What did chkdsk do?

Hi folks,

I ran Defraggler a few times on my NTFS drive in Windows XP to defragment and move all files to the start of the HD. I wanted to make another partition and install Windows 7. It's a nice program by the way!

I noticed Defraggler listed some bad sectors, so I ran chkdsk (XP) including the scan and attempt to repair bad sectors. After a few hours it reported 0KB in bad sectors. When I came back to defrag again, I see the bad sectors are still marked and the purple MFT marker stretched from 2 blocks to like 50 blocks (and is now in a bad position near the end of the drive...).

I don't know much about harddrives (yet), but please give me some explanation or link me if you can help me understand what is going on here. :mellow:

Thanks

where do you read that there are bad sectors. normally (or better said: as standard) the purple sectors are reserved for the so called mft: there are information stored where you're files are and how they are called and so on.
