Hi,
I can write to just about the entire USB stick, with no errors:
atom:~# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 5.8G 1.5G 4.3G 26% /
tmpfs 2.0G 0 2.0G 0% /lib/init/rw
udev 10M 140K 9.9M 2% /dev
tmpfs 2.0G 0 2.0G 0% /dev/shm
atom:~# cd /
atom:/# ls
bin cdrom etc lib media nfs proc sbin srv tmp var

udev 10M 140K 9.9M 2% /dev
tmpfs 2.0G 0 2.0G 0% /dev/shm
atom:/# rm bigfile
However, after some amount of time, the errors occur below, is this USB
stick failing? Since it has no SMART, is there any other way to verify
the 'health' of a USB stick?
