In elastic search if a node crashes then data can be recovered from it
replicas.
But what happens if a single node's hard disk crashes and data is
lost.
Is there any mechanism to recover data then ?
Thanks in advance for any help

You mean you run a single node cluster, and the data is lost? No, in this
case, there is no way to recover the data.

Except with a gateway writing to another server.
How about if there is data file corruption in a cluster with
replicated nodes, will the error be replicated to other healthy node?
Thanks a lot.

Because elasticsearch does push replication, other shards index the data as
well, so a corruption will not propagate to other nodes.
