Says No bad sectors but defrag shows it

I got a new Hard drive a cople weeks a go. I ran scan disc and it said I have 0 bad sectors. When I ran defrag and "viewed" it defraging I saw the red ones that repersent bad sectors. Why does it say I have 0 (zero) bad sectors but show in Defrag? Chris.

 

IF you run Defrag and it also completes with no problems those little boxes with the X are files that Windows does move. If you see a whole lot in a goup ( several line worth ) that will be the swap file.

Scandisk reports bad sectors on the first pass in which they are found. It then marks them as bad and they are removed from the FAT's list of usable sectors. After that first pass, they are then treated as though they don't exist. That is why, on subsequent scans, no bad sectors are reported.

 

I believe scandisk only does this when run as scandisk /surface and then they are marked and show with a B in the box.

But either way they do not show up in Defrag.

That is correct, BillyBob.

 

edit/correction to my first reply

X are files that Windows does move

That should read that Defrag does NOT move.

Staples has a 14 day in store return policy wich ends tomorrow (thursday, 2nd). How do I find out if I should take it back? Scan disc never came up with bad sectors since I got it.

 

Well, according to what you've written, you haven't mentioned anything that indicates bad sectors. Why do you think you need to return it?

 

OK, I finally got it. I checked "Legin" and it said there is two types of red. My red was unmovieable and not the bad sectors red. Thank you for replying. The good old (New) Maxtor Drive is in great shape.

 

Gee !! Did I not see that mentioned somewhere before ?

If they were actually bad sectors scandisk or defrag would not have completed.

As I mentioned before bad sectors do not show anywhere other than Scandisk /surface.

Or Norton Disk Doctor with surface check.

If this has changed will someone please let me know.

"If they were actually bad sectors scandisk or defrag would not have completed "
On my old HD I had many bad sectors and defrag worked fine.

 

Then either your machine is quite different than mine or else Scandisk /surface or Norton DiskDoctor had been run to mark them bad so that they did not get used.

I have never had defrag complete on a disk with unmarked bad sectors.

I do have one HD on one machine right now that has something like 60-70 bad sectors. but they are marked as bad and defrag does complete. But it would not before.

Last time I looked was about a week ago and unless it changed since then, it is still the same.
