Yes "blank a drive" aka "formatting" it.
With the same file system it previously had. (fat32).
as i understand it, formatting a drive doesn't necessarily overwrite
the whole disk & blanking (erasing) it is too expensive for a default
formatting. and Alan was perhaps too subtle- flash does funny things
when you write to it.
Doesn´t need to be a "full format", a "quick format" would do.

notice that in both cases, files are 'removed from the volume',
not erased.
So, I maintain my original comment... I think it should be possible
from the Gnome GUI to right click and select an option to "format" the
drive (who partitions a thumb drive?? 99.9999% are used in a
single-partition mode)
this would be handy- but would probably be limited to vfat...
Hey, look here
http://library.gnome.org/users/gnome-help/stable/disk-format.html.en
"If you have a removable disk like a USB memory stick or an external
hard disk, you may wish to completely remove all of the files you have
on there. You can do this by formatting the disk - this deletes all of
the files on the disk and leaves it empty."
delete- not erase. and certainly does not leave it empty-
an empty drive has no format.
Wow, plain English. No misconceptions about what formatting means. :)
So let me rephrase my original post: on removable drives, shouldn´t
there be a "Format" option (or "wipe" if you wish) that invokes
´disk
utility´ with the right params to beggin formatting it?.
with a prompt for the root password.
