Hello, I am using mhdd to test and repair my hard drives, but, I was thinking...maybe I can use some better program to do that kind of things??

I use it to erase delays, repair bad sectors...and not much more.

Any recomendations??

Thanks a lot.

that is the best one i think that around.

not sure if a hard drive can repair bad sectors at all
its more likely just cliping it so it does not put any data on there

Need hw/sw tools and work with err list or start internal selfscan and fix it completely. But it will cost you thousand $...

Using MHDD I have the sense of that it pass by each sector but don't clip it, becouse I see always almost the same sectors in every lap, usind loop test and erase time delays...

Im doing something wrong??

No, simply your problem is beyond the possibilities of a free software. That's all.
