as u can tell from the pic
the problem is the b-tree catalog "keys out of order"
if u google b-tree catalog keys out of order u get alot of other people with the same problem
diehard has encountered this problem many times and says the only way to avoid it is to not have any verison of X on any partition on the G4....
the other posts all say i need to reformat and reinstall and that this problem cant be fixed..
i dont understand how its such an extreme problem that 'cant be fixed by disk first aid'
even disk warrior 2.1 says "the disk is too damaged"
