How about downloading FreeSBIE on another computer, burning it to an ISO and
using that? I've never used the fixit CD but FreeSBIE is based on 5.2.1 and
may have better luck. maybe.

On the same vain you could try knoppix, though I'm not sure that the Linux
kernel is compiled with support for UFS. A completely different code base
may have some luck disentangling your dying drive.
