One of my USB-sticks suddenly 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 can 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
