After calibre update having some issues with errors

[chaley]

Calibre continues to think that either:
1) there is a file metadata.db in your library folder that calibre does not have permissions to open, or
2) that calibre cannot create the file.

From the trace, I would guess #2, but it could be #1.

At this point I have no idea what state your machine is in, so I can't give you any sure-fire directions. What I would do is:

1. Delete the calibre preferences folder. This will force calibre to ask where to put the library. The location of your preferences folder will depend on your OS. On Win7 it is in C:\Users\yourname\AppData\Roaming\calibre. I no longer remember where XP puts them, but it will be something like
C:\documents and settings\yourname\Application Data\Roaming\calibre.

A calibre preferences folder will contain, amongst other things, the files global.py, gui.py, and tweaks.py. If the folder doesn't contain those files, then don't delete it. Post back here with the path of the folder.

2. Start calibre. It will start the welcome wizard. Tell calibre to make a new library in a non-existent folder. Do not reuse any folder. At this point you should have a running version of calibre with an empty library.

3. If you think you have a library somewhere, click on the library toolbar button, enter the library's path into the box, select 'Use an existing library', and press OK. If the library is really there and valid, calibre will switch to it.

My path for the preferred library was C:\Users\yourname\AppData\Roaming\calibre. I was able to delete that file and restart calibre. Went thru all the start up then got the same error message about the data file being corrupt. Here's the details from the error

This is what i got when i used a new folder. The error said
"disk I/O error remote traceback (most recent call last):

line 215, in run

Calibre is telling us that the disc where you are attempting to store the library is badly broken. Are you trying to put the library on a NAS or an external drive? On a drive with no space?

[mted558]

no it's going on my C drive.

[chaley]

I am at a loss. What is clear is that Windows is refusing to let calibre create a database, saying that the disk cannot be written. My guess is that your C: drive is corrupted, but that is only a guess. It could be permissions or policies, neither of which can be debugged remotely.

At this point I bow out. Perhaps someone else will have better ideas about what to do.

[mted558]

thanks so much for all your help. Hopefully someone will have some other ideas

You could try and run a disk check.
Also, and this is possibly very stupid, but I just thought of it: You do actually have write privileges in the folder you're creating the empty folder in that your Calibre library should reside in?

I agree.
Disk I/O error is bad hardware (drive,cable,PSU) or damaged file system
If you have a UBUNTU Live CD handy, boot that and use "disk Utility" to view your drives "S.M.A.R.T. status (the hardware, not the file system)
Using the Live CD does not require making any changes to your system (don't click Install, Nor change any drive partition while peeking)

[mted558]

Yes I do have privileges unless it's not automatic, meaning every time I create a folder do I have to give myself privileges? I'm going to run a disc check now and see what happens.

[mted558]

update...
i did a disc check, deleted all the old files and reinstalled calibre and now everything works fine so it must have been a corrupted file. So far, everything is working without a problem. Thanks for all the help.
