I have a 500GB hard drive that failed. I have tried other software to very limited success. I just found Disk Drill and thought it might help. I began by trying to make a backup image for safe keeping. After about 28 hours, it completed about 1.61%. It this time typical? Is it most likely a hardware issue with the drive? Would I be best served finding a recovery company that would remove the platters or something like that, to bypass the hardware issue? Any good advise would be helpful.
