CheckIndex is not able to recover from this corruption (missing segments_N file); this would be a nice addition...
But it sounds like you've worked out a way to write your own segmetns_N? Use oal.store.ChecksumIndexOutput (wraps any other IndexOutput) to properly write the checksum. BTW how did you lose your segments_N file...?
