Hard drive data recovery: A complicated process

Hard drive data recovery is an extremely complicated process that has become quite trivialized in the past several years.  It seems like just about every local town computer service center advertises having some form of data recovery.  It's important to consider what is required for a normal data recovery Project.  Whoever is repairing the hard drive must have good knowledge of various hard drive technologies, both mechanical and electrical, and obviously be capable of actually repairing the hard drive.  There must also be access to a clean, sterile, facility in which the examination and repair of a damaged hard drive can take place using hard drive data recovery .  Whoever is performing the hard drive data recovery must be able to locate and repair critical system components like a boot sectors/blocks, partition tables, file allocation tables, masterfile tables, superblocks, etc.  They must always work from a clone drive and never the original drive.
