What am I missing? CHKDSK /R adding zeros

Hello everyone.

Reading from http://support.microsoft.com/kb/314835/en-us

"When CHKDSK finds an unreadable sector, NTFS adds the cluster that contains that sector to its list of bad clusters. If the bad cluster is in use, CHKDSK allocates a new cluster to do the job of the bad cluster. If you are using a fault-tolerant disk, NTFS recovers the bad cluster's data and writes the data to the newly allocated cluster. Otherwise, the new cluster is filled with a pattern of 0xFF bytes."

I had a file that had a bad cluster and I understand it is corrupted and am not trying to get it back or anything like that.

My question is, when I open the file in a hex editor, the bytes in the new cluster consist of 00 and not the FF I had expected after reading the Microsoft support page?

Thanks.

  1. The sector may be marked as bad in the MFT, not necessarily the file itself since the sector is bad and can't be written to.
