KOBO H20 and Calibre

[intwtl]

Hi,

I have a Kobo Aura H20 Edition 2.

When I try to sync with Calibre it takes between 20 an d30 minutes to read what books are on the device.

Onboard storage is 5.2 GB of 6.7 available.

My old Sony reader had the same items on it and it took less than a minute to read what books are on the device.

Any suggestions are greatly appreciated.

Thanks

How many books are on the device? With 1.5GB used, I wouldn't expect that many. Less than 2000 books, probably less than 1000. And calibre should be able to fetch that number of books in less than a minute. It will be longer if the metadata.calibre file is missing or damaged, but still under 10 minutes. For the record, my Glo HD takes less than 2 minutes with nearly 5000 books. I have had reason to connect with the metadata.calibre, and that was still less than five minutes.

It will take longer if there are a lot of changes in the collections of series. I did change the collections management settings last night and the next connect on the Glo HD took about 8 minutes in the "Sending metadata to device" job. That was because it removed a lot of collections.

It is possible the issue is the database on the device. If it is corrupt, this can take longer. But, usually if it is bad enough to cause performance problems, it will raise an error when calibre is accessing it. If you have my Kobo Utilities plugin installed, you can check the database with it. That also has a compress option which will reorganise the database and can help performance.

The only other things I can think of is if something else is access the device at the same time. A virus/malware scanner would be the obvious thing. Or if the device was being mounted as a USB1 device instead of USB2. That would slow things down.

The plugin is called "Kobo Utilties". The simplest way to install it is to go into the calibre preferences, go to the Plugin section and click "Get new plugins" button and install it from the list presented.

That's a calibre standard warning.

As to 'who makes it?' ==>>

I did say "my" Kobo Utilities plugin. And as BR said, that is a standard warning and there are similar warning from other software when installing it. It is potentially true. But, the plugins available through the plugin installer are all posted to threads here on MR. The source is contained in them for anyone to examine. I think that if any of the plugins contained malware it would have been discovered.

As with installing any software, you need to decide if the risk is worth it.

thanks i would assume if anyone has had any issues they would have stated it?

A lot of us are happy users of the plugin. Davidfor is a stand-up guy who donates his time to the Kobo community. [Disclosure - of lack of it - I have never met him and receive no kickbacks of any kind.]
