[clug] Memory Stick Intrigue

[Jim Croft]

I have never been happy with what vendors do with memory sticks -
there is always some chunk or partition of various size that I can not
get at or reclaim, even with a reformat.

Could find a tool in Ubuntu that allows a thorough clean up and
'reclaim the byte'.  Maybe a clug guru knows about these things?
