i have two thumb drives. i one thumb drive i can mount with the following command
mount -t vfat /dev/sda1 /mnt/usb
that command works fine, but when i plug in my other thumb drive (after i umount it)
i typed in that same command above and it fails by saying
mount: /dev/sda1 is not a valid block device
I don't understand why this is happening...is it because the thumb drive is bad, if so is there a way i can retreive the data from it, or i'm i screwed?
