How to mount a slice that is flaged unmountable?

909400Jan 6 2012 — edited Jan 8 2012

Solaris 11 experts,

I just got an external HDD that cannot be mounted correctly. I'm using Solaris 11 x86 64bit. The external HDD was formatted using a SUN Netra 440 running Solaris 10.

First, the fs_type seems to be wrong. I have checked the MBR in a hex editor and it says 0xBF which is a new Solaris x86 partition (UFS). Don't know why Solaris 11 thinks it is incorrect... Secondly, the slices seem to be marked as unmountable (flag = 01)...

Beneath I submit some output from different tools.

Can anybody see what should be done to be able to mount it?

(I have also tried to use UFSExplorer on Windows 7, but with no success...)
