Data Recovery Services

I need to recover some files from a SCSI drive that failed over a decade ago.?? Are there data recovery services that can determine if the files on the drive can be recovered or can actually do such a recovery??? Now that I think about it, I recently also had a fairly new Western Digital drive suddenly no longer be seen by any Windows PC and I really need many of the files on it.?? Can anybody here tell me if drive manufacturers offer recovery services? I ask this since I saw a post somewhere that Seagate offers some sort of file recovery via cloud storage. As you can tell, I am by no means super-knowledgeable about modern systems since I am from the WANG 2200 MVP, WANG PC, and WANG Basic 2C era, and still have a few pieces of WANG hardware collecting dust. I apologize if I am posting this to a group where it is inappropriate. Thank You, John
