Stupid question, is there a mechanical lock at the stick which accidentally closed the access to the stick. Otherwise I have no further clue what you could do. Unfortunately.
And, as a remark, as I am German and not a native English speaker some of your words are unknown for me. AWOL I don't know as well as kerflooey.
http://dict.leo.org which is a standard dictionary for me didn't have it in.
My apologies, I was using slang. "kerflooey" isn't a real word, it's more of an onomatopoeia -- a description of a sound, like BANG! or KA-BOOM! -- a minor explosion, in other words. Not a literal explosion, but a figurative one. AWOL is an acronym for Absent With-Out Leave, commonly used by the armed services to describe a missing service member.
As far as I can tell, none of the several different models of USB flash drives that have been tried on this particular computer have manual write-protect, and the same devices work just fine in other computers...
Well, I'll just leave this message out here in case someone else notices. If I can't figure it out, I'll just blow SAM away in favor of some other distro (probably Zenwalk). I liked having SAM, because the other two machines at the coffeehouse are running PCLinuxOS (the 1GHz machines referenced in my sig) and that lends a certain amount of consistency. But if flash drives are not going to work, I can't leave it out for public use...
