I have searched and searched for an answer to this but cant find one! Can anyone help? I have several hard drives taken from windows 10 and windows 8 laptops that need the data recovering from them. I am running a windows 7 ultimate desktop. I have attempted to put the windows 10/8 hard drives in a dock and power them up. Windows 7 doesn't seem to recognize them, disk management shows them as not initialized. Obviously initializing them will reformat the partition so I can't do that. The only way I have been able to recover anything is with separate recovery software which detects the drives as "lost partition" This then takes 3-4 hours or recovery just to get the files back organised by type rather than by file structure, making it nearly impossible for me to recover any structure with the files. Does anyone have any idea whats going on here and why I cant just fire the drives up and see the structure as I would any other external drive. All the drives are physically sound by the way the issue with the laptops being failed motherboards rather than drive failure.
