I tried activated the option to partition a disk, instead all my drive data disappeared in a few seconds
diskutil partitionDisk command does exactly what you described happening.  Partitions a disk, removing all volumes.  All volumes on the disk you ran the command on are destroyed.  So you partitioned disk4 and renamed it newdisk using GPT HFS+.  I'm not sure where you got the command information from but the command you entered did exactly what it was supposed to do.  I would recommend looking into data recovery services if you need anything that was on that drive.
