Hi,

I encountered bad sector on my disk during dump:

wd0g: error reading fsbn 237235392 of 237235392-237235455 (wd0 bn 268435455; cn 266305 tn 0 sn 15)
wd0: (id not found)

First question: what kind of error is this (id not found)?

Second question: how can I determine the file occupying that sector?
I know of a method using bad144 and badsector.  Is there a more
straightforward method?
