The error message I get when connecting my Western Digital 1TB external HDD. It was running fine until about thirty minutes ago when it I couldn’t connect to it any more.
Since then I’ve rebooted my laptop, reinstalled the drivers for the HDD, attempted to use the Western Digital Lifeguard problem solver [can’t see the HDD] all to no avail.
[I ended up rebooting everything and it worked. *sigh*]
