Title: Bad sectors or maybe not?
Post by: jferraro on May 21, 2009, 01:23:45 PM

I have a hard drive which was giving me problems so I ran a chkdsk and it reported 40KB in bad sectors. I then formatted the drive. Now when I run a chkdsk, it reports no bad sectors.

What happened to the bad sectors??

It will normally segment them so they cannot be written to anymore...therefore they no longer show up.
They are not fixed...just blocked .

Will the hard drive now report a different size, or is that a matter of the number of sectors which have become blocked?

The following topic makes it seem like if the formatting encountered no errors, that it means the drive has no bad sectors:

So, now I am confused. How do I tell if hard drive now has no bad sectors or if it now has bad sectors being blocked so that chkdsk reports no bad sectors??
