Its low level task, repairing seq files with header missing is not so
easy. But till date we were able to repair pretty much everything people
needed including corrupted hbase metadata. But its few days of work,
which is far beyond you can get for free in community mailing list.

no, it does more harm then good. Best advice is never try to do any data
recovery yourself and seek an expert.
But if cost of expert work is more then cost of data, then yes why not
to try it? I never used that myself, but you probably do not have much
