DiskWarrior failed to fix a B-tree error. Any hope left?


my recent (2012) macbook pro failed , catastrophically last week "invalid b-tree node size error" (a solid freeze , forced restart seems have done it).

after forum perusing, purchased , ran diskwarrior on drive minimal success. able create new index allowed me save few of files had not been backed up. of user directory contents not restored diskwarrior-created index, didn't save changes diskwarrior had made.

non-backed-up files aren't worth paying full data recovery service, if there's still hope restore them software, willing pay $150 apple asking return drive me after full applecare replacement.

so, that's question. b-tree error, there still hope if diskwarrior has failed?
