Here's something to try but I'm not sure if it will help. There's a cache that MRJ keeps that might have this disk info in it. Quit LimeWire, IE, and other applications that use Java. Locate the MRJ Cache folder. On newer versions of MRJ it's at System Folder:Application Support. I think in older versions this folder is in Preferences. Trash the folder. You might need to restart. Try opening LimeWire again.
