A question which appeared on fedora-list recently was how to remove U#W

I've been trying to do that, and have a long thread going at
http://forum.eeeuser.com/viewforum.php?id=1
called "How to wipe thumbdrives??"
I've tried formatting under XP; under Gparted; under QTparted;
and going as root to a mounted one and using rm & rmdir. *Some* of my
thumbdrives now *seem* to be clear; and several do function as bootable
media with other distros.
Since those bootable drives are my chief current concern, I
haven't been nearly so meticulous about tracking what I've done with
which as I might; but i *think* I've picked up a joker in the deck.
Afaict (and I mean what my .sig says), a given Fedora app may or
may not always see this U3 foulness when looking at a given thumbdrive.
Often Fedora will tell me a drive is empty, but show a pie chart with
less than 100% available space -- and an open folder with ostensibly no
contents.
There is one post in that thread with a technique using dd; I
haven't tried it yet, but probably will.
I have a couple of those buggers as well. I think the dd you're
thinking of is something like:
dd if=/dev/zero of=/dev/sdb bs=1M count=2048
or something like that...the idea being to write zeros to the entire
drive, wiping out its partition table and all.
It does NOT work on the SanDisk Cruzers. I ran the dd three times on
each, writing all 4GB of data to them (took forever!). Fired up fdisk
and it reported a gparted-type partition table on them. The partition
table should have been wiped out via the dd.
I then ran gparted itself. It did NOT complain about a missing
partition table (it should have), but it did say there were no defined
partitions. Whoopee. Yeah, no partitions, but a gparted-style
partition table that can't be done away with. Sheesh.
<snip>
If I could find non SanDisk Cruzer thumbdrives here, I'd never
buy another.
I now buy nothing but PNY or Apacer thumbdrives. If I'm in doubt and
if the package says that something's preloaded, I treat them like
toxic waste.
