If the drive is dead, as in, it has a hardware defect that keeps the computer from reading the data, you’re out of luck. For a lot of money, someone can take out the disk platter in a clean room, and read it with another read head.
If only the partitions, partition table or file system are corrupt, you can dd it to a different drive and either re-write the metadata if you know what it was or use software to recognize the start- and endpoints of the file types that are stored on it and recreate them with free tools. But you’ll lose all file names and the folder structure.
