Hi reno
I dont know if I understand correctly but "harddrive protection" & "a repairer for hard drive errors" are not something we can help with.
None of our software will protect your PC from irregular shutdown or hard drive errors in any way.
If you need some kind of 'Os' or 'hard drive' protection I recommend you should look at an 'embedded' operating system like windows XP or 7 'embedded'.
