In the case of physical failure ( defective sectors , slowness and out of order areas), if the disk is still usable by the user, a clone must be created. This clone will avoid all Data Recovery physical problems of the source disk. With luck, this disk could boot the host machine. 

But, if the clone contains misplaced read errors, it may not work. In this case, the desired Data Recovery must be extracted from it in order to integrate them into a new disk containing a new installation. Previously installed software and drivers, even retrieved, are absolutely useless.

The logical failure concerns the file system or the OS. That is, the disc cannot start the host PC. Therefore, no need to make a clone of it (except for security reasons). Because cloning will reproduce exactly the same errors and defects of the original disc. 

In this case, only the personal data is recoverable. Installed software, its Twitter data, drivers, etc., are absolutely useless. If this disk was running a production machine, you will have to perform a new installation to run this machine.

HS PC data recovery can make sense if the personal data is important. Otherwise, it would be better to carry out a new installation in order to restart the PC, in particular if the problem came from a hard disk in logical failure. Very often, the OS, drivers and software are only of interest for production machines.
