Well, with some experimentation and a map of where my directories
are on the disk (thanx, Grant), I'm going to attempt to put some
of my subdirectories back together again.
 
Can someone point out what the 1st directory entry looks like?
I know this is Beneath Apple ProDOS stuff, but I'm at school
and I don't want to buy another copy...
 
Thus far, I've figured out...
 
 x0 x1 y0 y1 z0 n0 n1 n2 n3 n4 n5 n6 n7 n8 n9 na nb nc nd ne $76
 00 00 00 00 00 00 00 etc...
 
 where x0 and x1 are the low and high block bytes of the previous dir.
 where y0 and y1 are the low and high block bytes of the next     dir.
 where n0 through ne are the 15 chars of the ProDOS name followed by
   Hex $76 and 7 bytes of 00.
 
 Next comes some other data which I assume points to the block
 where the data is.  Then, the second entry.
 
 But, what is n0, the 5th ProDOS byte?  And, is the second entry
 like the first (after the 5th byte)?  If not, how does it differ?
 
As to my hard drive, it appears as if the directory was zero'ed in
part.  Once I get it back to normal, I'll back it all up and
reformat the whole thing.
