Windows 8 message when plugging Kobo Touch in

Hi,

Recently upgraded to Windows 8. Finally got around to reloading Calibre, Sigil and the Kobo Desktop. When I plug my Touch in (f/w 2.1.5) Windows 8 generates a message:

KoboReader (G: ) There's a problem with this drive. Scan the drive now and fix it.

The Touch has an 8GB SanDisk card in it as well as the standard storage.

I can use tools like Explorer to browse both drives without any problems, and Calibre can talk to the device without any problems, both loading and removing books with no issues.

So, I'm not really too concerned, but just interested if anyone else has seen this.

Apologies if this is already the topic of another post - I did search but couldn't find anything.

Any help greatly appreciated.

Cheers,

Pete
