Yes, it is safe for healthy drives. It performs a non-destructive read-write test. However, running an "Aging Test" or "Bad Block Scan" on a drive that is already physically failing could accelerate its final failure. This is true for any testing tool. It's best to use it on a drive you are suspicious of and have no critical data on.
