Are you sure there isn't some bug in Calibre? I can easily move files inbetween the SD card and internal memory using windows explorer, but Calibre always throws up the same error everyone else is getting (this is on a Kobo Wifi). I think this warrants a bit more investigation than just telling everyone to return their readers

Well, I've read a bit more. A couple of things to try;
-ensuring that the Kobo is unplugged from computer using the 'safely remove' feature -making sure the folder directory that opens when kobo is plugged into the computer is closed when making changes Those 2 ^^ things helped some people when these errors started happening last year. Also, Kobo just released a new firmware version [yesterday I believe], and very recently Calibre had a new release as well. I've downloaded both of these, and I tried out my Kobo today, with new purchase and changing some of my metadata, and all seemed to work, so far *knocks on wood*. |

Well, I was trying to be helpful, but now I'm having troubles again myself. After I posted yesterday, I deleted some books from my KT to re-add them with new Calibre code to keep them in series order. This is the error I get now when I try to change more than 1 thing at a time:
unable to open database file Traceback (most recent call last): File "site-packages\calibre\gui2\device.py", line 82, in run File "site-packages\calibre\gui2\device.py", line 436, in _delete_books File "site-packages\calibre\devices\kobo\driver.py", line 434, in delete_books File "site-packages\calibre\devices\kobo\driver.py", line 349, in delete_via_sql OperationalError: unable to open database file I figured the easiest way to change it is to reset my KT, AGAIN, and rebuild my library from scratch, AGAIN. I'm just waiting to decide if I'm updating my Kobo to the newest firmware before I start again. So good luck. Apologies for trying to be helpful when I'm such a newbie myself, I just know how frustrating it is.. |

glad to see it isnt just myself having these errors; kinda
anyone else have any ideas it seems like the problem is the way calibre communicates with the kobo itself, could it be a metadata issue? one thing that i did was to not have calibre create sub directories of the author, just the have the books to see if that made a difference.... |

Blue2,
I had a look at the code to see what is happening where you are seeing the errors. Calibre can't open the database on the Kobo Touch to remove the entries for the books you are deleting. But, it should have already opened the database when you connected the device. Which means that you should have gotten an error earlier. As an experiment, could you try to get the annotations for a book? If you don't have annotations on any book, try it for a book you have started reading. This will add to the comments, how far through the book you are. The main thing this will tell us is if Calibre can read the database at all. David |

After this happens, what happens if you try to look at the ereader using explorer? Also, what happens if you don't use Calibre at all and just drag the ebook files to the ereader? To me what appears to be happening is that after the initial accessing of the ereader from Calibre, it is being disconnected. Hence, any further access is failing by Calibre. The question is of course why this is happening. There are suggestions earlier in the thread to try. Other things to try are a different USB port, cable or a different computer. The object of all this is to determine if it is the ereader, the PC, Windows or something else. It is very unlikely that it is Calibre as it is just finding an underlying problem. |

I did 'fetch annotations', I selected 1 book I was reading and the comments do show the last date I read it and % done. So there is some type of communication between Calibre and KT. [can I delete the annotations now? I would prefer to have the book summary show only, how do I do that?] Once KT connects, I close that folder that opens, [I had read somewhere that leaving it open causes errors, ?!] I thank you so much for your time and help. I will keep trying different things, next time a different USB slot, dragging book directly to Kobo folder, etc. It's just frustrating because I've never had problems with earlier Kobo [1st gen] and not on my KT either since upgrade in the past couple of months. If I find a sure-fire way to work around it, I will post. Problem is I seem to go in spurts where I just read for a long time, and don't bother with making any changes to my library, and then I go for a couple of weeks on buying/or free download spree and change it quite often. |

You delete the annotations by opening the metadata editor and deleting them from the comments. Quote:

An earlier suggestion was to do a checkdisk/scandisk on the KT to look for filesystem errors. Have you done this? |

So at this point I am thinking it's my computer. It's just all too strange, right? I've been shopping for a new one anyways, scouting every week for that PC deal of a lifetime. Better start dropping a few more pennies in the savings jar! Thank you again so much for your help. If by chance I do get something figured out and it's not my computer, I will try to remember to come back and post about it. Thanks again! |

just thought of something; could these read/write errors be caused by anti-virus scanning software? as its scanning the files transferred and not allowing calibre to access them??
