 Hi all,
 
 I've added some initial functionality to gnome-multi-writer yesterday
 to detect fake flash drives. If anyone has any USB storage drives that
 they know misreport their true capacity, or that they suspect might be
 counterfeit, I'd appreciate some testing of a new command line tool.
 
 See http://blogs.gnome.org/hughsie/2015/01/28/detecting-fake-flash/ for 
 details.
 
 If it works, I'll probably move the code down into udisks so that it
 can be used from gnome-disks as well, but I'm hesitant to do that
 until I've had more people test it. Thanks,
 
 Richard.
 


pIf you#8217;ve got access to gnome-multi-writer from git (either from 
jhbuild, or from a /my repo/a) then please could you try this:/p

my repo is actually what?

Do you still get this if you unmount the drive before running the
test? We should probably do that anyway I guess.

 Hmm, you're root -- do you have any SELinux messages? I'm basically
