I don't see anything particular that "pops out" - but I'm no file system hacker. This is the output of: dumpfs /dev/rsd0a immediately after doing: newfs -b 8192 -f 1024 /dev/rsd0a [The time stamp is wrong because the machine's internal clock is confused, but I just a minute ago did this...] Recall - it's inode #7680 that's causing my problems... Let me know if there's anything I can do... - Dave Rivers - p.s.
