Bad Sector not recovered

[etness]

Hi,

I have a HDD Maxtor DiamondMax 10 family (SATA/300) 6V160E0, my hard disk has one bad sector. I would like mark this sector as bad so my OS don't try to access it.
I tried many software for example HDD Regeneration and SpinRite but these softwares when analize the bad sector stay many minutes also one hour without resolve the problem and without tell me I can't resolve the problem. So I tried MHDD also this software tell me there is a problem on the bad sector, but when I mark it as bad with makebad, the OS continue to access it and slow down the access to HDD. With command makebad I set the same start and end sector with my bad sector is it correct?
Is it possibile mark the bad sector with SMART? Is there another software for mark the sector as bad? Why the makebad not work for me?

Thanks for help

The drive is dying. Consider this as your early warning. I am going to guess you have no backups as well. Replace it.

The cause of bad sector is brutal power off while OS write on it.
Why mhdd 4.6 not mark the sector as bad when I tell with makebad?

That is an academic question. Do you have a backup of this drive?

Please back it up and replace it.

Academic questions can be fun to answer, but first you need to ensure that you get the data off that drive immediately. Believe me, when it finally dies, it will be extremely expensive to get it back.

Why do you want MHDD to mark sector as bad when it is already bad? This makes no sense. Use scan then remap then erase waits. It sounds its not a logical bad sector so this may not work. back up before you do anything.

With MHDD I used scan and erase of sector the problem is resolved I lost 512 byte but it's not a big problem. The check with write test of all HD report status good.
Now after this experience I have some doubts, a bad sector is different from a sector UNC? When there is a fisical damage on hard disk the controller mark it as bad automatically?

Thank you very much to all for the help and the advice "backup your data".

Which is the operation of command makebad in MHDD?

Hdds automatically isolate and relocate errors during lifetime, on a certain extent. User can control it, but only to a defined point. Beyond, only specialized systems can work (i.e. Access/modify Error Lists)
