Data Recovery and HDD repair sometimes have the same purpose, for example, when HDD repair is performed to do data recovery, some drives are not detected due to firmware failure, head damage, PCB burnt, motor stuck, platter scratches, etc, you need to repair first and recover the data. But when you are going to use data recovery or hdd repair tools, you must understand which functions are safe to use especially when you need data. Sometimes data recovery and hdd repair go the opposite way: when you perform hdd repair, you destroy the data but you get the drive working again. LIke you do some selfscan, you clear P-list, you write some modules which are not donors, you modify some modules, etc.
Another difference we may notice is that the hardware cost for data recovery is higher than that of hdd repair.
