James -- not sure why you're taking such a hostile tone out of the gate: feel free to be hostile if the answer I provide is somehow flippant or rude, but not before, eh?

Anyway, the 'freaking 1' is because you have more than one volume with the drive name. It's likely because your drive failed at some point and "fell off the bus". This caused the mount point to get converted to a folder with the same name as the drive.

To differentiate between the folder and the volume, the system adds a "1" to the end. To help you recognize this has happened, we show it to you.

To clear it up, use the "Go To Folder" command in Finder to open the /Volumes folder. Once there, you'll see the folder with the name "Data HD_Clone", and you'll also see the drive with the "1" after it. Delete the folder, then restart your Mac, and all should be well.
