Changing permissions on USB flash drive mounted on /dev/sda1 in a RedHat 9 box

[Andy Allen]

I can't change the permissions on a USB flash drive mounted on /dev/sda1
even when root - really frustrating as the drive is mounted in my user
area, but I have to log on as root every time I want to write to the
drive. Any suggestions as to how I can change permissions (chmod) or
owner (chown) for this device? - thanks,

Andy
