: and 34.

If the data from 23 to 34 is not catalog'd, then it is
actually not good data. You may be able to recover files
from it, but not conventionally, so therefore it must
have had other data on it before what is catalog'd now.
A disk utility may be able to recover some of that data,
but would it be worthwhile in the long run???
