This sounds like the fix for your problem
Thanks for the link!

mount via Terminal and Ubuntu's Disk Utility both show that the node is /dev/sde
sudo fsck.vfat -y /dev/sde appeared to run ok
calibre jobs list Get the device information status = Finished
however calibre jobs list Get list of books on device status = Error
ie the original Error communicating with device
so, sudo fsck.vfat -y /dev/sde didn't fix it, in this instance ...

Fine, except in my case I'm not using a SD card, rather everything's stored in internal memory. Nevertheless, formatting it solved the problem originally, so it would appear to be the best way forward.

Addendum
Problem now fixed, without formatting the reader's internal memory:

Connected reader to PC via USB
Ubuntu > System > Administration > Disk Utility
Selected Sony PRS-650 from the list of Peripheral Devices
(ie Sony PRS-650, Sony PRS-650 MS, Sony PRS-650 SD and Sony PRS-650 Launcher)
Unmounted the volume (which was mounted at /media/READER)
Clicked on Check File System
Re-mounted the volume
Started calibre, which got both the device information and list of books without any errors.

This might be useful to anyone else using Ubuntu.

I don't know why checking the file system via Terminal didn't seem to fix the problem, whereas Ubuntu's inbuilt version did, but certainly I'm glad that I didn't have to format the internal memory, again!

Thanks for everyone's help :~)
