I have a freebsd system.
In my computer /dev/sda10 is a freebsd slice.
I use mount -t ufs /dev/sda10 /tmp
It fail.
mount: wrong fs type, bad option, bad superblock on /dev/sda10,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
How can i mount it?
