Sorry if this is a foolish question, but I've been beating my head into this for a couple days now. Last time I tried making a backup, I got an error message that the volume was removed before ejecting. I actually still had it connected, so I'm not sure how that happened. At any rate, the volume still appears to be there and is taking up space on my HD. (Despite actually removing the disk and the volume not showing up on my desktop, in finder, or anywhere other than Whatsize.) I've tried repairing permissions, verifying and repairing the disk. I've even done this from a startup disc boot. All to no avail. I have attached the screen capture of what Whatsize shows to be the problem. When I try to delete the volume from Whatsize, it just says that item cannot be moved to the trash. Any help would be appreciated.
