out of the blue one of my usb-sticks stopped working.

I get the following errors in Linux:

sudo dd if=/dev/zero of=/dev/sdc bs=512 count=1 dd: writing `/dev/sdc': Input/output error

sudo mkdosfs -F 32 -I /dev/sdc mkdosfs 3.0.9 (31 Jan 2010) mkdosfs: failed whilst writing reserved sector

I have tried to re-format it using windows but that does not work either...

The stick does not have any visible way to make it write-protected...

What could I try?

Is this drive worth more than the injection-molded plastic it's made of? –  digitxp Aug 15 '11 at 23:55
Try gparted - its a much better way to do this, without the possibility of typing sudo dd ... of=/dev/sda and killing your root (and yes, I've done that). –  new123456 Aug 16 '11 at 0:43
