Isolating Bad sectors on system disk after recovering them with HDDreg

pGr · 17 Feb 2014

Hello Windows 7 expertises,

how can I isolate semi-damaged sectors on the windows system disk ?

computer start freezing for some actions (like reading the fonts) and I thoght about hd problems, I runned a HDDreg that I have in a bootable USB and discovered that 8 sectors (from 704920 to 704927, around 450 Mb) where Bad, I recover with HDDreg and working again.

The thing, I am on the go and I do not have time to change hard disk and install all from fresh, so I would like to prevent it from failing. So I would like to isolate or mark those sectors (and few near) to not be used by the system

Is that possible?
How should I do it ?

I presume that using chkdsk is of not so much use, as hddreg "recover" this sectors.

I just run CrystalDiskInfo to tell me what I know: CAUTION !!
with Reallocated Sectors Count as Current:100 Worst:100 Threshold:50 RAW:00000008
Disk is a TOSHIBA MK5075GSX Disk Size : 500.1 GB (8.4/137.4/500.1)
With Power On Hours : 10817 hours and Power On Count : 242 count

(I notice now I have post it in the wrong category, please move to the right one if you need, sorry)

Chkdsk, will move bad sectors so they are not used. It will take this action a limited number of times. After too many sectors have to be moved, it might be best to invest in a new HD.
You must check both the first and second box when asked what action you want. It will take at least an hour to complete the test

As I said before, I used HDDregenerator to regenerate the bad sectors, so right now, they are working properly, but I assume that that they could fail easily

that way I want to tell the system, not to use this sectors.
For the moment, only seven consecutive sectors are found

I made it from cmd as chkdsk /x /b c:, and the result say there are not bad sectors :
