I want to create a USB stick with a tool to scan for viruses. I installed the software and after that I set:
hdparm -r1 /dev/sdc1
When I check the USB stick I get this:
hdparm -r /dev/sdc1 /dev/sdc1: readonly = 1 (on)
When I unplug the USB stick and plug it back in I get this:
hdparm -r /dev/sdc1 /dev/sdc1: readonly = 0 (off)
The write protection seems not to be not working.
How can I make the setting persistent?
