In my daily logwatch E-Mail I have just noticed the following:-

This possibly explains why the USB flash drive that was /dev/sdd failed to automount. It can be mounted without problems manually using a straightforward mount command.
Can anyone explain what I need to do to fix it? The flash drive has a FAT16 file system on it as is normal I think.
To add a little more information here is the sequence in syslog at the end of the sequence when the USB drive is plugged in:-

... and that's it, nothing more happens and the drive doesn't get automounted.
I guess the "Kernel Errors" message from logwatch is just telling me that it looked for EXT3, then EXT2 and didn't find them. It does the same for EXT4 but since the word 'error' isn't in syslog then logwatch doesn't report it.
Looking further I realise too that the 'errors' only happen if/when the USB drive is plugged in at system boot time.
So, they're not really errors and probably not related to my "why don't USB drives automount" problem.
The same USB drive works perfectly (i.e. automounts) in another xubuntu 11.10 system.
