One of my local cybercafe's desktops doesn't list my USB drive among the usual C:-etc. letters anymore, from Windows Explorer (it should be F:, after the two CD-drive letters), but I can reach it okay from [Open File] in Firefox.
I can't right-click-and-Explore either - any attempt to reach my USB via Windows Explorer doesn't work at all.
It was fine this morning. How the hell did this happen?
