Still running a long time. There is something wrong with unallocated clusters : When starting the following loop in destroy_record : for (j = rl[i].lcn; (j < rl[i].lcn + rl[i].length) && (ret_wfs == 0); j++) I get j -1 lcn 0xffffffffffffffff length 1953125000000 This is bound to take a long time, and lcn == -1 means unallocated. > About the second problem: apply the attached patch over the previous > one and check if the internal errors have the "Extents:" comment in > front.
