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?
