I found that one of my cassandra nodes died recently (machine hangs).

If you "scrub" this SSTable (either with the online or offline version of "scrub") it will remove the corrupt data and re-write the rest of the SSTable which isn't corrupt into a new SSTable. That is probably safer for your data than deleting the entire set of data on this replica. When that's done, restart the repair.
