Hello, scaning with mhdd I found one sector (26775240) that mhdd says this.

What's the meaning of that? Can I fix that sector?

Thanks!

NO. You can only remap it to make it hidden. Of course if there is data on it, the pertinent file will be corrupted.

What about sectors that come up UNC because of incorrect ECC data? Rewriting them (ie with MHDD erase) will restore them to being usable. Of course if it was caused by a physical fault in the first place they will probably just come back...

He said "fix" most probably meaning get correct data. With no tool you can't say if it is UNC caused by ECC or physical problem, so the 1st thing that comes to mind is the answer (NO) and the solution (REMAP) this is 100% correct.
