Hi,

I can write to just about the entire USB stick, with no errors:

atom:~# df -h

/dev/sda2             5.8G  1.5G  4.3G  26% /

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?
