Hi David

In the meantime I checked the calibre.metadata file. The size is 395MB.

Ok, I have to precise that I use the ereader only to read... no games, no internet, no wifi. And of course, with this type of library, I take specially care of each single book - not corrupted, size, polish, classification, shelves etc - to avoid any corruption of the DB. On top, I have an full image to be able to restore the device if something breaks.

Thanks for the tip to turn off the "Read metadata from files on the device" feature. I'll try it out the next time I connect the device and have a look if it runs faster. (by the way, when I connected this evening, took exaclty 8mn45sec to synchronise with Calibre, which is already a good score for 53000 books on the device).

Regarding the FW version. In fact, I tried out the FW 3.19 but faced the issue that the device returned a "fatal error" around 40000 books. The only way out was a factory reset... and to start again. I have several GloHDs (not all mine, but I take care of) all set up in the same way, which excluded a HW issue on one single device. Therefore, I came to the conclusion, that the FW may be somehow limited.

So this was a kind of no-go for me to upgrade.

Now, as I like to explore the limits of my devices

, I'm making tests with the Clara... and the Clara is not compatible with the 3.18... so I must use a 4.x version.

which I find "sexy". Just curious to see if I'll be able to cross the 40000, or if it's limited also.
