Check Disk and backups

Thread needs solution

Slightly hypothetical but anyway :)
If you make a backup of your C drive, and then run check disc and it found/fixed a bad sector/s etc, what happens if you restore the image made BEFORE check disc was run.

Is the info containing the bad sectors, held within the OS etc, meaning that info is "lost" when the backup is restored, or is it "stored" more as a firmware thing within the HDD

In other words would you have to run check disk again or not.

I think you want to fix the "bad" sectors before you run the backup--the data from those sectors is unreliable. If they haven't been marked as Bad, then ATI is going to include them in the backup. When it writes the data to a disk during a resotre, the data might not be correct even though ATI is copying exactly what it read when the backup was created.

Hi Scott,
Fortunately I've never had check disk report anything amiss... as I say it was a hypothetical question really.
If sector "xyz" was bad for example, that sector location must be stored somewhere so the HDD doesn't use it.
What I was trying to find out is whether it is stored within Windows... in which case a restored backup would be "unaware" of it, or is it stored within the HDD somewhere so it's always known.
Thanks

AFAIK, TI does not restore to the original locations anyway.
That said, I think the bad sectors are known to the HDD. Think about portable drives; every PC they get plugged into would have to know where the bad sectors are.
