I'm trying not to equate lack of response to lack of chance of  
receovery! However...

After 4 days dd eventually successfully created a 1.5TB image file of  
the trashed partition, so i can work on it without causing further  
damage. I successfully attached it with mdconfig. Running fsck_ufs on  
the resultant /dev/md0 causes fsck_ufs to eventually crash out with:

UNKNOWN FILE TYPE I=42151497
UNEXPECTED SOFT UPDATE INCONSISTENCY

CLEAR? yes

fsck_ufs: bad inode number 42158080 to nextinode

during Phase 1. Is there anyway to get around this so fsck can continue?

Thanks in advance.

Greg.
