Sadly, this was my experience as well. All of my cache folders were on the root directory of my Drobo. When I went searching for some older files last week, I discovered folder upon folder that had been emptied. I couldn't understand what had happened at first. It was only a Google search that led me here, otherwise I'd still be scratching (pulling my hair out) my head. Are your Premiere project files also gone? Mine are. There is no record on many projects that I ever did anything with them. I'm running an undelete program hoping to recover the files, but as I understand it the file names will be altered during the recovery process, and therefore the structure of the project will be completely, and irrevocably broken. I do think there is more here than Adobe is admitting to, but I'm thankful that they are at least speaking about this.
