Hi bmag

Thanks for reply.

When the problem first occurred I re-authorised ADE, but no joy. I then uninstalled ADE and deleted any residual files and directories, and then reinstalled ADE and re-authorised the Kobo. Still no joy. I currently do not have ADE installed at all. The ePub books that I want to reinstate on the Kobo are not "protected" by DRM so until the problem is fixed I would prefer not to "complicate" matters by introducing another factor.

I have had some partial success in resolving the recognition of the SDHC card. There were some ePub books on the card which had been transferred there with Calibre, and were readable on the Kobo under the 1.4.* firmware. When these were deleted (using File Explorer) and the card inserted in the Kobo it would boot up with the empty card. The moment that I transferred an ePub file (using Calibre) the Kobo would no longer recognise the presence of the card.

It is beginning to look like the problems are related to the ePub files themselves, and I would appreciate any ideas as to how the ePub files could be causing these problems. Note that none of the Epub books were DRM protected. The question is what changed when I upgraded the Kobo 1.8.3? Does the Kobo apply some form of DRM to the books, or is it loking for some addional ïdentifier? There has never been an error message on the Kobo.

Any help would be much appreciated.
