This is where it gets a bit odd.
When I call up gparted I only see /dev/sdd (the harmless vfat
partition). I removed the vfat partition.
sudo gparted I get:
Unable to open /dev/scd1 read-write (Read-only file system). /dev/scd1
has been opened read-only.
Unable to open /dev/scd1 - unrecognised disk label.
The little blue light on the USB is flogging itself to death.
Interestingly, on my wife's laptop running MS Vista I had similar
results - it basically locked the thing up. Maybe I've just got crook
BTW Good point, but I'm more concerned about publicly-subsidised health
insurance going towards chiropracy and sports shoes than USB keys.
BTW2 ...tell me about it... My daughter in a specialised high-tech high
school takes in ISO standard document to her science teacher and he
can't read it !!! The govt spends millions on MS software and hardware
for schools, but isn't interested in air-conditioning, power points,
network cables or teacher training.
Ahhh, it's nice to have things to whinge about.
