I am using a Knoppix boot CD to boot a linux system which is attached to an external USB 2.0 harddisk. When I try to mount the external USB harddisk using
mount -t vfat /dev/sda5 mysda5 -o rw
The system prompts me that "wrong fs type, bad option, bad superblock on /dev/sda5". Moreover, when I try to mount the external USB harddisk using
mount -t auto /dev/sda5 mysda5 -o rw
The external USB harddisk seems to mount correctly. However, when I try to copy files into that external drive. The system prompts something like that "cannot create regular file : '/mnt/mysda5/index.htm' : read only file system".
I don't know whether it's the problem with the mount command or it's the problem due to the use of the Knoppix boot CD (the Knoppix boot CD is not writable). Moreover, I want to know that what file system I should use in the "-t" option of the mount command. Does anyone has some ideas of how to tackle this problem. Thanks for any suggestion.
