Thanks Mike!

I was able to mount one of the SATA drive (which is
part of the gmirror drive), and copy some data files
to another IDE drive (bootable). But I can not copy
some data files, there was error being printed out
that says sth. like "...UNRECOVERABLE....",

Hopefully, the data files I was able to copy is

The gmirror drive consists of two SATA drives. That I
usally boot from this gmirror drive. Do you know if I
can restore/rebuild the complete gmirror drive? If
Yes, can you please point to me some instructions?
That can save me lots of time/trouble to
reinstall/reconfigure the whole system
