is mounted as read-only and all of my background sync cron jobs have been failing.

So I need to fix this without rebooting the server. How can I get this drive r/w?

Have you tried "mount -o remount,rw <mountpoint>"?

# mount -o remount,rw /media/HD103SI/ mount: cannot remount block device /dev/sdc1 read-write, is write-protected

The unanswered question here is why did it go read only, and does this condition still exist?

The burning question of the day......

Should I 'just' unplug it, power cycle it and reconnect it?
