FreeBSD crashed

[gahn]

Hello all:

My FreeBSD crashed. It boots fine but can't mount root directory. Here is the message:

/////////////////////////////////////////////////////////////
...
....
Trying to mount root from ufs:/dev/ad0s2a

Manual root filesystem specification:
     <fstype>:<device> Mount <device> using filesystem <fstype>
                                     eg. ufs:da0s1a
     ?                          List valid disk boot devices
     <empty line>         Abort manual input

mountroot>

///////////////////////////////////////////////////////////////          


Could any gurus here help me out this? I just want to save the files in the home directory so that I can rebuild the system.

Regards

Dave
