Well, when you format the disc the sectors are listed in the MFT (missing 
out any parts of the disc that the HDD firmware has flagged as "bad") so, 
until you actually write data to the disc, chkdsk has no data to check and 
all the sectors are "good". If there are any parts of the disc surface with 
physical defects (as opposed to just corrupted data) the HDD firmware's 
error correction is supposed to prevent the OS from using that portion of 
the disc in any case. When the HDD is on the way out, the error correction 
can no longer cope - and so, the disc becomes un-usable.

So, if you are getting bad sector errors as soon as you add data to the 
disc, I would suspect the HDD of having problems.
