I have a USB thumb drive (128M) that when it is installed before boot it is not seen . And when it is installed after boot I can't get it mounted . I get an error "/dev/sdc1 is not a valid block device" . I have aded it to my "fstab" file and added a new dir in /mnt/usb . It should be /dev/sdc because when I run fdisk -l my hard drives come up as sda and sdb . If I remove the drive and reinsert it, the machine hangs indefinatly as soon as the light on the drive lights up . I've read /var/log/messages ,and nothing is said about loading any drivers for USB storage devices . I'm stumpped ! (which doesnt take much) Please help . Thanks !
