is a portable install, you will have to use the full path to calibre.exe, and set the necessary environment variables manually: http://manual.calibre-ebook.com/cust...ment-variables

I did disabled all plugins and the error message changed to "CorruptError: CorruptError: database disk image is malformed". I found this thread calibre corrupt error corrupt error database disk image is malformed, which corresponded exactly to my error message and followed the restoring database procedure, which worked almost perfectly.

My only problem left is that I have around 300 books (which is nothing compared to the amount in my library) which are in the library but without any format, altough if I use the "open the containing folder" option, sure enough, the epubs and/or azw3 are there.

What is the most efficient way to have those formats reappear in my library ? I did two library checks already but that did not solve the problem. Apart from that, the Library opens without any error and shows all my books, so that's good.

step 0 ) Make a backup of you library folder, 'just in case'

http://manual.calibre-ebook.com/faq....libre-is-blank Imagine the word 'Partially" being shown there.

If the rebuild fails to find all (or you have already tried this)
Alternately

Use Calibre to Move <<This keeps as much as possible of what you do have

the books (w/formats) it KNOWS about to a new Library folder using this procedure

step
0 ) Make a backup of you library folder, 'just in case'

1)Use the Library icon menu to Create a new Library (location) using the existing structure (tick)

2) in the original: Search: formats:true
2b) Select all (ctrl-A): right-click in the list:copy to Library: delete after copy

What now remains (in the OLD Library folder) is what Calibre forgot about due to DB damage

to recover this, you will now use the normal ADD (books).
3)The second item On the Add Books Icon pulldown menu (matches a normally Library layout). Point that to the Main (broken) Library folder (The one with all the Author folders)

If all that succeeds, you can just discard the backup of the damaged Library, and clean out the OLD Library remains

OK dok. Thanks a lot theducksfor taking the time to post a detailed howto ! I will give it a try tomorrow when I have the time and quietness.

"copy structure from the current library" is greyed out, I cannot tick it. I am using Calibre portable, is this the reason? It should not be...

Dun'o,

Been a long time since I used 'Portable' (I mostly run Windows X64 version)
It might be caused by Where you set the destination for the new Library??

kovidgoyal · 01-31-2016, 10:11 AM

It will be grayed out until you select "Create new library at the location" only if you have selected that will it be enabled.

Ah ok, that makes sense indeed. Well I have lost track of time today so I guess I will try that on Tuesday. Thanks to both for your precious help.
